Date Mar. 23, 1995A base fluid for hydraulic or metal working fluids comprises the esterification product having a hydroxyl number below 15 and an acid number below 10 of polymerized fatty acids and a monohydric alkoxylated alcohol, selected from (a) straight or branched chain saturated monohydric C1-C24 alcohols, alkoxylated with 2-25 moles of C2-C5 alkylene oxide and (b) alkoxy poly(alkylene) glycol etherified with C1-C4 aliphatic monohydric alcohol and which is alkoxylated with 2-25 moles of C2-C5 alkylene oxide, optionally the alcohol component also comprises (c) a straight or branched chain C1-C24 aliphatic monohydric alcohol. The acid number of the crude ester is preferably reduced by reacting it with a glycidyl ester of a C5-C22 aliphatic monocarboxylic acid, preferably a C6-C12 branched chain, aliphatic monocarboxylic acid. |
