Influence of hydroxy groups and peroxides on chlorination must be studied as far as fish oil is used as the raw material for chlorination product. For, their contents in fresh fish oil are usually not large, but increase with autoxidation of oil that advances in storage. The hydroxy groups and peroxides proved to more or less positively retard the chlorination of fish oil. However it seems better to regard the retardation to be caused by various changes in autoxidation of the oil but not as the pure result of the formation of hydroxy groups and peroxides, because the autoxidized oil yielded only a chlorination product little increased in chlorine content, even when it had been strongly reduced in acetyl value by some means before chlorination. It may be certain from the experiment with oleic acid (Table 5) that oxidized oils yield chlorination products unstable to heat. Fish oils, therefore, must be kept out of oxidation, if desired to be ready as the raw material for chlorination product.
