Abstract:
A process in which a metal carbamate, especially an N-mono- or N-di-hydrocarbaryl carbamic acid metal salt, is combined with an ester or amide of a carboxylic acid to produce a metal carboxylate and a urea or an ester of a carbamic acid. The carbamate esters of acidic hydroxyl compounds, usually phenolics, can further decompose to the corresponding phenol and isocyanate, or, the carbamate ester may be combined with ammonia, a primary amine or secondary amine to produce the corresponding hydroxylated hydrocarbaryl and urea. A variation includes transesterification-metallation between carboxylate esters and metal salts of carboxylic acids.
