ABSTRACT:
Poly(oxyalkylene) aromatic amides having the formula: ##STR1## or a fuel-soluble salt thereof; wherein a is hydroxy, nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; R.sub.1 and R.sub.2 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R.sub.3 is hydrogen or lower alkyl having 1 to 6 carbon atoms; R.sub.4 is hydrogen or an acyl group of the formula: ##STR2## wherein A.sub.1 is hydroxy, nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; R.sub.5 and R.sub.6 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms and each R.sub.5 and R.sub.6 is independently selected in each --O--CHR.sub.5 --CHR.sub.6 -- unit; R.sub.7 is hydrogen, alkyl having 1 to 100 carbon atoms, phenyl, aralkyl having 7 to 100 carbon atoms, alkaryl having 7 to 100 carbon atoms; R.sub.8 and R.sub.9 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; x is an integer from 2 to 5; y is an integer from 0 to 2; and z is an integer from 5 to 100. The poly(oxyalkylene) aromatic amides of formula I are useful as fuel additives for the prevention and control of engine deposits.
