METHOD FOR PREPARING SURFACTANT COMPOUNDS FROM POLYOLS

摘要

The invention concerns surfactant compositions and a method for preparing same. The method consists in reacting a pentose with an alkadiene in the presence of a palladium catalyst activated by a phosphine, and is characterized in that the reaction is carried out in the presence of a tertiary amine. It can be implemented in aqueous medium or in a polar organic solvent. The compositions obtained in aqueous medium contain for the major part pentose mono(alkadienyl) ethers, while the compositions obtained in organic medium contain for the major part pentose di(alkadienyl) ethers.
