PHOSPHATE ESTER COMPOSITIONS IN A WEIGHT RATIO GREATER THAN 1:1 MONOALKYL TO DIALKYL PHOSPHATE USED AS LUBRICANT ADDITIVES

摘要

Alkyl phosphate esters having a high monoalkyl content are used as lubricating additives in functional and lubricating fluids. The esters have a weight ratio of monoalkyl phosphate esters to dialkyl phosphate esters of greater than one. The alcohols from which the esters are prepared are preferably non-ethoxylated. The functional or lubricating fluids can be oil-based or aqueous based.
