摘要： The present invention relates to a process for the manufacture of dinitrile compounds by double hydrocyanation of an olefin.It relates particularly to a process for the manufacture of dinitrile compounds by double hydrocyanation of an olefin present in a mixture of hydrocarbons, such as a petroleum fraction and more particularly still a petroleum fraction known under the name of C4 fraction.The process of the invention comprises a sequence of stages for the separation of the various compounds which makes it possible to remove the byproducts, such as the products from the trimerization of alkynes, present in the C4 fraction and thus to prevent their accumulation in the hydrocyanation reactors.
摘要翻译：本发明涉及通过烯烃的双氢氰化生产二腈化合物的方法。特别涉及通过双酚氢化存在于烃混合物中的烯烃（例如石油馏分，更特别是C4馏分已知的石油馏分）来制备二腈化合物的方法。本发明的方法包括用于分离各种化合物的一系列阶段，这使得可以除去存在于C4馏分中的副产物，例如来自炔烃三聚的产物，从而防止其在氢氰化中的积累反应堆。
