Polyalkylphenoxyaminoalkanes having formula (I), wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000; R1 and R2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; and A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms. The compounds of formula (I) are useful as fuel additives for the prevention and control of engine deposits.
Polyalkylphénoxyaminoalcanes de la formule (I), dans laquelle R représente un groupe polyalkyle dont le poids moléculaire moyen se situe entre environ 600 et 5000; R1 et R2 représentent indépendamment hydrogène ou alkyle inférieur contenant environ 1 à 6 atomes de carbone; et A représente amino, N-alkylamino contenant 1 à environ 20 atomes de carbone dans le groupe alkyle, N,N-dialkylamino contenant environ 1 à environ 20 atomes de carbone dans chaque groupe alkyle, ou une fraction polyamine contenant environ 2 à environ 12 atomes d'azote aminé et environ 2 à environ 40 atomes de carbone. Les composés de la formule (I) sont utiles comme additifs de carburant pour la prévention et la régulation de dépôts dans les moteurs.
