ABSTRACT:
A continuous process for manufacture of soap thickened grease compositions where a saponifiable material and a metal base are continuously introduced at an elevated temperature into a saponification zone maintained at superatmospheric pressure and saponified under turbulent conditions, wherein the saponified product is mixed with an aqueous solution of oil-insoluble additive materials at a superatmospheric pressure sufficient for maintaining all water in the liquid phase, wherein the saponified material-additive mixture is heated to an elevated temperature of at least 350.degree. F., wherein the heated saponified material additive mixture is flowed into a dehydration zone maintained at a reduced pressure for flash vaporizing substantially all water therefrom and producing a dehydrated saponified material having oil-insoluble additive evenly dispersed therethrough as particles not exceeding about 10 microns, and wherein the dehydrated saponified material is blended with lubricating oil to produce a grease product.
