PROCESS FOR THE PREPARATION OF N-SUBSTITUTED CARBAMIC ACID ESTER AND PROCESS FOR THE PREPARATION OF ISOCYANATE USING THE N-SUBSTITUTED CARBAMIC ACID ESTER

The present invention provides a method for producing N-substituted carbamic acid-O-aryl ester derived from a compound having an ureido group, the method comprising the step of carrying out esterification or esterification and transesterification from the compound having the ureido group and a hydroxy composition containing one type or a plurality of types of hydroxy compounds.

Process for the preparation of N,O-disubstituted urethanes suitable as a starting material for the preparation of isocyanates

A process for the preparation of N,O-disubstituted urethanes. Primary amines and alcohols are reacted with organic compounds having carbonyl groups at 120° to 350° C. Suitable carbonyl-containing compounds include N-unsubstituted urethanes. N-mono-substituted, N,N'-disubstituted ureas, or polyureas may be used in combination with the N-unsubstituted urethane. The product urethanes are particularly suitable for the preparation of isocyanates.
