ABSTRACT:
A method for manufacturing a lubricating grease having improved properties is described. The method comprises reacting a pyrrolidone with a fatty amine and subsequently adding a metal hydroxide to the reaction when the unreacted fatty amine content ranges between about 33 and about 66 wt. % of the fatty amine originally added. The grease thus formed will be a NLGI #0 grade grease that has the high temperature stay-in-place properties of a NGLI #2 grade grease.
