Abstract

The estimation of the effectiveness of different chlorinating agents for the purification of molten chlorides is performed using the experimental data on oxoacidity (W), hydrolysis constants and Red-Ox ponetnials of Cl₂ and O₂ in chloride melts. The acid-base methods (action of HCl) allow to achieve values of W_lim near 8. A Red-Ox method (direct chlorination) is more effective, W_lim approaches 9.5 and the carbochlorination allows to purify chloride melts to W_lim=19.3.
