| titleOfInvention | DIFLUOROMETHANESULFONIC ACID AND A PREPARATION PROCESS |
| abstract | THE INVENTION RELATES TO DIFLUOROMETHANESULPHONIC ACID OF FORMULA CHFSOH. IT ALSO CONCERNS THE PREPARATION OF THE LATEST ACCORDING TO WHICH, IN A FIRST STEP, 100 SULFURIC ACID IS MIXED IN AT LEAST STOECHIOMETRIC QUANTITY WITH SOLID SODIUM DIFLUOROMETHANESULFONATE CONTAINING ABOUT 0.5 MOLE OF APPROXIMATELY BY MOLE, AND THE MIXTURE OBTAINED IS SUBJECTED TO A VACUUM DISTILLATION SO AS TO OBTAIN THE HYDRATED DIFLUOROMETHANESULPHONIC ACID AND IN THAT, IN A SECOND STEP, THE DIFLUOROMETHANESULFONIC ACID RESULTING FROM THE FIRST STEP IS MIXED WITH A QUANTIRE STEP CONTAINING FROM 10 TO 40 BY WEIGHT APPROXIMATELY SO, SUCH AS THE AMOUNT OF SO APPLIED STOECHIOMETRICALLY CORRESPONDS TO THE AMOUNT OF WATER PRESENT IN THE HYDRATIC ACID AND THE RESULTING MIXTURE IS SUBJECTED TO VACUUM DISTILLATION TO OBTAIN THE ACID ANHYDROUS DIFLUOROMETHANESULPHONIC. |
