Process for preparation of sulphonic acids |
| abstract |
A PROCESS FOR PREPARATION OF MONOSULPHONIC ACIDS AT HIGH SELECTIVITY WHICH COMPRISES REACTING STRAIGHT-CHAIN PARAFFINIC HYDROCARBONS HAVING 10 TO 30 CARBON ATOMS WITH SULPHUR DIOXIDE AND OXYGEN TO PRODUCE THE CORRESPONDING SULPHONIC ACIDS, CHARACTERISED IN THAT THE REACTION IS CARRIED OUT UNDER SUCH CONDITIONS AS TO BRING ABOUT A HOMOGENEOUS REACTION LIQUID PHASE, I.E., THE CONCENTRATION OF SULPHUR DIOXIDE IN THE REACTION LIQUID PHASE BEING 7 TO 23% BY WEIGHT, THE REACTION TEMPERATURE BEING 17 TO 37*C., AND THE CONVERSION OF THE STRAIGHT-CHAIN PARAFFINIC HYDROCARBON BEING 1 TO 7%. |
