尿素氨化制备歧化松香腈的研究

STUDIES ON PREPARATION OF DISPROPORTIONA-TED ROSIN NITRILE BY UREA AMMONIFICATION

以歧化松香为原料 ,在氯化钴和硼酸催化作用下 ,用尿素氨化 ,制得了歧化松香腈 ,以歧化松香计 ,歧化松香腈的收率为 83.3%。讨论了原料比、催化剂、反应温度、反应时间等因素对反应的影响。

Disproportionated rosin nitrile was prepared via ammonification of disproportionated rosin with urea in the presence of catalyst cobalt chloride and boronic acid The yield of disproportionated rosin nitrile is 83 3% Effect of the ratio of reaction substance, the amount of catalyst, reaction temperature, reaction time is discussed.
