METHOD FOR PREPARING HIGH PURITY UNSATURATED FATTY ACIDS METHYL ESTER FROM PALM OIL OR WASTE ANIMAL OIL

摘要

In the present invention, after adding GMS or SPAN-based emulsifier and methanol or ethanol to palm oil or fatty acid methyl ester derived from animal oil and waste resources, cooling and centrifugation to reduce saturated fatty acid methyl ester, and then methanol and 1,2-dichloroethane ( Dichloroethane or Dichloromethane) is a method of preparing a high purity unsaturated fatty acid methyl ester by performing a urea water drop determination method by dropwise adding a high temperature urea aqueous solution to a mixed solution at room temperature. In the case of using the method for producing a high-purity unsaturated fatty acid methyl ester according to the present invention, compared to the prior art unsaturated fatty acid methyl ester separation technology, palm oil or animal fat and oil wastes that are not used in Southeast Asia can be recycled, and the amount of waste water generated and thermal energy It has the advantage of being able to provide smoothly as a raw material necessary for preparing dimeric acid methyl ester due to its low use and short reaction time.
