High-temperature hydrolysis of melts based on alkali metal halides

1 High-temperature hydrolysis of melts based on alkali metal halides 

The acid-base reactions of this kind are studied mainly for individual alkali metal halides and some of their most used mixtures. 

Investigation of the pyrohydrolysis of solid and fused NaCl in the temperature range 600-950 °C was reported by Hanf and Sole [255], who proposed the so-called dynamic method for this purpose. This consists in passing (bubbling) a wet inert gas (nitrogen) through the layer of the solid salt or the melt, which gives rise to the process of pyrohydrolysis  

The HC1 produced from the melt or solid is absorbed by water and its quantity determined by conventional acid-base titration. The treatment of the experimental results is as follows. The expression for the rate of HCl-production may be presented as
