摘要: Catalyst composition for the dimerization of acrylonitrile comprising an organo-phosphorus compound of formula ##STR1## bonded to a matrix of an inorganic oxide having surface --OH groups, especially of silica or alumina. Groups R and Y are hydrocarbyl. The catalyst compositions are prepared by heating the matrix with an appropriate phosphorus compound having group(s) X which react with --OH groups with the elimination of HX. The invention also relates to a process for the dimerization of acrylonitrile. Main products are 1,4-dicyanobutene-1 and 2-methylene glutaronitrile.
