| Production method | It is obtained by esterification and reduction of sebacic acid. 1. Esterification Add sebacic acid, ethanol, benzene and p-toluenesulfonic acid to a reaction pot equipped with a water separator, heat and reflux, with water for about 4-5h, until it is separated without water, cool and filter to obtain crude diethyl sebacate. 85% yield. 2. Reduction First, diethyl sebacate and absolute ethanol are put into the reaction pot, and then the metal sodium is gradually added under stirring and cooling, and heated and refluxed until the metal sodium is completely dissolved without residue. Steam distillation is carried out to recover ethanol, then water is added to dilute and cool. The precipitated crude product is recrystallized with benzene to obtain the finished product with a yield of 54%. |
