Procedure

A simple lithium 12-hydroxystearate thickened base grease is prepared in a contactor by blending 9.75 parts 12-hydroxy stearic acid (Cenwax A, Union Camp) in 70 parts mineral oil (800 SUS @ 40° C., Texaco HVI) at 77° C. until the acid is dissolved, whereupon 1.75 parts LiOH.H2O (FMC) are added. The contactor is closed and the pressure increases to 80 PSI. The materials are heated to 204° C., the temperature is maintained for 0.2 hour, then the contactor is depressurized. The temperature is reduced to 177° C., the materials are transferred to a finishing kettle, 15.3 parts additional oil are added and the materials are mixed thoroughly until they are uniform. Dropping point is 207° C.
