Abstract
The carbamates are prepared by reacting lower aliphatic carbamates with higher-boiling alcohols. Reaction is carried out in the presence of alkyl titanates as catalyst, with heating. The low molecular weight alcohols formed are distilled continuously from the reaction mixture. By using the alkyl titanates as catalyst, reaction times are greatly reduced.
