A process for the preparation of alkyl sulfate powders, which entails spraying an aqueous solution or dispersion of alkyl sulfates into a head part of a spraying tower through single-component nozzles under pressure sufficient to form a spray mist, and drying the resulting spray mist in co-current manner using an inert gas at a temperature sufficient to afford a powder having a bulk density of at least 300 g/l.

Process for the preparation of alkyl sulfate powder having a high bulk

An alkoxidation production low in alkylene oxide and 1,4-dioxane content is prepared by reacting an alkylphenol or fatty alcohol with an alkylene oxide in the presence of an alkali fatty alkoxide obtained by direct reaction of an alkali hydroxide with a fatty alcohol at elevated temperature.

Method of manufacturing nonionic surfactants low in alkylene oxides and

Alkoxidation products are prepared from amines, fatty acids and oils, which are low in alkylene oxides and 1,4-dioxane by reacting an amine, fatty acid, ester or oil with an alkylene oxide in the presence of a catalyst of an alkali fatty alkoxide obtained by reaction of an alkali hydroxide with a fatty alcohol at elevated temperature.
