Abstract

Phenyl isocyanate reacts with ethyl alcohol at 125” to give a 22.9% yield of ethyl a, y- diphenylallophanate and a trace of phenyl isocyanate dimer. When N-methylmorpholine is added as a catalyst, the reaction is altered and the product is triphenylisocyanurate (isocyanate trimer) in excellent yield. Phenyl isocyanate without the ethyl alcohol and heated under the same conditions in the presence of N-rnethylrnorpholine yields only a small ...
