溴菌腈中间体2-亚甲戊二腈的合成最佳条件探讨(英文)

Studies on the Optimum Technological Condition for Synthesis of 2-Methylene Glutaronitrile(MGN),a Intermediate of Fungicide Bromothalonil

在二元催化剂下,进行了催化剂和原料配比、反应温度、反应时间对溴菌腈合成所需关键的中间体MGN收率影响的试验,提出了最佳反应状态的工艺条件为催化剂与原料的配比为1:4.8,反应温度为28℃,反应时间为8～9 h。

Effect of catalyst, charge ratio of raw materia, reaction temperature and reaction time on yield of synthesizing key intermediate MGN of bromothalonil was studied. The optimum technological condition was put forward.
