Question

英语翻译
Production Of Crystalline Tribromostyrene
Field Of The Invention
It is an object of the invention to provide an improved method for the production of crystalline tribromostyrene
PRIOR ART
U.S.Pat.No.4,292,453,relates to the production of tribromostyrene using methylene chloride as solvent.U.S.Pat.No.4,423,262 relates to the production of dibromostyrene using t-BuOH.According to the former,tribromostyrene is not isolated from the reaction mixture in a crystalline form,and remains in a solution of CH.sub.2 Cl.sub.2.Its ultimate isolation from such solution results in poor yields.Another drawback is in the use of excess alkali (a ratio of NaOH to substrate of 5:1) and long reaction times--10 hours.

Answer 1

生产水晶Tribromostyrene
领域的发明
这是一个对象的发明提供一种改进方法,为生产水晶tribromostyrene
艺术之前,
美国.没有.4,292,453,涉及到生产的tribromostyrene使用二氯甲烷为溶剂.美国.没有.4,423,262涉及到生产的dibromostyrene t-BuOH使用.根据以往的,tribromostyrene不是孤立的,从反应混合物中,仍然是一个水晶体CH.sub.2 Cl.sub.2的溶液中.其最终结果等解决脱离贫困的产量.另一个缺陷是在使用过量碱(一种比中碱5:1)和长期的反应时间——10个小时.
