Abstract
The preparation and properties of a homologous series of sodium salts of alkyl pentaerythritol ether sulfates, containing 12, 14, 16 and 18 carbon atoms are presented. The sodium salts of alkyl pentaerythritol ether sulfate, possessing two primary hydroxy groups and a sulfate group as hydrophilic portions, were prepared by sulfation of the corresponding alkyl pentaerythritol ethers obtained by the etherification reaction of pentaerythritol with alkyl bromide.
These surfactants showed excellent properties in aqueous solution such as lower cmc, higher stability toward calcium ions and low Krafft points. They were noted to function as highly effective calcium soap dispersing agents.
