Abstract: 1-Alkenyl isocyanates are prepared by reacting aldehydes with carbamates to give N-(1-alkenyl)-carbamates and splitting these compounds at elevated temperatures. The 1,2-unsaturated isocyanates obtained are valuable starting materials for the preparation of pest control agents, dyes, drugs, textile water repellents, detergents, plastics, bleaches and adhesives, since they possess an activated double bond or an activated alpha -carbon atom, in addition to a reactive isocyanate group.

Abstract: Prepn. of ethylene cyanhydrin comprises reacting water with acrylonitrile in the presence of quat. ammonium hydroxides as catalyst and HCHO. The resulting reaction mixt. can be hydrogenated with H2 in the presence of ammonia and hydrogenation catalysts without sepg. the ethylene cyanhydrin, to give 3-aminopropanol-(1) in good yields. Ethylene cyanhydrin, is an important intermediate in the prepn. of solvents, e.g. for cellulose lacquers, dyestuffs plant protection agents, pharmaceuticals and plastics. It is also a starting material for the prepn. of plasticisers for PVC or the extraction of aromatics from crude oil.
