The invention relates to a process for preparing succinonitrile by contacting acrylonitrile (ACN) with hydrocyanic acid (HCN) in a reactor in the presence of a tertiary amine. The invention also relates to the use of succinonitrile prepared according to the process of the invention, for preparing diaminobutane. Succinonitrile is prepared by contacting ACN with HCN in the presence of a tertiary amine and a compound chosen from the group consisting of aliphatic alcohols, water and mixtures thereof.
本发明涉及一种制备琥珀腈的工艺,其方法是在有叔胺存在的情况下,在反应器中使丙烯腈(ACN)与氢氰酸(HCN)接触。本发明还涉及根据本发明工艺制备的琥珀腈在制备二氨基丁烷中的用途。琥珀腈是在叔胺和一种选自脂肪醇、水及其混合物的化合物的存在下,通过使 ACN 与 HCN 接触而制备的。
