実験手順

A lithium hydroxystearate grease thickener was prepared by saponification of a mixture containing 12-hydroxystearic acid (8%) and the glyceride thereof (9%) with lithium hydroxide in a mineral oil vehicle (ISO 150 viscosity grade of a 70/30 mixture of naphthenic and paraffinic stocks) at about 350° F. in a closed contactor. After depressuring and dehydration of the thickener in an open kettle sufficient mineral oil was added to reduce the thickener content to about 9.0%. After cooling to 210° F., a typical grease additive package, consisting of an amine antioxidant, phenolic antioxidant, metallic dithiophosphate, sulfur-containing metal deactivator and nitrogen containing antirust additives, was added. The dropping point of this base grease was 201° C.
