실험 절차

20.0 g (0.06 mol) of tetrabutylammonium methanesulfonate are added to a solution of 36.0 g (0.34 mol) of 2-chloroisocyanatoethane and 93.3 g (0.85 mol) of methyl methanesulfonate and the mixture is heated at 120° C for 6 hours. It is distilled in a thin layer evaporator at 180° C. under a pressure of 0.04 mbar and the crude product is purified by distillation. 18.0 g (0.17 mol) of 2chloroisocyanatoethane and 71.0 g (0.65 mol) of methyl methanesulfonate are recovered in this way.
