Corrosive Action and Oxidation of Vegetable Oils Used in Lubricants

Аннотация

The results of the tests of corrosiveness and oxidative stability of vegetable oils are presented. It is shown that linseed and rapeseed oils have high levels of corrosiveness and oxidative stability. It is established that the basic mechanism of the corrosive action of oils on copper is the reaction with the metal of oil oxidation products with atmospheric oxygen. The anomalously high oxidative stability of linseed oil is related to the predominance of its polymerization processes over hydrolysis processes.
