As an anhydrous aluminium chloride added to the chlorination mixture of polymerized fish oil caused the melting point of a product to raise remarkably, some of the favorable conditions on the use of this reagent were researched After separation of the strong phosphoric acid with which the reaction mixture was treated as previously reported, the mixture was subjected to the action of an anhydrous aluminium chloride amounting to 20% by weight of the polymerized fish oil used at the start. Temperature of treatment was to be raised step by step from 60°C to 90°C, after the bubbling of hydrogen chloride caused by the addition of aluminium chloride added became quiet down. The product was seperated as precipitate by methanol from the reaction mixture at the end of the reaction. A fraction constituting about 40% of the product thus obtained was soluble and the rest insoluble in methanol. This insoluble part was characteristic in its insolubility not only in methanol, ethanol but in most of organic solvents except trichloroethylene and chloroform. But in respect of the stability against heat, any notable difference was scarcely brought about by eliminating the methanol-soluble part from the product. Therefore, it will not be all advantageous to take out only the insoluble part at a concider-able loss in yield.
