Paragraph 0024; 0025; 0026, (2016/10/20)
The invention discloses a synthetic method of low-color-number triisooctyl citrate. The method comprises the steps that citric acid and isooctyl ester are taken as starting materials, aluminum salt serves as a catalyst, alkane serves as a water-carrying agent, and under the action of the catalyst and the water-carrying agent, esterification reaction is conducted on the citric acid and the isooctyl ester; after the reaction is completed, the water-carrying agent is distilled to be used with isooctyl alcohol in a matched mode, the catalyst is filtered out through depressurizing, and the low-color-number triisooctyl citrate of which the color number is below 30 is obtained by conducting water washing, weak base washing and steam distillation on the product. The synthetic method of the low-color-number triisooctyl citrate is simple in technology and environmentally friendly, and the triisooctyl citrate with the color number smaller than 30 can be well synthesized.
