ISOCYANATE PRODUCTION PROCESS USING COMPOSITION CONTAINING CARBAMIC ACID ESTER AND AROMATIC HYDROXY COMPOUND, AND COMPOSITION FOR TRANSFER AND STORAGE OF CARBAMIC ACID ESTER

摘要

Disclosed are: a method for producing an isocyanate by using a composition comprising a carbamic acid ester and an aromatic hydroxy compound, which does not need to use any phosgene and does not have various problems accompanied by a conventional method for the production of an isocyanate; and a carbamic acid ester composition for the transport or storage of a carbamic acid ester. Specifically disclosed are: a method for producing an isocyanate, which involves a specific step and uses a composition comprising a carbamic acid ester and a specific aromatic hydroxy compound; and a composition for the transport or storage of a carbamic acid ester, which comprises a carbamic acid ester and a specific aromatic hydroxy compound.
