Put 1 mol sorbitol into the reactor, vacuum heat up dehydration, after dehydration, press 3 mol of molten stearic acid and 1kg of sodium hydroxide catalyst. Under the condition of decompression, the temperature rises slowly, rises to 180℃ within 2 h, then rises to 10℃ every 1 h, rises to 210℃ after 3 h, and keeps warm at 210℃ for 5 h, then raise it to 220℃, react for 1 h, sample and measure the acid value. When the acid value reaches 13~15, it is qualified, and stop the ester. Stand still, cool overnight, remove the lower coking material, decolorize the upper layer with appropriate amount of hydrogen peroxide, finally heat up to 100℃, Hot Press molding, cooling packaging is finished product.
