标题:普通高能官能团取代的十二烷的辐射降解
摘要:炸药存在于并有望承受各种恶劣环境,包括电离辐射,但人们对将炸药暴露于电离辐射场的化学后果知之甚少.这项研究的重点是通过利用一致的分子主链,辐射诱导的各种常见高能官能团的化学变化.十二烷被叠氮化物,硝基,硝酸酯和硝胺官能团取代,并用60Co 为了研究官能团如何降解以及对电离辐射的相对稳定性是什么.使用分析技术的组合评估化学变化,包括:核磁共振 (NMR) 光谱,凝聚相和气相的气相色谱,拉曼光谱和傅里叶变换红外 (Ftir) 光谱.结果表明,对分子的大部分损伤都发生在高能官能团上,并且通常集中在触发键上,也称为分子中最弱的键.发现从最易受辐射损伤到最不易受辐射损伤的总趋势是 D-ono 2-> D-n 3-> D-nhno 2-> D-no 2. 这些结果似乎也符合这些官能团对光解,热解和爆炸性侮辱等事物的相对稳定性.

摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

标 题 :Sequential and independent synthesis of mercaptans and asymmetrical sulfides in a single reactor
发明人：LASSEN KENNETH M; NWAGWU UGOCHUKWU; HASENBERG DANIEL M
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:The present disclosure generally relates to processes to produce a mercaptan and an asymmetrical sulfide utilize stacked bed catalyst systems containing CoMo and NiMo, and these processes demonstrate a synergistic reduction in the amount of ethylene, methyl mercaptan, ethyl mercaptan, and H2S in product mixtures. In aspects, the conversion of limiting reactants in the synthesis of asymmetrical sulfides unexpectedly remain high under increased flow rates through the catalyst bed, and under reduced temperatures and pressures. In further aspects, reactor systems configured for the independent synthesis of mercaptans and asymmetrical sulfides in a single fixed bed catalyst vessel are also disclosed as a simplification of existing reactor systems employing separate reactors for separate mercaptan and sulfide syntheses.

摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.
