A process for preparing an ether-capped poly(oxyalkylated) alcohol surfactant is provided. The alcohol has the formula: RO(R1O)xCH(CH3)OR2 wherein R is selected from the group consisting of linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms; R1 may be the same or different, and is independently selected from the group consisting of branched or linear C2 to C7 alkylene in any given molecule; x is a number from 1 to about 30; and R2 is a six membered substituted or unsubstituted, saturated or unsaturated, cyclic or aromatic hydrocarbon radical.
L'invention concerne un procédé de préparation d'agent tensioactif à base d'alcool poly(oxyalkylé) à blocage éther. L'alcool est représenté par la formule: RO(R?1¿O)¿x?CH(CH¿3?)OR?2¿ dans laquelle R est choisi parmi le groupe comprenant un groupe hydrocarboné linéaire ou branché, saturé ou insaturé, substitué ou non substitué, aliphatique ou aromatique, constitués de 1 à 30 atomes de carbone environ, R?1¿ peut être identique ou différent et choisi de manière indépendante parmi le groupe comprenant un alkylène branché ou linéaire en C¿2?-C¿7? dans une molécule quelconque donnée, x représente un nombre allant de 1 à 30 environ, et R?2¿ représente un groupe hydrocarboné à six membres, cyclique ou aromatique, saturé ou insaturé, substitué ou non substitué.
