The solubility of sulfur S-8 in toluene, ethylbenzene, styrene, chlorobenzene, 1,2,3,4-tetrahydronaphthalene, HAS, benzene, cyclohexene, cyclohexane, and hexane was measured by using a gravimetric method in the temperature range between 298.15 and 363.15 K under atmospheric pressure. The solubility data of sulfur S-8 in these solvents were correlated by using the van't Hoff equation, modified Apelblat equation, and lambda h equation. Furthermore, the dissolution of S-8 in each tested solvent is endothermic and nonspontaneous.
