Sodium salts of sym-secondary alcohol sulfates containing 1123 carbon atoms were prepared from the corresponding purified sym-secondary alcohols which were synthesized by reduction of ketones with aluminium isoproxide. The ketones used in this studies were obtained quantitatively by ketonic decomposition of β-ketoesters.
Some properties of sulfates solution, concerning surface tension, interfacial tension, wetting, foaming, emulsification and detergency, were measured and basic properties as anionic detergent were clarified.
Furthermore, conductivities were measured and compared with strong electrolyte to investigate correlative change in the equivalent conductance vs concentration and then critical micell concentration was determined.
As a result, it was found that sym-secondary alcohol sulfates have excellent properties as anionic detergent and the properties are improved with increase in length of the carbon atom up to C19.
Thus, pentadecane-8-ol sulfate and nonadecane-10-ol sulfate have best properties.
