Abstract
The present invention relates to processes for producing fluorine-containing compounds by means of precipitation reactions from solutions containing fluoride ions wherein the pH value is determined using an electrochemical measuring chain and to electrochemical measuring chains for determining pH values.
Claims20
A process for producing a fluorine-containing compound by a precipitation reaction, wherein the fluorine-containing compound is precipitated from a reaction medium and wherein during the course of the precipitation reaction the pH value of the reaction medium is determined using an electrochemical measuring chain.
An electrochemical measuring chain containing a hydrogen gas diffusion electrode 7 as an indicator electrode and at least one reference electrode, wherein the electrodes form a constructional unit with a housing 1 having an outlet 14 and wherein the housing 1 comprises a reference electrolyte 11 in contact with the reference electrode and a sealed-off gas space 19 above the reference electrolyte 11.
