The present invention is directed to a process for the preparation of polyoxyalkylene ether surfactant compositions comprising the steps of combining an admixture of alkoxylated alcohols with an acid catalyst and 1-6 molar equivalents of an aldehyde. The mixture is reacted at between about 50 °C and about 180 °C and at between about 1 atm and 10 atm pressure in the absence of a distillation step to produce the polyoxyalkylene ether surfactant composition.
L'invention concerne un procédé pour la préparation de compositions tensioactives d'éther de polyoxyalkylène. Ce procédé consiste à combiner un mélange d'alcools alcoxylés avec un catalyseur acide et 1 à 6 équivalents molaires d'un aldéhyde. On fait ensuite réagir le mélange à une température comprise entre 50 et 180 DEG C, et une pression située entre 1 et 10 atm, approximativement, sans étape de distillation, pour obtenir une composition tensioactive d'éther de polyoxyalkylène.
