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 compositio n comprising a carbamic acid ester and an aromatic hydroxy compound, which d oes not need to use any phosgene and does not have various problems accompan ied by a conventional method for the production of an isocyanate; and a carb amic acid ester composition for the transport or storage of a carbamic acid ester. Specifically disclosed are: a method for producing an isocyanate, whi ch involves a specific step and uses a composition comprising a carbamic aci d ester and a specific aromatic hydroxy compound; and a composition for the transport or storage of a carbamic acid ester, which comprises a carbamic ac id ester and a specific aromatic hydroxy compound.
