Average molecular weight of fish oil grows gradually with combination, partly addition and partly substitution, of chlorine to some extent and goes down afterwards. It may be pro-bable from the molecular weight change shown in Figs. 2 and 3 that fissions of chlorinated molecules take place in later course of chlorination. From these figures it may be said that the higher molecular weight of the polymerized fish oil, in the earlier course of its chlorination the molecular fissions take place. In earlier course polymerization was observed, which was followed by depolymerization, in the case of oleic acid, but was not in the case of its methyl ester, free palmitic acid and fish oil. Squalene, some kinds of shark oil contain in a large amount as unsaponifiable matter, was examined in respect of the change of molecular weight brought on by chlorination, that might influence the chlorination of fish oil. Squalene undergoes no polymerization but mole-cular fissions on chlorination.
