    摘要: An improved process for the preparation of narrow-range alkanol alkoylates by the addition reaction of higher alkanols with alkylene oxides, particularly ethylene oxide. U.S. Pat. No. 4,721,816 describes a process in which alkylene oxides are added to alkanols by reaction in the presence of a catalyst prepared by contacting a sulfur-containing acid such as sulfuric acid with one or more aluminum compounds selected from the group consisting of aluminum alcoholates and aluminum phenolates. Under the present invention, that process is improved by carrying out the process in the further presence of water, provided that certain critical restrictions are placed upon the proportions of the water and of the sulfuric acid and aluminum catalyst components. The process improvement of the invention offers substantial improvement in alkoxylation reaction rate and/or selectivity of the reaction to the desired alkanol alkoxylate products, rather than to by-products such as polyalkylene glycols. The narrow-range alkanol alkoxylate products of the process of the invention have utility, for instance, as nonionic surfactant components of detergent formulations.

    摘要: Alkylene oxide adducts of higher alkanols are prepared by a process which comprises contacting and reacting an alkylene oxide reactant comprising one or more C.sub.2 to C.sub.4 vicinal alkylene oxides with an alkanol reactant comprising one or more C.sub.6 to C.sub.30 alkanols in the presence of a catalytically effective amount of a catalyst which combines (i) one or more phosphorus-containing acids with (ii) one or more aluminum compounds selected from the group consisting of aluminum alcoholates and aluminum phenolates, the relative molar ratio of component (i) to component (ii) being in the range from about 0.1:1 to 2.5:1. Alkanol alkoxylates, and particularly alkanol ethoxylates, prepared in this manner are characterized by a relatively narrow-range distribution of alkylene oxide adducts and by a relatively low content of residual alkanol. The products of this process are nonionic surfactants, particularly useful as components of detergent formulations.
