Process for manufacturing disulfonate surfactants

摘要

A process for manufacturing monosulfonated alkylphenol polyalkylene oxide sulfonates is disclosed. The process produces the monosulfonated alkylphenol polyalkylene oxide sulfonates by a combination of sulfonation to produce a sulfate/sulfonate dianion, followed by a displacement of the sulfate to produce a disulfonate. The process produces a commercially viable disulfonate, which has a wide variety of commercial uses.
