Abstract

537,954. Adiponitrile. MAY, P. (Soc. des Usines Chimiques Rhone-Poulenc.). Aug. 29, 1939, No. 24821. [Class 2 (iii)] Adiponitrile is prepared by passing gaseous ammonia through molten adipic acid in the presence of orthophosphoric acid or an ester thereof. Examples are given of the use of the acid itself and of the tributyl tri-o-cresyl, tri-o-xenyl and di-o- or p-xenyl esters and a list of the other neutral and acid esters is included. Specification 477,463 is referred to.
