Evaluating the efficacy of a newly developed palm-based process aid on nitrile rubber composites

The exploration of bio-based process aid is still ongoing in the effort to replace petroleum-based process oil. In this study, the efficacy of a newly developed palm-based process aid (Bio) on nitrile rubber (NBR) composites was investigated by varying its concentration from 0.0 to 10.0 phr. A comparison was made against a commercial oil (CO), i.e. naphthenic oil in terms of Mooney viscosity, cure characteristics, morphology, physical, and chemical properties. Results revealed that the use of Bio as process aid improves the processability of rubber by lowering the Mooney viscosity, enhancing filler dispersion, and lowering loss tangent values. Tensile properties and compression sets of CO-NBR composites were slightly better compared to Bio-NBR composites. Interestingly, Bio-NBR composites showed better ageing properties, especially at higher process aid content. Higher retentions of tensile strength and elongation at break and lower compression sets of aged Bio-NBR compared to CO-NBR composites were observed, which are possibly contributed by the good compatibility of Bio with aged rubber. Thermogravimetric analysis showed that the thermal stability of Bio-NBR composites were slightly better than CO-NBR composites. Based on these findings, the use of Bio (>= 7.5 phr) as process aid significantly improved the processability of rubber with some enhancement in ageing properties of composites that is desirable and ideal for various applications such as for the production of automotive components.

Synthetic Processes toward Nitriles without the Use of Cyanide: A Biocatalytic Concept Based on Dehydration of Aldoximes in Water

While belonging to the most fundamental functional groups, nitriles represent a class of compound that still raises challenges in terms of an efficient, cost-effective, general and, at the same time, sustainable way for their synthesis. Complementing existing chemical routes, recently a cyanide-free enzymatic process technology based on the use of an aldoxime dehydratase (Oxd) as a biocatalyst component has been developed and successfully applied for the synthesis of a range of nitrile products. In these biotransformations, the Oxd enzymes catalyze the dehydration of aldoximes as readily available substrates to the nitrile products. Herein, these developments with such enzymes are summarized, with a strong focus on synthetic applications. It is demonstrated that this biocatalytic technology has the potential to cross the bridge between the production of fine chemicals and pharmaceuticals, on one hand, and bulk and commodity chemicals, on the other.

Anion polarity-induced self-doping in a purely organic paramagnetic conductor, alpha ‘-alpha ‘-(BEDT-TTF)(2)(PO-CONH-m-C6H4SO3)center dot H2O where BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene and PO is the radical 2,2,5,5-Tetramethy1-3-pyrrolin-1-oxyl

A new BEDT-TTF-based salt with an organic free radical, alpha’-alpha’-(BEDT-TTF)(2)(PO-CONH-m-C6H4SO3)center dot H2O, has been prepared. The crystal structure consists of alternating donor and anion/water layers propagated along the c axis. The anisotropic radical anions form a head-to-head arrangement, which provides a permanent dipole moment. The effect on the nearest donor layer has been estimated to be 4.0 V. The salt has two crystallographically independent donor layers (A and B), one of which (A) is surrounded by the negative ends of the anion layer dipole whereas the B layers are bordered by the positive ends of the dipole. This structural feature suggests that layers A and B have different Fermi levels. To eliminate the imbalance, self-doping occurs whereby electron density is transferred from layer A to B. The temperature dependence of the magnetic susceptibility has 11.1% of extra Curie spins, from which a doping ratio of 12.7% has been estimated. (c) 2017 Elsevier Ltd. All rights reserved.

Synthesis and herbicidal activity of novel 3-alkoxycarbonyl-3-aryl-2, 3-dihydro-2-oxo-1H-pyrrole derivatives

In the course of efforts to find novel compounds with improved crop safety in transplanted rice by the modification of 1-[1-(3,5 -dichlorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (1a), which was reported to have excellent herbicidal activity against paddy weeds, 2,3-dihydro-2-oxo-1H-pyrrole derivatives with a quaternary carbon atom having an alkoxycarbonyl group at the alpha-position of the cyclic amide were synthesized and examined. Among these compounds, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate (2a) was not only active against Echinochloa oryzicola and Scirpus juncoides but also compatible with transplanted rice even in harsh conditions. On the bask of Preliminary experimental results. it was thought that 2a would generate the corresponding 2-oxo-3-pyrrolin (la) through the metabolic degradation of the methoxycarbonyl moiety.

Methylenimine and cyanomethanimine synthesis from ion irradiation of N-2-CH4 ice: Implication on the formation of prebiotic molecules in outer solar system bodies

The synthesis of methylenimine and cyanomethanimine from ion irradiation of N-2-CH4 ice was studied, in an attempt to simulate the role of medium mass cosmic rays and energetic solar particles in the processing of nitrogen-rich ices on cold astrophysical environments, such as those in the outer region of the solar system (e.g. Pluto, Charon, Triton, Makemake and Titan). The N-2-CH4 (90:10) ice mixture was irradiated at 9 K by 38.4 MeV Ca-40(9+) (0.96 MeV/u) at the GANIL facility (Caen/Fance). The evolution of the samples was monitored using insitu Fourier transform infrared spectroscopy (FTIR). The results indicate the formation of CH2NH and CH2NCN, which are considered species of interest in prebiotic chemistry. Other species produced by radiolysis were HCN, HNC, hydrocarbons and nitriles. Direct comparison of the laboratory spectrum from the mixture of reaction products provides an efficient way to focus on the identification of chemical synthesis routes for the production of molecules important in the development of life that are consistent with the chemical inventory and physical conditions on frozen moons and cold objects in the outer solar system.

Synthesis of a fluorinated derivative of sigma-1 receptor modulator E1R: 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide

The ozonation of N-Boc-protected 3-methylidene-4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one resulted in its transformation into 3-hydroxy4-phenyl-5-(trifluoromethyl)-3-pyrrolin-2-one. Catalytic hydrogenation of its O-Boc-protected derivative introduced a way to reduce the double bond in combination with elimination of the hydroxy group leading to the formation of 4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one as an intermediate in the synthesis of fluorinated E1R structural derivative 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide.
