Continuous lithium complex grease manufacturing process with a borated additive

摘要

A continuous process with increased production throughput of a high dropping point lithium complex grease composition comprising the steps of heating a mixture of a C12 to C24 hydroxy fatty acid or a C12 to C24 hydroxy fatty acid ester, an aqueous solution of lithium base and at least one base oil at an elevated temperature; removal of volatiles (i.e., water and methanol, etc.) in a dehydration zone; and transferring the mixture to a recycle line wherein additives, a borated additive and at least one base oil are added to afford a formulated grease composition.
