The oxidation inhibitivity of an organotin phosphite containing sulfur and that of an organotin borate also containing sulfur were qualitatively investigated by differential thermal analysis (DTA). These compounds suppressed oxidation of squalane considerably. The organotin borate, especially, was an excellent oxidation inhibitor at high temperatures. Moreover, these organotin compounds were characterized by good load-carrying capacities as, indicated by the results of the Timken Test in spite of their low sulfur contents. These new-type additives, organotin phosphite and organotin borate, could be used as multipurpose additives for lubricating oils.
