MANUFACTURING METHOD OF FLUORINATED CARBAMATES AND ISOCYANATES

摘要

PROBLEM TO BE SOLVED: To provide fluorinated carbamates of high purity more efficiently in a high yield. SOLUTION: The manufacturing method of fluorinated carbamates comprises causing an amine or a polyamine to react with a fluorinated carbonate in the presence of a catalyst containing no metals and containing at least one tertiary amine group. The method may further comprise an additional step for converting the carbamates into corresponding isocyanates. COPYRIGHT: (C)2009,JPO&INPIT
