ISOCYANATE PRODUCTION METHOD
An isocyanate production method according to the present invention is a method in which an isocyanate is produced by subjecting a carbamate to thermal decomposition, and includes: a step of preparing a mixture liquid containing the carbamate, an inactive solvent and a polyisocyanate compound; a step of conducting a thermal decomposition reaction of the carbamate by continuously introducing the mixture liquid into a thermal decomposition reactor; a step of collecting a low-boiling decomposition product by continuously extracting the low-boiling decomposition product in a gaseous state from the reactor, the low-boiling decomposition product having a boiling point lower than the polyisocyanate compound; and a step of collecting a high-boiling component by continuously extracting, from the reactor, a liquid phase component which is not collected in a gaseous state at the step of collecting the low-boiling decomposition product.

PROCESS FOR PREPARING HIGH PURITY (METH)ACRYLOYLOXYALKYL ISOCYANATE
A process for preparing a high purity (meth)acryloyloxyalkyl isocyanate having a very small hydrolyzable chlorine content is provided. The high purity (meth)acryloyloxyalkyl isocyanate is prepared by subjecting a hydrolyzable chlorine containing (meth)acryloyloxyalkyl isocyanate to mixing treatment with an epoxy compound and an amine at a temperature of from 110 to 160oC to prepare a mixture; and preparing a high purity (meth)acryloyloxyalkyl isocyanate from the resulting mixture with distillation. In particular, it is possible to effectively prevent (meth)acryloyloxyalkyl isocyanate from polymerization during the distillation by adding a polymerization inhibitor such as phenothiazine and the like.
