A process for base hydrolysis of a fluorinated sulphonyl fluoride by treatment of the fluoride with at least one mole equivalent of water in a basic solvent for a sufficient time to obtain a salt of a corresponding fluorinated sulphonic acid with the basic solvent and separating the obtained salt from the solution, wherein the basic solvent is selected from the group of tertiary amines.

Process for the hydrolysis of fluorinated sulphonyl fluorides

Process for the preparation of a fluorinated sulphonic acid compound by hydrolysis of a corresponding fluorinated sulphonyl fluoride, wherein the hydrolysis is carried out in the presence of a tertiary amine, comprising steps of recovering a mixture of a salt of hydrolysed fluorinated sulphonyl fluoride with the tertiary amine and an ammonium fluoride salt of the tertiary amine;

Process for the synthesis of fluorinated sulphonic acids

Process for the electrochemical fluorination of a hydrocarbon substrate in the presence of a HF-containing electrolyte under electrochemical fluorination conditions to a fluorinated product and a hydrogen gas by-product, the improvement of which comprises additional steps of
