Abstract

PURPOSE: To prepare the title compound useful as a solvent of resins, and an alkylating agent, etc., rapidly, under mild conditions, in high yield, without producing by-products, by reacting an alkylene carbonate with an aliphatic alcohol in the presence of a complex catalyst composed of a specific acid and a base.
CONSTITUTION: A dialkyl carbonate is prepared by reacting (A) an alkylene carbonate, pref. ethylene carbonate or propylene carbonate, with (B) an aliphatic alcohol, pref. 1W10C alcohol such as methanol, in the presence of (C) pref. 0.5W 20wt%, based on the raw materials, of a complex catalyst composed of (a) a Lewis acid and (b) pref. equi-molar amount, based on the Lewis acid, of a nitrogen- containing organic base such as 1W20C primary, secondary or tertiary aliphatic amine, piperidine, piperazine, etc., at 50W150°C.
