ABSTRACT:
Nitrogen-containing phosphorus-free carboxylic acid derivatives made by reaction of an acylating agent with an alkanol tertiary monoamine are described. Typically the carboxylic acylating agent is an alkyl or alkenyl succinic anhydride containing about 20 to about 500 carbon atoms in the alkyl or alkenyl group. A typical amine is diethyl ethanol amine. These derivatives are useful in incorporating oil-soluble, water-insoluble functional additives, such as metal salts of acid phosphate and thiophosphate hydrocarbyl esters, into water-based functional fluids such as water-based hydraulic fluids.
