手译也有水平高低之分。我首先可以保证此文语法没有错误,可放心使用。有关有机化学词汇也译出,只有“氯代特戊酰氯找到化学分子式”,只好暂时用上,请予以更正。同时怀疑原文中的“邻氯苄氯”实为“邻氯氯苄”,请查对,目前是按后者译的。想当初,我还是中学化学科代表,甚至还报考了高分子化学!终因服从入学分配阴差阳错而走上了专业翻译的道路。化学方面还得多向你请教。Abstract: 2-(2-chlorobenzene C6H5Cl) cymene-4, 4- cymene-3-isoxazolones, widely known as Clomazone in English or Guangmieling in Chinese, is a herbicide with a nitric heterocyclic structure that has extensive applications in agricultural production. This article is mainly an introduction to the route for synthesizing this compound and the method of its , ClCH2(CH3)2COCl reacts with hydroxylamine hydrochloride in water solvent, producing 3-chlorin-N-hydroxid-2, 2-dimethyl propionamide. During the reaction process, drops of a 50% sodium hydroxide solution are applied to control the Ph rate. Then, 3-chlorin-N-hydroxid-2, 2-dimethyl propionamide form a cycle under the stimulation of sodium hydroxide, resulting in a five-element heterocycle that contains nitrogen and oxygen, ., 4, 4-dimethyl-3-isoxazolones. Finally, 4, 4-dimethyl-3-isoxazolones and 2-chlorobenzyl chloride produce, through condensation reaction, 2-[(2-chlorobenzene) methyl]-4,4-dimethyl-3-isoxazolones as well as isomer impurities. To obtain products of higher purity, we refine them through the introduction of dried hydrogen chloride. The share of the target product has been increased through such experiments.关键词:广灭灵 合成 杂环 提纯 Key words: Guangmieling, clomazone, synthesis, heterocycle, purification
