CONCLUSIONS
The kinetic equations were found for the direct

reaction of the synthesis of zolketal and the reverse
reaction of hydrolysis in the presence of sulfuric acid
as a catalyst. The process was shown to be reversible.
The rates of the direct and reverse transformation were
shown to be described by the first-order kinetic equa-
