Synthesis
At 0-5°C, a photoinitiator is added, and dimethyl carbonate and chlorine are subjected to light reaction. The reaction is stopped, and the product is distilled and separated to obtain dimethyl monochlorocarbonate. At 70-100°C, a catalyst is added, and dimethyl monochlorocarbonate and isopropanol are added to a distillation tower capable of controlling the reflux ratio. Methanol is distilled and separated under normal pressure while reacting. After the reaction is completed, excess isopropanol is distilled off under reduced pressure, and finally chloromethyl isopropyl carbonate is distilled under reduced pressure.
