Method for obtaining polyunsaturated fatty acid derivatives |
摘要 |
A method of obtaining a polyunsaturated fatty acid derivative comprises contacting a mixture of fatty acid derivatives with a silver salt aqueous solution, and adjusting the free fatty acid content in the silver salt aqueous solution to 0.2 meq or less per gram of silver when repeatedly using the silver salt aqueous solution. A polyunsaturated fatty acid derivative having high purity and excellent quality can thus be economically obtained. |
