| Abstract: | The crude oleamide was purified by molecular distillation, and the optimal technological conditions were found as follows: in the first distillation, pressure is 25 Pa, temperature is 130℃, scraper speed is 340 r/min and flow is 100 g/h; and in the second distillation, pressure is 3 Pa, temperature is 135℃, scraper speed is 340 r/min and flow is 100 g/h. The product was analyzed by GC-MS and the results showed that its mass percentage of oleamide is 96. 44% and the yield is 90. 42%. |
