<p>A fuel compsn. comprises a major amt. of a normally liq. fuel and a minor amt. of at least one cpd. of general formula (I), where Ar = 5-30 C aromatic gp. with 0-3 opt. substituents selected from amino, hydroxy, alkyl, polyoxyalkyl, nitro, aminoalkyl and/or carboxy; R = hydrocarbyl; R1, R2 and R3 = H or hydrocarbyl; R4 = H, hydrocarbyl, opt. substituent on AR or lower alkoxy; m = 0 or integer 1-6; x = 0-8; Z each OH, lower alkoxy, (OR5)bOR6 or O- ; R6 = divalent hydrocarbyl; R6 = H or hydrocarbyl; b = 1-30; c = 1-3; y = 1-10; m + c does not exceed the number of valences of the corresp. Ar; A each = amide or amide-contg. gp., carboxyl, ester, amidazoline-contg. gp., oxazoline-contg. gp., acyl-amino or, when Z and A are taken together, a gp. of formula (II) provided at least one A is an amide or an amide-contg. gp.</p> |
