    • An improved process for the solvent extraction of free oil from C.sub.8 to C.sub.24 olefin sulfonation products, which comprises steps for contacting an olefin sulfonation product containing free oil with an alkane-based extraction solvent and phase separating the resulting mixture into an extract phase enriched in free oil and a raffinate phase enriched in sulfonated matter. The invention is particularly directed to the use in such a process of an extraction solvent which comprises one or more C.sub.4 to C.sub.9 alkanes and between about 5 and 35 percent by weight of dimethyl ketone. Deoiled sulfonation products are known for utility as components of detergent formulations for industrial, household and personal care uses.

    • PURPOSE: To purify and obtain industrially and advantageously the titled compound useful as medicines in high purity, by treating a solution containing a specific aminosulfonic acid compound with both ion exchangers having respectively sulfonic acid groups and quaternary ammonium groups.
      CONSTITUTION: A solution containing an aminosulfonic acid of the formula (R
      1 and R
      2 are H or methyl; X is O or S or C-S bond through no X; n is an integer 1W3) is treated with both of (A) an ion exchanger having sulfonic acid groups and (B) an ion exchanger having quaternary ammonium groups to purify the aminosulfonic acid compound. "Diaion SK" series (tradename; manufactured by Mitsubishi Chemical Industries Ltd.), etc. is preferred for the ion exchanger (A), and "Diaion SA" series (manufactured by the same company) is preferred for the ion exchanger (B). The use of the above-mentioned method in the final step of the purification process at the removal of impurities to some extent permits the treatment of the compound of the formula in large quantities by using a small amount of the resin.
