    • The present invention relates to a process for the hydrocyanation of unsaturated compounds to unsaturated mononitrile compounds or to dinitrile compounds; It relates more particularly to a process for the manufacture of dinitriles by double hydrocyanation of diolefins, such as butadiene, comprising a recovery and separation of the catalytic system. The process for the manufacture of dinitriles of the invention by hydrocyanation of unsaturated compounds, comprising at least one stage of hydrocyanation in the presence of a catalytic system comprising an organometallic complex formed by one or more monodentate organophosphite ligands and one or more bidentate organophosphorus ligands and optionally a promoter of Lewis acid type, comprises at least one stage of separation by distillation of a reactant used in the process or of a compound formed by the reaction from a medium comprising the said catalytic system.
    • 本发明涉及不饱和化合物氢化成不饱和单腈化合物或二腈化合物的方法; 更具体地涉及通过二烯烃如丁二烯的双氢氰化制备二腈的方法,其包括催化体系的回收和分离。 通过氢化不饱和化合物的方法制备本发明的二腈的方法,该方法在包含由一个或多个单齿有机亚磷酸酯配体和一个或多个二齿有机磷配体形成的有机金属络合物的催化体系存在下包含至少一个氢化氰化阶段,以及 任选的路易斯酸型助催化剂包括通过蒸馏在该方法中使用的反应物或由包含所述催化体系的介质通过反应形成的化合物的至少一个阶段进行分离。
