Abstract

1307414 Recovering acrylonitrile STAMICARBON NV 3 June 1970 [11 June 1969] 26845/70 Heading C2C [Also in Division C1] Acrylonitrile is recovered from an aqueous ammonium salt solution which has been obtained by cooling hot reaction gases from an acrylonitrile synthesis by direct contact with a mineral acid containing aqueous-solution, and which is contaminated by a small proportion of acrylonitrile, by distilling or stripping the aqueous ammonium salt solution in a distillation column wherein the bottoms temperature is kept below 100‹ C., and removing overhead acrylonitrile vapours.
