Ethanesulfonic acid, pentafluoro-, potassium salt, also known as potassium pentafluoroethanesulfonate, is a chemical compound with the formula C2F5HKO3S. It is a colorless, crystalline solid that is soluble in water and polar organic solvents. Ethanesulfonic acid, pentafluoro-, potassium salt is derived from ethane-1-sulfonic acid, where all five hydrogen atoms are replaced by fluorine atoms, and the resulting pentafluoroethanesulfonic acid is then neutralized with potassium hydroxide to form the potassium salt. Potassium pentafluoroethanesulfonate is used as a reagent in organic synthesis, particularly in the preparation of fluorinated compounds, and as a catalyst in various chemical reactions. It is also known for its use in the synthesis of pharmaceuticals and agrochemicals, as well as in the production of specialty materials. The compound is considered to be stable, but like many organic compounds, it should be handled with care due to its potential reactivity and the need to avoid exposure.

2837-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2837-92-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,3 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2837-92:
(6*2)+(5*8)+(4*3)+(3*7)+(2*9)+(1*2)=105
105 % 10 = 5
So 2837-92-5 is a valid CAS Registry Number.

Perfluoroalkylsulfone reactions with nucleophiles

Barrera, Michael D.,Cheburkov, Yuri,Lamanna, William M.

, p. 13 - 16 (2002)

Perfluorodialkylsulfones were found to react readily with metal hydroxides in water or alcohol solution and with ammonia to form fluorinated sulfonic acid derivatives.

POTASSIUM PERFLUOROALKANESULFONATES AND PROCESS FOR PRODUCTION THEREOF

-

Page/Page column 17-18, (2008/06/13)

A process for the production of potassium perfluoroalkane- sulfonates which comprises the electrolytic fluorination step of electrofluorinating an alkanesulfonyl halide in anhydrous hydrofluoric acid to obtain a gas containing a perfluoro- alkanesulfonyl fluoride as the main component. The process may further comprise the gas absorption step of reacting the gas with an aqueous solution of potassium hydroxide to form a solution containing a potassium perfluoroalkanesulfonate, the purification step of removing contaminant potassium fluoride, potassium hydroxide and potassium sulfate from the solution, and the concentration/recovery step of subjecting the purified aqueous solution to concentration and drying. In the electrolytic fluorination, the formation of by-products can be inhibited by keeping the proton concentration of the electrolytic solution within the range of 150 to 1500ppm.
