The present invention provides a method for producing an N-substituted carbamic acid ester, a composition for transportation and storage containing the N-substituted carbamic acid ester, and a method for producing an isocyanate by thermal decomposition of the compound. A composition comprising an N-substituted carbamic acid ester, a carbonic acid derivative, and one or more hydroxy compounds from an organic amine, a carbonic acid derivative, and a hydroxy composition comprising one or more hydroxy compounds. And then pyrolyzing the composition to produce the corresponding isocyanate. [Selection figure] None |
