Embodiment 1
[0020] Take 100 grams of natural vitamin E, dissolve it in 300 grams of ethanol, add silica gel, under the protection of nitrogen, control the system temperature at 63 ° C, and use the external circulation method to fully mix for 2 hours. After stopping, filter, the filtrate is concentrated by vacuum distillation, and then purified by molecular distillation to obtain the product. It has been detected that polyaromatic hydrocarbons are 18ppb, of which the light part is 17ppb, the heavy part is 1ppb, and benzopyrene is less than 0.5ppb.
Embodiment 2
[0022] Take 100 grams of natural vitamin E, dissolve in 300 grams of butyl butyrate, add activated carbon, under the protection of nitrogen, control the system temperature at 61 ° C, and fully mix for 2 hours by means of external circulation. After stopping, filter, the filtrate is concentrated by vacuum distillation, and then purified by molecular distillation to obtain the product. It has been detected that polyaromatic hydrocarbons are 12ppb, of which the light part is 11.2ppb, the heavy part is 0.8ppb, and benzopyrene is less than 0.5ppb.
Embodiment 3
[0024] Take 150 grams of natural vitamin E, dissolve it in 500 grams of ethanol, add activated carbon, under the protection of nitrogen, control the temperature of the system at 62 ° C, and use the external circulation method to fully mix for 2 hours. After stopping, filter, the filtrate is concentrated by vacuum distillation, and then purified by molecular distillation to obtain the product. It has been detected that the polyaromatic hydrocarbons are 8ppb, of which the light part is 5ppb, the heavy part is 3ppb, and benzopyrene is less than 0.5ppb.
