Abstract (en)
[origin: WO9619439A1] The present invention relates to a process for producing pentene-nitriles. The pentene-nitriles, more particularly 3-pentene-nitrile and 4-pentene-nitrile, may give adiponitrile by reaction with hydrogen cyanide. More particularly, the invention relates to a process for preparing pentene-nitriles by implementing in vapor phase 2-methylglutarimide or ethylsuccinimide in the presence of a solid acid catalyst. 2-methylglutarimide may be implemented directly or in the form of one of the precursors thereof, such as particularly 4-cyanovaleramide, 2-methyl 4-cyanobutyramide, 4-cyanovaleric acid, 2-methyl 4-cyanobutyric acid. Likewise, ethylsuccinimide may be implemented directly or in the form of one of the precursors thereof, such as particularly 3-cyanovaleramide, 2-ethyl 3-cyanopropionamide, 3-cyanovaleric acid, 2-ethyl 3-cyanopropionic acid.
