| production method | is derived from the esterification of the acid with ethanol. The raw materials of 11 enoic acid and ethanol were directly esterified under sulfuric acid catalysis to obtain crude ethyl 11 enoate, which was then neutralized, washed with water and fractionated under reduced pressure to obtain a finished product. Another method of production is the transesterification of glyceryl triricinoleate with ethanol to obtain ethyl ricinoleate, which is then cleaved at 550-600 °c. The lysate was subjected to fractional distillation under reduced pressure, and a fraction of 150-220 ° C. (2.67-8.0kPa) was collected, which was ethyl 11 enoate. the reaction mixture was obtained by heating to 70 ° C. With ethyl alcohol in the presence of hydrochloric acid followed by esterification and distillation. |
