摘要： A product for producing and recovering sulfonated internal olefins wherein an internal olefin is sulfonated to produce a reaction mixture containing intermediate sulfonated compounds, the reaction mixture is neutralized and hydrolyzed to form a product mixture containing hydroxyalkane sulfonates, alkene sulfonates, and hydrocarbon oil, and the product mixture is subjected to azeotropic distillation to effect separation of the hydrocarbon oil from the product mixture.

摘要： A process for producing alkali metal isethionate ethoxylates by reacting an alkali metal isethionate and a polyol, the mole ratio of polyol to alkali metal isethionate being greater than about 7:1, the reaction mixture produced being neutralized with a non-oxidizing inorganic acid to produce a neutralized reaction mixture from which the alkali metal isethionate ethoxylate is recovered.

摘要： A process for preparing an alkoxylation catalyst suitable for alkoxylating compounds such as active hydrogen-containing compounds wherein an alkoxylated alcohol mixture, a calcium-containing compound that is at least partially dispersible in the alkoxylated alcohol mixture, and a carboxylic acid are mixed together to produce a calcium-containing composition having titratable alkalinity, the composition being obtained under conditions to prevent loss of water, the composition being at least partially neutralized with an inorganic acid under conditions to prevent loss of water to produce a partially neutralized calcium-containing catalyst.
