Abstract:
1. A continuous process for preparing a lithium complex grease, comprising: a. heating a mixture of a C b. passing the mixture of Step (a) through a heat exchanger raising the temperature of the mixture to between about 150° C. to about 200° C.; c. transferring the mixture of Step (b) to a dehydration zone which is maintained at temperature between about 125° C. to about 225° C.; and d. transferring the mixture of Step (c) to a recycle line and adding grease additives, a borated additive for improving the high-temperature properties, and at least one base oil under turbulent mixing conditions to afford a formulated complex grease composition, wherein the continuous process does not include adding a dibasic acid or dibasic ester component and wherein the formulated complex grease composition has a dropping point greater than about 240° C. according to ASTM D2265.
