Method of manufacture and use of large hydrophobe ether sulfate surfactants in enhanced oil recovery (EOR) applications

摘要

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.
