Abstract: Acrylonitrile is prepared by reacting a mixture of propylene, ammonia and oxygen in the vapour phase in the presence of a bismuth, tin or antimony salt of molybdic or phosphomolybdic acid or bismuth phosphotungstate and in the presence of added hydrogen cyanide in amount 0.01-0.2, preferably about 0.1, moles per mole of propylene. Water may be present in the vapour phase reaction medium. Preferably at least part of the hydrogen cyanide separated from the reaction products is recycled. Specification 867,438 is referred to.

Abstract: C1-4 alkyl acrylates or methacrylates are prepared by contacting in the vapour phase at 400 DEG to 800 DEG F., a mixture of a C1-4 alkanol, acrylonitrile or methacrylonitrile, and water with a solid esterification catalyst, the molar ratio of water to nitrile being at least 1:1. Specified catalysts are silica gel, silica, silica alumina, titania, zirconia and thoria. Metal promoters or phosphoric or molybdic acids may be added. Water/nitrile ratios of up to about 5:1 are mentioned. The process may be operated with fixed or fluidized catalyst beds; in the latter case, continuous regeneration may be effected. The products may be recovered by, for example, water scrubbing. Unreacted feed materials may be recycled.
