A theoretical and experimental study is performed for liquid-solid phase equilibria in the two-component diphenyl oxide-n-hexadecane system. The results show that this system is eutectic. Two means are chosen for the theoretical study of the system: the Schroder-Le Chatelier equations and the original UNIFAC system. Experimental studies are made via differential thermal analysis on a DSC unit. Results from the theoretical and experimental studies are presented in the formT-xdiagrams of the system. The theoretical and experimental data are compared to one another. Each way of calculating is assessed, and recommendations are made for their application. The eutectic coordinates (melting point and composition) are determined experimentally. The following values are determined experimentally for a eutectic melt: the enthalpy of melting; density at 25 degrees C; kinematic viscosity in the temperature range of 25 to 50 degrees C; flash point in an open cup; boiling point, and refractive index in the temperature range of 25 to 40 degrees C. The composition of the eutectic melt can be used in industry as a heat transfer fluid.

The increasing risk of fossil fuels depletion due to surging energy demand has accelerated the search of alternative renewable sources. Lignin, one of the major components of lignocellulosic biomass, is the only abundant renewable natural resource for aromatic compounds. In this work, the effects of metals and process parameters were discussed via the catalytic hydrogenolysis of beta-O-4 lignin model compound, 2-phenethyl phenyl ether. The best results were obtained over Rh/Nb2O5 with an overall conversion of 99.3% and exceptional selectivity of 98.9% to aromatic products when the hydrogenolysis was carried out at 260 degrees C and 0.1 MPa H-2 for 4 h. The high efficiency is mainly attributed to the cooperation between Rh and NbOx at the perimeter sites, in which Rh particles are responsible for the dissociation of H-2 and NbOx for activating CeO bonds. With respect to depolymerize of ash wood lignin, the liquid products were mostly aromatics over Rh/Nb2O5 under 0.1 MPa H-2. The results achieved in this work provide a promising prospect towards valorization of lignin into production of valuable aromatic compounds under low hydrogen pressure.

Lignin is constructed from methoxylated phenylpropanoid with plenty of hydroxys and methoxys. Its conversion to valuable products is extremely attractive but especially challenging without additional hydrogen sources. Herein we report a hydrogen-free production of 4-alkylphenols directly from native lignin via self-reforming-driven depolymerization and hydrogenolysis over Pt/NiAl2O4. This is the first example of acquiring 4-alkylphenols from native lignin. Using this strategy, high yields of 4-alkylphenols, 17.3 wt %, were obtained from birch lignin. Reaction pathway and mechanism studies revealed that this strategy initiates from the reforming of aliphatic hydroxys, followed by the cleavage of C-O linkages, and ends via demethoxylation over Pt/NiAl2O4. Moreover, the subsequent aqueous phase reforming of the as-formed methanol accelerates the whole process. This strategy realizes the one-pot production of 4-alkylphenols from lignin by fully utilizing the structural hydrogen in lignin and H2O, providing a low-cost and safe method of lignin valorization.

Toward a more rigorous inspection of food contact materials, the importance of sample preparation for nontarget screening should be addressed. Direct immersion-solid-phase microextraction coupled to gas chromatography mass spectrometry (DI-SPME-GC-MS) was optimized for nontarget screening of migrants in 3% acetic acid, 10% ethanol, and 95% ethanol food simulants by response surface methodology (RSM) in the present study. Optimum conditions were DVB/CAR/PDMS fiber, no pH adjustment for 10% and 95% ethanol simulant but pH adjustment to 7 for 3% acetic acid simulant, no salt addition, 5 min preincubation, 55 min extraction at 70 degrees C, and 8 min desorption at 250 degrees C. In addition, 9.5 times dilution of 95% ethanol samples prior to extraction was required. pH modification of 3% acetic acid samples was found to be critical for the extraction of amines. The proposed methodology was then evaluated by determining the limit of detection (LOD) as well as repeatability of 35 food contact materials-related substances. Except for those amines and diols which have a relatively high LOD, the LODs of the rest of the substances were 0.1-14.1 mu g/kg with a precision of 1.9-23.0% in 10% ethanol and were 0.1-20.2 mu g/kg with a precision of 2.5-19.6% in 3% acetic acid simulant. The LOD and precision in 95% ethanol simulant were 0.7-163.7 mu g/kg and 1.4-26.8%, respectively. The proposed method can be applied for an overall screening of migrants from these three simulants at even trace levels, though attention should be paid to some specific analytes, e.g., diols and amines, which could have a high LOD and toxicity.

HPLC of Formula: C12H10O. I found the field of Environmental Sciences & Ecology very interesting. Saw the article Mechanisms and pathways of debromination of polybrominated diphenyl ethers (PBDEs) in various nano-zerovalent iron-based bimetallic systems published in 2019.0, Reprint Addresses Lu, GN; Dang, Z (corresponding author), South China Univ Technol, Sch Environm & Energy, Guangzhou 510006, Guangdong, Peoples R China..

This study investigated the relative significance of electron transfer (e-transfer) and H-atom transfer (H-transfer) in a nanoscale zerovalent iron (n-ZVI) system and six n-ZVI-based bimetallic systems (Fe/Cu, Fe/Ni, Fe/Pd, Fe/Ag, Fe/Pt, and Fe/Au) through a case study of the debromination of 2,2′, 4,4′-tetrabromodiphenyl ether (BDE-47). The results revealed that the reactivities of these bimetallic particles to BDE-47 decreased in the following order: Fe/Pd > Fe/Ag > Fe/Cu > Fe/Ni > Fe/Au > Fe/Pt approximate to n-ZVI. Debromination of BDE-47 in metal-H2 systems suggested that Ni, Pd, Pt, Cu and Au can utilize H-2 to debrominate BDE-47. In the H-transfer process, BDE-47 preferentially debrominated the para-bromine substituent to generate BDE-17, whereas in the e-transfer process, BDE-47 preferentially debrominate ortho-bromine substituent to generate BDE-28. The debromination pathways of BDE-47 in bimetallic and NaBH4-metal systems suggested that Fe/Ni, Fe/Pd and Fe/Pt debrominate polybrominated diphenyl ethers (PBDEs) through a H-transfer dominant mechanism, while Fe/Ag debrominate PBDEs through an e-transfer dominant mechanism. In the cases of Fe/Cu and Fe/Au, the e-transfer and H-transfer may be equally involved in the debromination of PBDEs. These results greatly improve our understanding of the relative significance of e-transfer and H-transfer in the dehalogenation of halogenated aromatic compounds (HACs) in various n-ZVI-based bimetallic systems.

Nanoparticles layered with palladium(0) were prepared from nano-sized magnetic Fe3O4 by coating it with silica and then reacting sequentially with phenylselenyl chloride under an N-2 atmosphere and palladium(ii) chloride in water. The resulting Fe3O4@SiO2@SePh@Pd(0) NPs are magnetically retrievable and the first example of NPs in which the outermost layer of Pd(0) is mainly held by selenium. The weight percentage of Pd in the NPs was found to be 1.96 by ICP-AES. The NPs were authenticated via TEM, SEM-EDX, XPS, and powder XRD and found to be efficient as catalysts for the C-O and C-C (Suzuki-Miyaura) coupling reactions of ArBr/Cl in water. The oxidation state of Pd in the NPs having size distribution from similar to 12 to 18 nm was inferred as zero by XPS. They can be recycled more than seven times. The main features of the proposed protocols are their mild reaction conditions, simplicity, and efficiency as the catalyst can be separated easily from the reaction mixture by an external magnet and reused for a new reaction cycle. The optimum loading (in mol% of Pd) was found to be 0.1-1.0 and 0.01-1.0 for O-arylation and Suzuki-Miyaura coupling, respectively. For ArCl, the required amount of NPs was more as compared to that needed for ArBr. The nature of catalysis is largely heterogeneous.

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).

Rationale Recently, we have reported a forced degradation study of a pharmaceutical drug regorafenib which contains a phenyl pyridyl ether derivative as building block. We observed interesting rearrangements in two of its degradation products in tandem mass spectrometry (MS/MS) experiments. As diphenyl ether derivatives are also molecular building blocks of biological importance and used as herbicides and flame retardants, we decided to investigate specifically the fragmentation behavior of these compounds along with phenyl pyridyl derivatives in detail using high-resolution electrospray ionization (ESI) MS/MS. Methods To understand the fragmentation reactions of protonated substituted diphenyl ethers and phenyl pyridyl ethers, ESI-MS/MS experiments were performed using a quadrupole time-of-flight (QTOF) mass spectrometer. Results In contrast to radical cations of diphenyl ether derivatives which do not eliminate CO, the [M + H](+) ions of substituted diphenyl ethers undergo rearrangement reactions after loss of neutral molecules (H2O, HCl, etc.) to form a bicyclic structure containing a keto group and do eliminate CO. Similar rearrangement followed by fragmentation was observed for protonated phenyl pyridyl ethers and the degradation products formed from regorafenib and sorafenib. Conclusions The protonated ions of substituted diphenyl ethers and phenyl pyridyl ethers on collision-induced dissociation have exhibited interesting rearrangement reactions, despite the nature of the substituent on both the aryl moieties. The proposed fragmentation patterns of these compounds give an insight into the understanding of gas-phase reactions in mass spectrometric studies of diphenyl ether and phenyl pyridyl ether derivatives.

The classical Sonogashira reaction of aryl electrophiles in the presence of Pd catalysts has been well established as a potent method for arylalkyne synthesis. However, the site-selective C(sp(2))-C(sp) cross-coupling strategy using a non-noble-metal catalyst is rare. An efficient alternative approach for the synthesis of arylalkynes via a Cu-catalyzed Sonogashira-type reaction promoted by visible light is described. This method enables site-selective alkynylation from aryl sulfonium salts derived from diverse arenes to a set of arylalkynes with high selectivity and high functional-group compatibility. Moreover, rapid alkynylation of drug molecules is demonstrated.
