Low cost brine tolerant sulfonate and sulfate surfactants having 1,3-dyhydrocharboxy-2-propyl hydrophobic tails
Patent
·
OSTI ID:6228431
Novel sulfonate and sulfate surfactants which have low interfacial tension at high salinity, and their use in enhanced oil recovery are disclosed. These surfactants may be made from relatively inexpensive intermediates, such as monohydric alcohols and epichlorohydrin. These surfactants have 1,3-dihydrocarboxy-2-propyl hydrophobic tails linked by ethoxy linkages to sulfate or alkyl sulfonate moieties.
