실험 절차

391 g (3.32 moles) of 1,6-hexanediol, 5976 g (66.4 moles) of dimethyl carbonate and 0.2 g (0.00067 mole) of dibutyltin methoxide were charged in an autoclave. The mixture was heated at 220° C. for 3 hours to advance a reaction. After completion of the reaction, the dimethyl carbonate was removed by evaporation under reduced pressure to obtain a 1,6-hexanediol bismethylcarbonate. The yield of 1,6-hexanediol bismethylcarbonate was 98.0%. A 1,5-pentanediol bismethylcarbonate was also obtained in substantially the same manner as mentioned above except that 1,5-pentane diol was used instead of 1,6-hexane diol.
