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). |
