| Abstract: | Specific rotation is an important index to the quality of vitamin E,and how to improve processes to get products with higher specific rotation is urgent for manufacturers nowadays.In this paper,the optimum parameters for vitamin E refinement by using silica gel adsorption process,such as dosage of silica gel,adsorption time,desorption conditions,and recycle of silica gel,were investigated based on a series of experiments.The results showed that the specific rotation of vitamin E obtained through the silica gel adsorption process can meet the requirements of FCC. |
