Abstract

The invention discloses a method and device for separating and extracting high value-added fatty acid methyl ester in animal and vegetable oil through electromagnetic wave vacuum distillation. According to the method, biodiesel with acid value lower than 1, namely, a mixture of various types of fatty acid methyl ester, is obtained by preprocessing the oil with the animal and vegetable oil such as fish oil and methyl alcohol as the raw materials and ionic liquid as the catalyst; the obtained biodiesel is fine divided to extract poor-heat-sensitivity eicosapentaenoic acid methyl ester with purity of 98%, poor-heat-sensitivity docosahexaenoic acid methyl ester with purity of 98% or high value-added products such as methyl stearate, methyl oleate and methyl linoleate which are quite similar in structure by changing the physical properties of all components in the biodiesel through the electromagnetic wave vacuum distillation coupling technology. The blank of the prior art is made up, the operation procedure is convenient, the operation process is provided for separation of the poor-heat-sensitivity fatty acid methyl ester with similar structures and high added values, and the foundation is laid for fine separation of the fatty acid methyl ester.

Description

technical field [0001] The present invention relates to a new technology coupled with electromagnetic wave technology and vacuum rectification to prepare, separate and purify eicosapentaenoic acid methyl ester, docosahexaenoic acid methyl ester or Methods for high value-added products such as methyl palmitate, methyl stearate, methyl oleate and methyl linoleate. Background technique [0002] my country is rich in marine resources, among which the output of freshwater fish ranks among the top in the world. Therefore, a large amount of fish oil is produced in various production activities, and fish oil still contains a large amount of high value-added fatty acids, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are indispensable and important nutrients for the human body, among which eicosapentaenoic acid can effectively help reduce the content of cholesterol and triglycerides, promote human Metabolism of saturated fatty acids in the body, there...
