Abstract:
1. A process comprising: contacting one or more Strecker sulfonation reaction products of one or more halogenated alkyl ethers in the presence of sulfite with one or more polar water soluble organic solvents selected from acetone, methyl ethyl ketone, and C allowing the extraction mixture to separate into an aqueous phase and an organic phase; separating the aqueous phase from the organic phase; contacting the organic phase with a non-polar organic solvent selected from ethyl acetate, cyclohexane, toluene, alkyl ethers, hydrocarbons, and combinations thereof to form a mixed organic phase; and allowing the mixed organic phase time to separate cleanly into another aqueous phase and a final organic phase; wherein the one or more Strecker sulfonation reaction products each comprise at least 30 percent by weight of one or more inorganic salts on a dry basis and one or more surfactant components and the final organic phase following separation comprises less than 20 percent by weight on a dry basis of one or more inorganic salts.
