Reaction Steps

After the completion of the feeding, the reaction mixture was aged at that temperature for 3 hours, neutralized with phosphoric acid and analyzed by gas chromatography. It was ascertained that a urethane compound corresponding to isophoronediamine, i.e., 3-methoxycarbonylaminomethyl-3,5,5-trimethyl-1-methoxycarbonylaminocyclohexane (abbreviated to "isophorone dicarbamate" or "IPDC") was obtained in a yield of 99% based on the isophorondiamine and in a yield of 99% based on the consumed dimethyl carbonate.
