本文对利用山苍子油中柠檬醛合成柠檬腈香料进行了新探和改进。

Abstract The synthesis of lemonile perfume from litsea cubeba oil is newly studied and re-formed .

对一步催化氨化法从柠檬醛合成柠檬腈进行了探讨，研究了氨与柠檬醛摩尔比、反应温度以及不同的催化剂对反应的影响。

New method for synthesizing Lemonile by catalytic ammoniation of citral was introduced . The influences of catalyst , ammonia flowrate , reacting temperature and the ammonia to citral ratio were investigated .

用山苍子油直接同硫酸羟胺反应生成柠檬肟，再加入乙酐和相转移催化剂脱水得到柠檬腈。

Litsea cubeba oil reacted with hydroxylamine sulfate to give citral oxime , which by dehydration with acetic anhydride in the presence of phase transfer catalyst gave lemonile .

从山苍子提取出的柠檬醛，与硫酸羟胺反应生成柠朦肟，脱水后可得到柠檬腈。

Lemonile was manufactured by the dehydration of citral oxime obtained by the reaction of hydroxylamine sulfuride and citral abstracted from litsea cubeba oil .
