Any catalyst should be efficient and stable to be implemented in practice. This requirement is particularly valid for manganese hydrogenation catalysts. While representing a more sustainable alternative to conventional noble metal-based systems, manganese hydrogenation catalysts are prone to degrade under catalytic conditions once operation temperatures are high. Herein, we report a highly efficient Mn(I)-CNP pre-catalyst which gives rise to the excellent productivity (TOF degrees up to 41 000h(-1)) and stability (TON up to 200 000) in hydrogenation catalysis. This system enables near-quantitative hydrogenation of ketones, imines, aldehydes and formate esters at the catalyst loadings as low as 5-200 p.p.m. Our analysis points to the crucial role of the catalyst activation step for the catalytic performance and stability of the system. While conventional activation employing alkoxide bases can ultimately provide catalytically competent species under hydrogen atmosphere, activation of Mn(I) pre-catalyst with hydride donor promoters, e.g. KHBEt3, dramatically improves catalytic performance of the system and eliminates induction times associated with slow catalyst activation. Manganese-based hydrogenation catalysts are sensitive to high temperatures and may degrade under industrially relevant conditions. Here, the authors report a highly efficient manganese pincer pre-catalyst displaying high TOF values (up to 41 000 h(-1)) and stability (TON up to 200 000) at loadings as low as 5-200 ppm.

Although synthetic antioxidants (AOs) and photoinitiators (PIs) are known to be used in printing inks, there are little data on residual concentrations in printing paper products. In the present study, twenty-five PIs, ten AOs, and six transformation products were analyzed in two types of printing paper products, magazines and paperboard food packaging materials, both of which are unavoidable everyday products in our life. Nine AOs and six transformation products can be detected in food packaging materials with total concentrations (geometric mean, GM) of 1.16 x 10(4) ng/dm2. Twenty-two PIs were detected in food packaging materials with total concentrations (GM) of 1.76 x 10(4) ng/dm2. These chemicals were also detected in magazines, albeit at low concentrations (GM of AOs: 466 ng/dm(2), GM of PIs: 1.17 x 10(3) ng/dm(2)). Magazine front covers were found to have much higher concentrations of the target compounds than magazine inside pages. Tris(2,4-di-tert-butylphenyl) phosphate (AO168O), 2,6-di-tert-butyl-4-methylphenol (BHT), bisphenol A (BPA), and benzophenone (BP) were among the predominant chemicals in those printing paper products. Preliminary calculations suggest that dermal exposure to AOs (GM: 6.25 ng/day) and PIs (GM: 17.0 ng/day) via contact with printing paper products is a minor exposure pathway compared to food intake/dust ingestion and is exceedingly unlikely to cause adverse health effects.

Sample introduction method was studied to reduce the extra-column effect in reversed-phase HPLC. Slow transport of a sample band (SToSB) in the pre-column space followed by the introduction of the band into the column at a near-optimum flow rate resulted in larger plate counts for a 1.0 mmID, 5 cm long column as much as 1.4-1.6 times for solutes with a retention factor (k) of 0.5-1.8 compared to a conventional elution method. Further reduction of the extra-column effect was possible by orthogonally splitting the sample band (SplSB) by flow switching during its slow transport followed by the introduction of the leading part of the band into the column. In this case, increased plate counts of up to 2-3 times for solutes with k of 0.5-1.8 were observed for a 1.0 mmID, 5 cm column. The sample introduction method, SToSB in the injector and the pre-column tube of a few mu L, was found to reduce the extra-column band variance by 0.4-0.5 mu L-2 for an UHPLC system with the extra-column volume (V-extra) of ca. 4.6 mu L and the system variance (sigma(2)(extra)) of 1.1 mu L-2 at flow rate of 100 mu L/min, while SToSB and subsequent SplSB were found to be more effective, reducing sigma(2)(extra) by about 0.8 mu L-2. With an UHPLC instrument with V(extra )of about 10 mu L and sigma(2)(extra) of ca. 3.6 mu L-2 at flow rate of 300 mu L/min, 1.4-2.1 times as many plate counts were observed with SToSB and SplSB compared to the normal elution method for early-eluting solutes with k=0.25-1.7 for a column, 2.1 mmID, 5 cm long. With this UHPLC instrument, SToSB and/or SplSB resulted in the reduction of sigma(2)(extra) by 1.2-2.2 mu L-2. (C) 2021 Elsevier B.V. All rights reserved.

In this paper, several Mn(I) complexes were applied as catalysts for the homogeneous hydrogenation of ketones. The most active precatalyst is the bench-stable alkyl bisphosphine Mn(I) complexfac-[Mn(dippe) (CO)(3)(CH2CH2CH3)]. The reaction proceeds at room temperature under base-free conditions with a catalyst loading of 3 mol % and a hydrogen pressure of 10 bar. A temperature-dependent selectivity for the reduction of alpha,beta-unsaturated carbonyls was observed. At room temperature, the carbonyl group was selectively hydrogenated, while the C=C bond stayed intact. At 60 degrees C, fully saturated systems were obtained. A plausible mechanism based on DFT calculations which involves an inner-sphere hydride transfer is proposed.

The oxidation of hydrocarbons to produce high value-added compounds (ketones or alcohols) using oxygen in air as the only oxidant is an efficient synthetic strategy from both environmental and economic views. Herein, we successfully synthesized cobalt single atom site catalysts (Co SACs) with high metal loading of 23.58 wt.% supported on carbon nitride (CN), which showed excellent catalytic properties for oxidation of ethylbenzene in air. Moreover, Co SACs show a much higher turn-over frequency (19.6 h(-1)) than other reported non-noble catalysts under the same condition. Comparatively, the as-obtained nanosized or homogenous Co catalysts are inert to this reaction. Co SACs also exhibit high selectivity (97%) and stability (unchanged after five runs) in this reaction. DFT calculations reveal that Co SACs show a low energy barrier in the first elementary step and a high resistance to water, which result in the robust catalytic performance for this reaction.

Wildfires have become more common and intense in the western US over recent decades due to a combination of historical land management practices and warming climate. Emissions from large-scale fires now frequently affect populated regions such as the San Francisco Bay Area during the fall wildfire season, with documented impacts of the resulting particulate matter on human health. Health impacts of exposure to wildfire emissions depend on the chemical composition of particulate matter, but the molecular composition of the real biomass burning organic aerosol (BBOA) that reaches large population centers remains insufficiently characterized. We took PM2.5 (particles having aerodynamic diameters less than or equal to 2.5 mu m) samples at the University of California, Berkeley campus (similar to 60 km downwind of the fires) during the October 2017 Northern California wildfires period and analyzed molecular composition of OA using a two-dimensional gas chromatography coupled with high-resolution time-of-flight mass spectrometry (GCxGC HR-ToF-MS). Sugar-like compounds were the most abundant component of BBOA, followed by mono-carboxylic acids, aromatic compounds, other oxygenated compounds, and terpenoids. The vast majority of compounds detected in smoke have unknown health impacts. Regression models were trained to predict the saturation vapor pressure and averaged carbon oxidation state ((OSc) over bar) of detected compounds. The compounds speciated have a wide volatility distribution and most of them are highly oxygenated. In addition, time series of primary BBOA tracers observed in Berkeley were found to be indicative of the types of plants in the ecosystems burned in Napa and Sonoma, and could be used to differentiate the regions from which the smoke must have originated. Commonly used secondary BBOA markers like 4-nitrocatechol were enhanced when plumes aged, but their very fast formation caused them to have similar temporal variation as primary BBOA tracers. Using hierarchical clustering analysis, we classified compounds into seven factors indicative of their sources and transformation processes, identifying a unique daytime secondary BBOA factor. Chemicals associated with this factor include multifunctional acids and oxygenated aromatic compounds. These compounds have high (OSc) over bar, and they are also semi-volatile. We observed no net particle-phase organic carbon formation, which indicates an approximate balance between the mass of evaporated organic carbonaceous compounds and the addition of secondary organic carbonaceous compounds.

The volatile compounds of Jiaozi-steamed breads (JSBs) fermented by Jiaozi starters from eight regions in China were extracted using simultaneous distillation and extraction (SDE) and headspace solid-phase microextraction and determined using gas chromatography-mass spectrometry (GC-MS). 1-Hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid were the main volatiles of JSBs. Principal component analysis exhibited that the volatiles of JSBs from Nanyang City, Xi’an City, and Zhumadian City was negatively correlated to that of other five JSB samples. Cluster analysis demonstrated that the volatile characteristics of JSBs from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City belonged to a category, and the JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. It demonstrated that the volatile components of steamed breads in North China and South China were different. Practical applications From this study, it can be seen that simultaneous distillation and extraction (SDE) can completely extract volatile compositions of steamed breads fermented by Chinese traditional starter Jiaozi. SDE/GC-MS was suitable for the analysis of JSBs volatile composition. The relative contents of 1-hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid in JSBs were at high level, and their contents could be used as a marker to identify JSBs. The volatile compositions of JSBs made of Jiaozi starters from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City were similar. However, JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. The volatile components of steamed breads in North China and South China were different, which reflected the difference in dietary habit in the southern and northern areas of China.

Fluorescent materials with a large enough Stokes shift (>100 nm) have widely prospect in light conversion agricultural film, cell-imaging, chemosensory and so on. However, most of traditional fluorescent dyes displayed small Stokes shifts which severely limited their application. In this paper, a side-chain alternative copolymer named P(DMPNI-alt-TPE) was developed, in which the two fluorophores were next to each other: the AIE-active tetraphenylethene (TPE) acted as energy donor, while naphthalimide derivative (DMPNI) with intramolecular charge transfer (ICT) character as energy acceptor. Attributed to this unique structure, the copolymer combined efficient dark/fluorescence resonance energy transfer (DRET/FRET) and polarity-sensitivity. And therefore it showed impressive large pseudo-Stokes Shift up to 304 nm and 302 nm in solution and aggregative state respectively. Interestingly, this copolymer exhibited a V-shaped fluorescence variation curve in a series of THF solutions with increasing fraction of water. Moreover, P(DMPNI-alt-TPE) emitted different color fluorescence in various solvents upon UV light, so that its pseudo-Stokes shift was not only large but also tunable, and the changing range was from 262 to 304 nm. Lastly, the potential possibility of P(DMPNI-alt-TPE) as light conversion agricultural film was investigated. This research provided a new approach for the development of fluorescence materials with large and tunable Stokes shift.

The impact of volatile organic compounds (VOCs) and odor on indoor environment and people has attracted much attention. To reduce this problem of odorous compounds contained in wood panel, this study focused on identifying odorant compounds and exploring the influence of moisture content factors on VOCs and odor emissions. Paper mulberry (Broussonetia papyrifera (L.)Vent.) was investigated using the technology of gas chromatography-mass spectrometry/olfactory (GC-MS/O). Total volatile organic compounds (TVOC) and characteristic odor-active compounds were studied, and the emission of heartwood and sapwood of paper mulberry was compared at the same time. It was found that the main components from heartwood and sapwood were aromatics, alkanes, alkenes, aldehydes ketones, alcohols and esters. Totally, 23 kinds of odor-active compounds were identified from heartwood and sapwood of paper mulberry, among which, aromatics and aldehydes ketones were the main odorant compounds. Seven kinds of key odorant compounds were identified in this process. With the decrease in moisture content, the TVOC and total odor intensity of heartwood and sapwood generally decreased. The moisture content had a great effect on VOC release when the moisture content decreased from 70 to 50% and reduced from fiber saturation point (30%) to air saturation point (10%). The main odor impressions of paper mulberry were aromatic, fresh fruit fragrance, sweet scent and special pungent. In the whole process of moisture content decrease, the TVOC, concentration of odorant and odor intensity of sapwood were higher than that of heartwood.

Herein, we report the development of a tailor-made fluoride-based heterogeneous catalyst, POLITAG-F, for the waste-minimized continuous production of cyanohydrin silyl ethers. The careful designing of the polymeric support and the choice of fluoride ion as the anionic species resulted in the improvement of catalytic efficiency and allowed the effective conversion of different carbonyls (aldehydes, ketones, and unsaturated ketones). The POLITAG-F catalyst, employed under flow conditions, led to the conversion of large amounts (over 100 mmol) of the substrate with a productivity of 0.1 mmol min(-1). In addition, flow conditions allowed to minimize the waste production reaching an associated E-factor value of 0.04. An exhaustive evaluation of the environmental impact of our protocol has been reported by considering several green metrics (process mass intensity, atom economy, and reaction mass efficiency) and also the benign index and the safety hazard index of the process.
