Fuel and lube additives from polyether derivatives of polyamine alkenyl succinimides |
摘要 |
The present invention discloses superior fuel and lubricant additives prepared by the acylation of alkyl or alkenyl succinimides with the polyether half-esters of dicarboxylic acids. The polyether half-esters of dicarboxylic acids are grafted onto the polyamine moiety of alkyl or alkenyl succinimides by reacting the succinimide and the half-ester of the dicarboxylic acid under amidation conditions to form an amide group with an amino group of the polyamine. The process is carried out by first reacting a monofunctional polyalkylene ether with a dicarboxylic acid to produce a half-ester of the dicarboxylic acid. This product is then reacted with an alkyl or alkenyl succinimide polyamine ashless dispersant to product a multifunctional hydrocarbon fuel or lubricant additive that exhibits augmented dispersant properties.
