Abstract
1368398 Benzyl cyanide FARBWERKE HOECHST AG 19 July 1972 [19 July 1971] 33808/72 Heading C2C Benzyl cyanide is produced by reacting hydrogen cyanide and a carboxylic acid ester of benzylalcohol in the gas phase in the presence of a catalyst comprising a copper (II) salt. Preferably the reaction is carried out at elevated temperature in the presence of a copper (II) halide, nitrate, cyanide, sulphate or acetate, the ester is derived from a carboxylic acid having up to 10 carbon atoms, especially acetic acid, and the product is cooled and condensed on leaving the reactor. The reaction gas stream may comprise, or be alternated with a volatile inert substance, e.g. nitrogen, or an additive, e.g. hydrogen halide, and/or water and/or O 2 or a free-O 2 containing gas or the reaction may be carried out in a fixed, moving or fluid bed. The catalyst may also comprise a Lewis acid and be supported on a carrier, e.g. SiO 2 , Al 2 O 3 , active carbon, ZrO 2 , aluminium silicate or molecular sieve.
