    • The present invention provides a process for producing a nitrile represented by the general formula (1):RC.ident.N (1)wherein R is alkyl, alkenyl, aralkyl or aryl, each may have a substituent, characterized by heating an aldoxime represented by the general formula (2):RCH=NOH (2)wherein R is as defined above, in the presence of one or more catalysts selected from hydroxides of alkali metals, alcoholates of alkali metals, hydroxides of alkaline earth metals and alcoholates of alkaline earth metals, and distilling off water formed in the course of the reaction from the reaction system. The process according to the present invention can produce a nitrile which is useful as a perfume or as a starting material for the organic synthesis of perfumes, medicines and so on in high yields and advantageously from the viewpoint of production economy.
    • 本发明提供一种制备由通式(1)表示的腈的方法:RC = N(1)其中R是烷基,烯基,芳烷基或芳基,各自可以具有取代基,其特征在于加热由 在一种或多种选自碱金属的氢氧化物,碱金属的醇化物,碱土金属的氢氧化物和碱土金属的醇化物的催化剂的存在下,通式(2):RCH = NOH(2)其中R的定义同上 ,并从反应体系中蒸馏出在反应过程中形成的水​​。 根据本发明的方法可以产生腈,其可以作为香料或用作有机合成香料,药物等的高产率的有机合成起始材料,并且从生产经济性的观点来看是有利的。
