Production of nitrile compounds

The invention relates to a method for producing nitrile compounds by chain extension of an alkylene amine compound containing three or more amine units, in which at least two amine units are protected by cyclic urea units and at least one amine unit is not protected, the at least one unprotected amine unit is reacted with glycolonitrile or with a combination of formaldehyde and a cyanide selected from HCN and inorganic cyanide salts to add at least one acetonitrile group to the at least one unprotected amine unit. The method according to the present invention allows the production of nitrile compounds with high selectivity and high yield. The nitrile compound can be processed as required. 本发明涉及一种通过含有三个或更多个胺单元的亚烷基胺化合物的扩链来制造腈化合物的方法，其中至少两个胺单元被环状脲单元保护并且至少一个胺单元未被保护，做法是，使所述至少一个未被保护的胺单元与乙醇腈或与甲醛和选自HCN和无机氰化物盐的氰化物的组合反应，以将至少一个乙腈基团添加至所述至少一个未被保护的胺单元。根据本发明的方法允许以高选择性和高产率制造腈化合物。所述腈化合物可以根据需要进行加工。
