酯交换蓖麻油的磷酸酯合成

The Synthesis for Phosphate By Interesterification of Castor Oil

研究了蓖麻油的乙酯化及酯交换蓖麻油的磷酸酯合成，当酯交换度在30％～50％，油／磷＝1:0.75～1：1.25，五氧化二磷／磷酸＝1:0.5～1：1.2（均为mol比），反应时间2.5h～3.5h，温度为70℃，所得酯交换蓖麻油的磷酸酯中的单酯为60％，双酯30％左右，磷酸为6％左右。

The essay discusses castor oil by acetylation and the synthesis for phosphate by interesterification of castor oil. The content of monoglyceride is about 60%,cardiolipin is about 30%,phosphoric acid is about 6% in the product of phosphate by interesterification of castor oil,when extent of interesterification is 30% to 50%,oil to phosphorus is 1:0. 75 to 1. 25,diphosphorous Pentoxide to phosphorop acid is 1: 0. 5 to 1. 2(both are mole ratio),time of reaction is 2. 5% to 3. 5h,temperature at 70℃.
