Process for preparing sulphonic acids and sulphonates |
摘要 |
A process for separating sulphonic acids from a paraffin sulphonic acid solution containing in addition to the paraffin sulphonic acids, sulphonic acid, water and optionally non-sulphonated paraffins by mixing the solution with a slightly polar alcohol having solubility in water of less than 7 percent to form an aqueous phase and an organic phase, separating the phases, neutralizing the organic phase and recovering the paraffin sulphonic acids from the neutralized organic phase.
