COMPOSITIONS AND METHODS FOR CONTROLLING THE STABILITY OF ETHERSULFATE SURFACTANTS AT ELEVATED TEMPERATURES
摘要
The present invention describes the method of making an ether sulfate surfactant solution hydrolytically stable by adding one or more alkalinity generating agents at levels greater than 0.05%. The surfactant solutions of the present invention have half-lives > 8 months at 100?C and find uses in EOR applications, environmental cleanups, detergent industry, and any other surfactant based high temperature applications.
