Polyoxyisopropylenediamine-acid anhydride-n-alkyl-alkylene diamine reaction product and motor fuel composition containing same

Patent ·
OSTI ID:7083887
;

A fuel composition is described for an internal combustion engine comprising: (a) a major portion of normally liquid hydrocarbon fuel and (b) a minor amount, as a deposit inhibitor additive, of a reaction product of the process comprising: (i) reacting a disbasic acid anhydride with a polyoxyisopropylenediamine, thereby forming a maleamic acid; (ii) reacting the maleamic acid with a N-alkyl-alkylene diamine, thereby forming a reaction product and; (iii) recovering the reaction product.
