Accordingly, it is considered that the present invention embraces the use Reissued July 4, 1961 of this material as an extreme pressure agent, not only in turbine oils, but in lubricating oils in general.
• the ability of tris-(Z-chloropropyl)-thionophosphate as an extreme pressure additive and particularly its unique ability as an extreme pressure additive for use in turbine oils in comparison with a number of compounds heretofore recognized in the art as extreme pressure additives is illustrated by the data presented in Table I.
