ABSTRACT:
Pure DHA and pure EPA can be obtained from a mixture of EPA and DHA in a solution by forming salts of DHA and EPA which have different solubilities in the solvent, cooling the solution until the salt of EPA is formed, filtering the solution to recover the salt of EPA, and acidifying the EPA salt and the DHA salt to obtain pure EPA and pure DHA.
