2011
The present invention relates to a catalyst without the use of formula (1) a non-fluorine-containing aromatic diamine compound represented by the carbonic acid diester compound represented by the formula (2) is produced by reacting the formula (3) carbamate a method for producing compounds, and a method for producing isocyanate compounds without using a catalyst represented by the carbamate compound manufactured from formula (20). R represents a monovalent fluorine-containing aliphatic hydrocarbon group, A represents a divalent aliphatic hydrocarbon group, a divalent alicyclic hydrocarbon group or a divalent aromatic aliphatic hydrocarbon group. H2N-A-NH2 ... (2) O = C = NAN = C = O (20)
