摘要：
A method for treating an isocyanate residue, which comprises carrying out a thermal decomposition reaction of a carbamate that is produced by the reaction among an amine, urea and/or an N-unsubstituted carbamic acid ester and an alcohol to produce a decomposition solution, separating an isocyanate and the alcohol from the decomposition solution to produce the isocyanate residue, and bringing the isocyanate residue into contact with high-pressure/high-temperature water to decompose the isocyanate residue into an amine; and a method for treating a carbonate, which comprises bringing the carbonate into contact with high-pressure/high-temperature water to decompose the carbonate into an alcohol.
摘要（中）：
一种处理异氰酸酯残基的方法，其包括在胺，脲和/或N-未取代的氨基甲酸酯和醇之间进行由反应产生的氨基甲酸酯的热分解反应以产生分解溶液，分离 异氰酸酯和来自分解溶液的醇，以产生异氰酸酯残基，并使异氰酸酯残基与高压/高温水接触以将异氰酸酯残基分解成胺; 以及碳酸酯的处理方法，其包括使碳酸盐与高压/高温水接触以将碳酸酯分解成醇。
