Reaction Steps
Into a flask equipped with a reflux cooler, a water separator and a dropping funnel, there were charged 113.5 grams (1.25 moles) of dimethyl carbonate. The substance was heated to 80° C. A solution of 1.4 grams (0.025 moles) of potassium hydroxide in 225.0 grams (2.5 moles) of dimethylethanolamine was then added in drops over a period of 30 minutes. The methanol formed during the reaction was removed by azeotropic distillation using cyclohexane as an entraining agent.
