Lemonile was manufactured by the dehydration of citral oxime obtained by the reaction of hydroxylamine sulfuride and citral abstracted from litsea cubeba oil. 從山蒼子提取出的檸檬醛,與硫酸羥胺反應(yīng)生成檸朦肟,脫水後可得到檸檬腈。
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. 用山蒼子油直接同硫酸羥胺反應(yīng)生成檸檬肟,再加入乙酐和相轉(zhuǎn)移催化劑脫水得到檸檬腈。
