カルバメート化合物の製造方法、カルバメート化合物、およびこれを用いたイソシアネート化合物の製造方法
Document Type and Number:
Japanese Patent JP5682622
Kind Code:
B2
Abstract:
The present invention relates to a method of producing a carbamate compound, comprising reacting a fluorine-containing carbonic diester compound represented by formula (1) and a non-aromatic diamine compound represented by formula (2) without using a catalyst, to thereby produce a carbamate compound represented by formula (3), and a method of producing an isocyanate compound represented by formula (20) from the carbamate compound without using a catalyst, wherein R represents a fluorine-containing monovalent aliphatic hydrocarbon group, and A represents a divalent aliphatic hydrocarbon group, a divalent alicyclic hydrocarbon group or a divalent aromatic-aliphatic hydrocarbon group.
