Method for purifying alkane sulfonic anhydride and method for producing alkane sulfonic acid using purified alkane sulfonic anhydride |
| abstract |
The invention relates to a method for purifying alkane sulfonic anhydride, which comprises the following steps: (a) feeding a material stream containing alkane sulfonic anhydride, sulfuric acid, high boilers and residual low boilers to molten crystals (25) to form Crystals of the alkane sulfonic anhydride suspended in the mother liquor, (b) solid-liquid separation is performed to remove the crystals from the mother liquor, and (c) the crystals are washed as appropriate to remove the mother liquor adhering to the crystals.n n n The present invention further relates to a method for producing an alkanesulfonic acid using the purified alkanesulfonic anhydride. |
