A fuel additive having formula (I) wherein A1 is a thioether, a sulfoxide, a sulfone, a sulfonic acid, a sulfonamide, a nitrile, a carboxylic acid or ester, or a carboxamide; R1 and R2 are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; R3 and R4 are independently hydrogen or lower alkyl; n is an integer from 0 to 100; and when n is 0 to 10, R5 is polyalkyl having an average molecular weight of 450 to 5,000; and when n is 5 to 100, R5 is hydrogen, alkyl, phenyl, aralkyl, alkaryl or an acyl group having formula: (a) or (II) wherein R6 is alkyl, phenyl, aralkyl or alkaryl; R7 and R8 are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; A2 is a thioether, a sulfoxide, a sulfone, a sulfonic acid, a sulfonamide, a nitrile, a carboxylic acid or ester, or a carboxamide; and x and y are independently integers from 0 to 10; with the proviso that when n and x are both 0, then A1 may not be a carboxylic acid or ester, or a carboxamide.
Additif pour carburants selon la formule (I), dans laquelle A¿1? est un thioéther, un sulfoxyde, un sulfone, un acide sulfonique, un sulfonamide, un nitrile, un acide ou ester carboxylique, ou un carboxamide; R¿1? et R¿2? sont indépendamment hydrogène, hydroxy, alkyle inférieur ou alcoxy inférieur; R¿3? et R¿4? sont indépendamment hydrogène ou alkyle inférieur; n est un nombre entier compris entre 0 et 100; et lorsque n est compris entre 0 et 10, R¿5? est un polyalkyle ayant un poids moléculaire moyen de 450 à 5000; et lorsque n est compris entre 5 et 100 R¿5? représente un groupe acyle ou hydrogène, alkyle, phényle, aralkyle, alkaryle ou selon la formule (a) ou (II), dans laquelle R¿6? représente alkyle, phényle, aralkyle ou alkaryle; R¿7? et R¿8? sont indépendamment hydrogène, hydroxy, alkyle inférieur ou alcoxy inférieur; A¿2? représente thioéther, sulfoxyde, sulfone, acide sulfonique, sulfonamide, nitrile, acide ou ester carboxylique, ou carboxamide; et x et y sont indépendamment des nombres entiers compris entre 0 et 10; sous réserve que lorsque n et x sont tous deux égaux à 0, A¿1? ne puisse pas être un acide ou ester carboxylique ni un carboxamide.
