摘要: Zinc complex greases with different complexing acids having dropping points comparable to lithium greases and tailor-made dropping points can be made by processing at low temperature in open as well as close kettle process. The present invention discloses a process of manufacturing Zinc complex greases—through reaction of fatty acid and complexing acid with zinc oxide in mineral oil to obtain zinc complex greases having high dropping points of 180 to 280° C.
