摘要

Abstract

The laser monitor technique was used to determine solubilities and supersolubilities of HNS in

-dimethylformamide

dimethyl sulfoxide

acetonitrile

-methyl-2-pyrrolidone and 1

4-butyrolactone. The experimental solubility values were correlated with λ

equation

modified Apelblat equation and NRTL model. Furthermore

the dissolution enthalpy

dissolution entropy and the Gibbs energy of HNS were calculated by the experimental data. The results show that the solubilities of HNS in the above solvents increase with the increasing temperature. Besides

at the same temperature

the order of solubility is

-methyl-2-pyrrolidone dimethyl sulfoxide

-dimethylformamide 1

4-butyrolactone acetonitrile. The temperature dependence of predicted solubility is in agreement with the experimental data.
