The present invention relates to a process for the manufacture of compounds comprising two nitrile functional groups. It relates more particularly to a process for the manufacture of dinitrile compounds from compounds comprising a nitrile functional group and an ethylenic unsaturation in the presence of a catalytic system comprising an organometallic complex and a cocatalyst of the Lewis acid type. The process of the invention comprises a stage of treatment of the reaction medium resulting from the hydrocyanation which makes it possible to extract and recover the metal element of the Lewis acid.
本发明涉及一种制备含有两个腈官能团的化合物的方法。更具体地,涉及一种在存在包括一个有机
金属配合物和一种Lewis酸类辅助催化剂的催化系统的情况下,从含有腈官能团和
乙烯不饱和度的化合物制备二腈化合物的方法。本发明的方法包括处理由氢
氰化反应产生的反应介质的阶段,该阶段使得能够提取和回收Lewis酸的
金属元素。
