Paragraph 0228-0229, (2013/05/09)
A method for producing toluenedicarbamate includes a carbamate production process of producing toluenedicarbamate by reaction between toluenediamine, urea, and/or N-unsubstituted carbamic acid ester, and alcohol; and a benzoyleneurea reduction process of reducing a disubstituted benzoyleneurea and a derivative thereof to 10 mol or less relative to 100 mol of toluenedicarbamate, wherein the disubstituted benzoyleneurea is represented by formula (1) below and has a methyl group and an amino group:
