Abstract (en)
[origin: WO0037591A1] 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.
