Embodiment 1
[0046] Embodiment 1 polyoxyethylene castor oil refining method
[0047] Take 1 part by weight of polyoxyethylene castor oil and add 1.4 parts by weight of acetonitrile to dissolve it, add 1.4 parts by weight of cyclohexane to extract, stir at 150r / min for 15min, put it in a water bath at 30°C, and let it stand for stratification to obtain the acetonitrile solution of the lower layer; Acetonitrile solution, adding 1.4 parts by weight of cyclohexane for extraction, stirring at 150r / min for 15min, standing in a water bath at 60°C for stratification, and obtaining the lower layer of acetonitrile solution; repeating the extraction with cyclohexane for 4 times, and the final acetonitrile extract in In a water bath at 40°C, acetonitrile was removed by rotary evaporation to obtain refined polyoxyethylene castor oil.
Embodiment 2
[0048] Embodiment 2 polyoxyethylene castor oil refining method
[0049] Take 1 part by weight of polyoxyethylene castor oil and add 1.6 parts by weight of acetonitrile to dissolve it, add 1.6 parts by weight of cyclohexane to extract, stir at 150r / min for 15min, put it in a water bath at 55°C, and let it stand for stratification to obtain the acetonitrile solution of the lower layer; Acetonitrile solution, adding 1.6 parts by weight of cyclohexane for extraction, stirring at 150r / min for 15min, standing in a water bath at 55°C for stratification to obtain the lower layer of acetonitrile solution; repeated extraction with cyclohexane for 3 times, and the final acetonitrile extract in In a water bath at 55°C, remove acetonitrile by rotary evaporation to obtain refined polyoxyethylene castor oil.
