Method for preparing dialkyl carbonate by alcoholysis of urea

The invention relates to a method for preparing dialkyl carbonate by alcoholysis of urea, belonging to the field of chemical synthesis. More specifically, the invention relates to preparation of dialkyl carbonate. The method comprises the following step: subjecting urea and alkyl monohydric alcohol to a reflux reaction under stirring for 6 to 30 hours under the condition of normal pressure or reduced pressure at a reaction temperature of 70 to 150 DEG C by using one or more selected from the group consisting of metal magnesium, calcium, aluminum, chromium, manganese, iron, cobalt, nickel, copper or zinc as a main catalyst and one or more compounds containing donor atom nitrogen, phosphorus, oxygen or sulfur as an auxiliary catalyst so as to prepare the dialkyl carbonate. The preparation method provided by the invention has the following advantages: the dialkyl carbonate is prepared with high selectivity and high yield at a low reaction temperature under the condition of normal pressureor reduced pressure; simple operation, high safety and low cost are achieved in the processing process; and good industrial application prospects are obtained.
