Abstract
1470160 Dimethylcarbonate ANIC SpA 16 Feb 1976 [21 Feb 1975] 06041/76 Heading C2C Dimethyl carbonate is recovered from a mixture with methanol by distillation at elevated pressure. The mixture may be an azeotrope and the fractional distillation may be in the presence of an inert gas and in the range of 2 to 30 atmospheres absolute pressure.
