Title:
A manufacturing method of xylylene diisocyanate, and a manufacture device of xylylene diisocyanate
Document Type and Number:
Japanese Patent JP6022039
Kind Code:
B2
Abstract:
A method for producing xylylene diisocyanate includes a thermal decomposition step of thermally decomposing xylylene dicarbamate; a first separation step of separating, from the thermal decomposition product obtained in the thermal decomposition step, an isocyanate-containing component containing xylylene diisocyanate as a main component and an alcohol-containing component containing alcohol as a main component and containing xylylene diisocyanate as a subcomponent; a second separation step of separating xylylene dicarbamate and alcohol from the alcohol-containing component obtained in the first separation step; and a returning step of returning xylylene dicarbamate obtained in the second separation step to the thermal decomposition step.
