実験手順

Adding 2-methyl tetrahydrofuran prepared by the embodiment 3 and the magnesium-zinc-rare earth oxide composite catalyst into a reactor at the weight ratio of 100:3; opening a heating device to keep temperature of the rector constant at 150° C.; filling excessive CO2 into the reactor, and controlling absolute pressure in the reactor under 2 MPa; performing a cycloaddition reaction between 2-methyl tetrahydrofuran and CO2 in the reactor for 100 minutes to obtain the reaction product, distilling the reaction product to obtain 1,4-pentanediol carbonate, wherein the mole ratio of 2-methyl tetrahydrofuran to CO2 is 1:3, conversion rate of 2-methyl tetrahydrofuran in the cycloaddition reaction is 83%, and yield of the 1,4-pentanediol carbonate is 50%.
