Fuel additive compositions containing aromatic esters of polyalkylphenoxyalkanols and poly (oxyalkylene) amines

摘要: A fuel additive composition comprising: (a) an aromatic ester compound of the formula: ##STR1## or a soluble salt thereof, wherein R is hydroxy, nitro --(CH 2 ) x --NR 5 6 , and are independently hydrogen lower alkyl having 1 to carbon atoms 0 1; hydrogen, 7 8 atoms; 3 4 polyalkyl group average molecular weight in range about 450 5,000; (b) poly(oxyalkylene) amine at least one basic nitrogen atom sufficient number oxyalkylene units render hydrocarbons boiling gasoline diesel range. The compositions this invention useful as additives for prevention control engine deposits.
