Process for the purification of the hydrochloric acid by-product of the synthesis of methanesulphonic acid |
| abstract |
The invention relates to the purification of the hydrochloric acid by-product of the synthesis of methanesulponic acid. The methanesulphonyl chloride entrained by the gaseous HC1 by-product is removed using an amount of water ranging from 0.01 to 20%, relative to the mass of HC1 to be treated. The water is injected into the HC1 gas flow and the temperature is lowered to 15 DEG C or below. |
