Abstract

1464788 Carbamate preparation UNION CARBIDE CORP 16 Dec 1974 [27 Dec 1973] 54252/74 Heading C2C Carbamates are prepared by reacting an organic compound having at least one isocyanate group with an organic compound having at least one hydroxyl group in the presence of an anionic cation exchange resin having free tertiary amino and/or quaternary ammonium functional groups not in their pyridine form, a sufficient number of which are in their hydroxy form to effect the reaction producing carbamate compounds.
