Abstract:
The present invention describes the method of making anionic ether sulfate surfactants by alkoxylation of a GA using PO and/or EO followed by a sulfation reaction. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of a linear alcohol. The ether sulfate surfactants of the present invention find uses in EOR applications where it is used for solubilization and mobilization of oil and for environmental cleanup.
