GREASE COMPOSITIONS CONTAINING BORATED ORGANIC COMPOUNDS AS DROPPING POINT ELEVATORS

摘要

A grease composition comprising a major proportion of a grease, a hydroxy-containing soap thickener and a minor amount of a boronated oxazoline compound is disclosed. The hydroxy-containing soap thickener and boronated oxazoline compound are each added in amounts sufficient to increase the dropping point of the grease an appreciable amount. Generally this can be an increase of at least 8 DEG C (15 DEG F) and could be as great as 111 DEG to 139 DEG C (200 DEG F to 250 DEG F) or more. Sulfur and phosphorus compounds can also be incorporated into the compositon.
