摘要： The present invention relates to a continuous process for the preparation of an aminonitrile comprising the stages of: a) formation of the aminonitrile by reaction between an alkenyl nitrile, mixed with aminonitrile, and a monoamine introduced in molar excess with respect to the alkenyl nitrile; b) separation of the unreacted monoamine and the aminonitrile; c) reaction between the monoamine separated during stage b) and all or part of the alkenyl nitrile in order to form a mixture of aminonitrile and of unreacted alkenyl nitrile, with the alkenyl nitrile being introduced in molar excess with respect to the said monoamine; d) transfer of the mixture of aminonitrile and alkenyl nitrile resulting from stage c) to the reaction of stage a), and e) in the case where only a portion of the alkenyl nitrile is introduced during stage c), introduction of the remaining molar amount of alkenyl nitrile into the mixture of stage d).
摘要翻译：本发明涉及一种用于制备氨腈的连续方法，包括以下步骤：a）通过与氨基腈混合的烯基腈与相对于烯基腈摩尔过量引入的单胺反应形成氨基腈; b）未反应的单胺和氨基腈的分离; c）在步骤b）期间分离的单胺与全部或部分链烯基腈之间的反应，以形成氨基腈和未反应的烯基腈的混合物，烯基腈相对于所述单胺以摩尔过量引入; d）从阶段c）得到的氨基腈和烯基腈的混合物转移到阶段a）的反应中，e）在步骤c）期间仅引入链烯基腈的一部分的情况下，引入剩余的摩尔烯基腈的量进入阶段d）的混合物中。
