Procedure

Adding 1,4-pentanediol carbonate and furfuryl alcohol in a tubular ester exchange reactor; then adding the prepared metal-rare earth oxide composite catalyst, mixing uniformly and performing an ester exchange reaction, 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 1,4-pentanediol 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 1,4-pentanediol carbonate is 100%, and yield of difurfuryl carbonate is 92%.
