Title:
UTILIZATION OF VINYL ADDITION COPOLYMER FOR IMPROVING QUALITY OF LUBRICANT ADDITIVE
Document Type and Number:
Japanese Patent JPS61162594
Kind Code:
A
Abstract:
@ Processes for the manufacture of substantially haze free lubricating oil additives such as the zinc salts of dihydrocarbyldithiophosphoric acid and calcium phenate comprising the addition of an effective amount of an acrylamide polymer as a water-in-oil emulsion after the neutralization of an oil solution of the oil soluble moiety of said additive such as the neutralization of a dihydrocarbyldithiophosphoric acid by zinc oxide whereby the resulting colloidal by-products, untreated raw materials and suspended impurities are more susceptible to subsequent separation processes, such as centrifugation and filtration.
