Atmospheric fine particle (PM2.5) samples were collected over a whole year (April 2016 – March 2017) across five sampling locations in the Beijing-Tianjin-Hebei (BTH) region, to investigate the occurrence of novel brominated flame retardants (NBFRs) and polybrominated diphenyl ethers (PBDEs). The concentrations of Sigma(9)NBFRs were in the range of 0.63-104 pg/m(3) (15.6 +/- 16.8 pg/m(3)) in atmospheric PM2.5, while the levels of Sigma 9PBDEs (excluding BDE-209) ranged from 0.05 to 19.1 pg/m(3) (2.9 +/- 3.8 pg/m(3)) and BDE-209 concentrations ranged from 0.88 to 138 pg/m(3) (22 +/- 28 pg/m(3)). Relatively higher levels of NBFRs and PBDEs were found at urban sampling sites in Beijing City and Shijiazhuang City. Decabromodiphenylethane (DBDPE) and BDE-209 were the dominant compounds with the relative abundances of 72% in Sigma(9)NBFRs and 90% in Sigma 10PBDEs, respectively. Generally, the levels of most target BFRs in summer were lower than those in other seasons. However, there were no notable seasonal differences in levels of DBDPE and BDE-209 in atmospheric PM2.5 samples across the BTH region. Significant and positive correlations were found between the concentrations of BFRs and PM2.5. Daily human exposure via inhalation revealed that children have a higher probability of suffering from the adverse effects of BFRs than that of adults. In addition, residents living near sampling locations across the BTH region may suffer high exposure risks to BDE-209 and NBFRs.

Rice husk, rich in silica and abundantly available as waste, is presently destroyed by burning, which creates environmental issues. Thus, it will be advantageous if this rice husk waste can be used for preparation of valuable products. One of the application is its use as silica source in the synthesis of zeolites like ZSM-5, which are silico-aluminates. Rice husk waste is available in wide range of particle sizes in agricultural farms. There is no study available in open literature on use of these wide particle ranges for its direct application. This paper is an attempt to use wide particle size rice husk, its effect on ZSM-5 synthesis and its physico-chemical properties. Further these prepared ZSM-5 catalyst was evaluated for benzylation of mesitylene reaction. The study found that, rice husk of 600 mu m particle size is optimum as far as ZSM-5 synthesis, its physicochemical properties and further its application in mesitylene benzylation reaction.

Studies of environmentally benign catalytic methods are of great value in modern chemical synthesis, especially the chemo-selective construction of chemical bonds under green conditions. This work elucidates such preferential synthesis of C-N bond over C-O bond via selective N-arylation of 3-aminophenols using 1,3-bis-[2-hydroxyphenyl] imidazolium chloride (IHPHCl) and copper iodide as catalyst (1 mol %) in aqueous medium. Presence of chelating group (-OH) on IHPHCl enhances N-selectivity. Overall this is a simple and green method for selective N-arylation of 3-aminophenols with good substrate scope and yields (60-88 %). GC-MS, HRMS and other spectroscopic techniques were utilised in detailing the kinetics and mechanistic aspects.

This paper describes the pyrolysis of Poplar fluff (from Populus alba) using on-line apparatus, and carbonization process at 850 degrees C using the fixed bed reactor. Characteristics of pyrolysis products were examined. Elemental and chemical analyses were shown that Poplar fluff has higher energy content characterized by increased content of fibrous structure (particularly cellulose). Independent parallel reactions model very well describes devolatilization process. It was found that increased amount of extractives can significantly affect on increased release of light gaseous products, but declining hydrocarbons, mostly the alkanes. Liquid product is mainly composed of phenolics, aldehydes, acids, esters and ketones. The carbonization process produces the great abundance of polycyclic aromatic hydrocarbons (PAH’s), where naphthalene is the most abundant. Mechanism for PAH’s formation was suggested. This study represents the first step in a much wider and more comprehensive way in thermal conversion processes of this type of fuel.

Guillermo Calleja and co-workers from @urjc describe URJC-1-MOF as a new heterogeneous recyclable catalyst for c-heteroatom coupling reactions The capacity of copper-based URJC-1-MOF as a MOF catalyst in cross-coupling reactions has been evaluated, focusing on the Chan-Lam-Evans arylation-type reactions on amines and alcohols without extra additives or ligands. The extraordinary chemical and structural stability of URJC-1-MOF and its good specific surface, make this material a promising alternative to homogeneous Cu (II) catalysts for cross-coupling reactions. URJC-1-MOF showed a remarkable catalytic activity for cross-coupling C-N and C-O reactions, higher than other heterogeneous and homogeneous copper-based catalyst, such as CuO, HKUST-1, Cu-MOF-74, Cu(OAc)(2) and CuSO4.5H(2)O. Moreover, its easy recovery by simple filtration and reusability in successive runs without any loss of activity and stability, demonstrates the potential of URJC-1-MOF as an alternative catalyst for this kind of reactions in different chemical media of industrial interest.

Phenol and its derivatives, which naturally occur in lignocellulose, can be considered as a renewable feedstock not only for aromatic, but also for alicyclic compounds, such as primary and N-substituted cyclohexylamines. So far, the latter are mostly produced from non-renewable starting materials like benzene via problematic nitration/reduction or cross-coupling routes. Herein, an efficient reductive amination of phenol with ammonia or amines is demonstrated, for the first time without the need for rare and expensive noble metals and without using any additives. Various supported Ni catalysts were screened and we elucidated the influence of the key parameters, including the acid-base properties of the supporting material. Acquired knowledge was then applied to different phenol-ammonia/amine combinations, resulting in the synthesis of various primary, secondary and tertiary cyclohexylamines in fair to very high yields.

RuFe/CeO2 catalysts were studied in the hydrodeoxygenation (HDO) of diphenyl ether (DPE). We find that the hydrogenation reactivity is favored over 2Ru/CeO2, leading to the formation of dicyclohexyl ether and cyclohexyl phenyl ether as main products. Addition of oxophilic Fe inhibits the hydrogenation of aromatic rings but enhances the hydrogenolysis of C-O bonds to produce benzene and phenol as well as cyclohexane and cyclohexanol formed from subsequent hydrogenation of phenol. similar to 92 % selectivity to C-O bond ruptured products were achieved with similar to 21 % yield toward aromatics (benzene and phenol) on 0.5Ru1.5Fe/CeO2 catalyst. Characterization using X-ray photoelectron spectroscopy (XPS) and temperature programmed reduction (TPR) reveals that the adsorption of aromatic ring is weakened on the RuFe alloy surface compared to Ru which leads to reduced hydrogenation of arenes, while oxophilic nature of Fe facilitates the adsorption of the aryl-ether bond that enhances the hydrogenolysis of C-O bonds in DPE.

Advanced chemometric methods, such as fuzzy c-means, a semi-supervised clustering method, and fuzzy discriminant analysis, a robust supervised method, have been successfully applied for characterization and classification of 72 solvents according to the chemical parameters (P’ and x(i)) developed by Snyder. The obtained results (fuzzy partitions) and parameters of the prototypes (robust fuzzy means) clearly demonstrated the efficiency and information power of the advanced fuzzy methods in solvent characterization and classification, and allow a rationale choice of a good solvent or an efficient mixture of solvents in chromatography and other fields. Also, this methodology generates the premises for future investigations using other different properties of solvents.

Eighteen novel gemini quaternary ammonium compounds were synthesized to examine the effect of linker nature, aliphatic chain length and their relative position on antibacterial and antifungal activity. The synthesized compounds showed strong bacteriostatic activity against a panel of both Gram-positive and Gram-negative bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and two fungi. Some of these compounds exhibited a wider and more potent antimicrobial spectrum than commonly-used antiseptics, such as benzalkonium chloride (BAC), cetylpyridinium chloride (CPC), chlorhexidine digluconate (CHG) and octenidine dihydrochloride (OCT).
