Synthesis of New Extended Surfactants Containing a Xylitol Polar Group

摘要

A new class of extended surfactants was prepared in which the spacer arm between the polar portion and the hydrophobic alkyl chain was a polymer of propylene gly-col with an average length of six propylene oxide units.The polar head was a single or double xylitol moiety or a xylitol molecule with carboxylic acid functionality.Surfactants containing double xylitol polar head groups showed a much higher critical micelle concentration value than surfactants with a single polar head.
