実験手順

Adding dimethyl carbonate and furfuryl alcohol in a tubular ester exchange reactor; then adding the metal-rare earth oxide composite catalyst prepared by the embodiment 1, mixing uniformly and performing an ester exchange reaction, then distilling the reaction product to obtain difurfuryl carbonate, wherein the mole ratio of 1,4-pentanediol carbonate to furfuryl alcohol is 1:6, and the weight ratio of the metal-rare earth oxide composite catalyst to the total weight of dimethyl carbonate and furfuryl alcohol is 0.5:100; the ester exchange reaction is performed at a temperature of 160° C. and under an absolute pressure of 3 MPa for 20 minutes; in the ester exchange reaction, the conversion rate of dimethyl carbonate is 95%, and yield of difurfuryl carbonate is 90%.
