Abstract
The paper considers a variant of the dynamic method for determining hygroscopic points of soluble solids, which can be used to determine hygroscopic points of highly viscous saturated solutions. In this variant, the water vapor sorption/desorption rate coefficient is neither specified nor used in calculations. The theoretical foundations of the variant are studied, and an example of calculating the hygroscopic point of fructose is given. The distinct feature of the dynamic method for determining hygroscopic points of substances is its simple execution technique as it requires only analytical balances, dishes for weighing samples, and sealed chambers (desiccators), which makes the method easily implementable in any chemical laboratory.
