ABSTRACT

The solubilities of sulfur S8 in toluene, ethylbenzene, styrene, chlorobenzene, tetrahydronaphthalene, HAS, benzene, cyclohexene, cyclohexane and hexane were measured by using gravimetric method at the temperature range between 298.15 and 363.15 K under atmospheric pressure. The solubility data of sulfur S8 in these solvents were correlated by using the van t Hoff equation, modified Apelblat equation and eh equation, respectively. Furthermore, the dissolution of S8 in each tested solvent is endothermic and non-spontaneous.
