Tin stabilizers for aviation lubricants

摘要

An aviation lubricating oil composition comprises a major amount of base stock oil and a minor amount of triaryltin polyphenyl ether wherein the triaryl groups are phenyl or phenoxyphenol. A method is disclosed for preparation of the tin compounds by reacting polyphenyl ether with t-butyllithium followed by quenching with triphenylstannyl halide.
