  • Method for producing xylylene diisocyanate and system for producing xylylene diisocyanate
    Patent number: 9512067
    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.
