Document Type and Number:
Japanese Patent JP2012153708
Kind Code:
A
Abstract:
To provide a method for producing N-substituted carbamic ester, a composition for transfer and storage containing the N-substituted carbamic ester, and a method for producing isocyanate by thermal decomposition of the compound.
A composition containing N-substituted carbamic ester, a carbonic acid derivative, and one or a plurality of kinds of hydroxy compounds is prepared from organic amine, a carbonic acid derivative, and a hydroxy composition containing one or a plurality of kinds of hydroxy compounds, and then the composition is thermally decomposed, to thereby produce corresponding isocyanate.
