FIELD : chemical industry; methods and devices for reprocessing of the trifluotomethanesulfofluoride into the salt of the triluoromethanesulfo acid.SUBSTANCE : the invention is pertaining to the improved method of production of the, which is the source product for the synthesis the trifluoromethanesulfofluoride derivatives of the triluoromethanesulfo acid, which are used in the thin organic synthesis, in production of the drugs, fungicides, extractants, catalysts, and also to the device for the method realization. The technical result of the invention is intensification of the process, the increase of productivity, the decrease of the losses of the trifluoromethanesulfofluoride at its reprocessing into the salt of the triluoromethanesulfo acid. The solution of the problem provides for feeding of the trifluoromethanesulfofluoride in its gaseous state into the mixture of the hydroxide (or oxide) the alkali-earth or the alkali metal with the water at the constant control of the pH value of the water mixture and the stopping delivery of the trifluoromethanesulfofluoride at рН=7. At that the trifluoromethanesulfofluoride is fed in the descending loop of the circulation of the water mixture at the volumetric ratio of the water mixture to the gas of not less than 6 and under the constant control of the contents of the trifluoromethanesulfofluoride in the effluent gases; feeding of the trifluoromethanesulfofluoride is terminated if its concentration in the effluent gases exceeds 0.5 % of their volume.EFFECT : the invention ensures intensification of the process of reprocessing of the trifluoromethanesulfofluoride into the salt of the triluoromethanesulfo acid, the increased productivity, the decreased losses of the trifluoromethanesulfofluoride at its reprocessing into the salt of the triluoromethanesulfo acid.3 cl, 4 ex, 1 dwg |
