摘要

Abstract

The solubility and supersolubility of 3

4-bis(3-nitrofurazan-4-yl)furoxan (DNTF) in ethanol+water at different operation were determined by laser monitoring system under atmospheric pressure to study the metastable zone width (MSZW). The modified Apelblat equation was adopted to correlate the experimental solubility data

and the correlation result showed perfect consistent with the experimental data. The standard dissolution enthalpy

standard dissolution entropy and Gibbs energy were calculated according to the experimental solubility data. The effect of the cooling rate

stirring rate

temperature and the concentration of ethanol+water on the MSZW was studied. It was found that the MSZW of DNTF increased with the increasing cooling rate

decreasing temperature

decreasing stirring rate and decreasing ratio of water. And the apparent nucleation order of DNTF in ethanol+water was calculated by the relationship between the cooling rate and the MSZW.
