Reaction Conditions

Reaction Steps

340 g (1 mol) behenic acid and 61 g (0.5 mol) erythritol were added into a 2 L three-neck flask which was equipped with a stirrer, a condenser and an addition funnel. To the flask was added 1 L xylene as a water carrier, followed by addition of a reaction catalyst sulfuric acid (32 g, 8 wt %). The mixture was refluxed at 145±2° C. for 22 hours. When the reaction was ended, the reaction system was allowed to cool to room temperature and stand for 2 hours. The solid was removed by filtration, and the liquid phase was washed with a saturated sodium bicarbonate aqueous solution and petroleum ether in sequence. 260 g solid product was obtained after drying by rotary evaporation. The product was erythritol 2,3-dibehenate as characterized by 1H NMR, and the purity was 91% as characterized by HPLC.
