ABSTRACT
The solubility of caprolactam in methyl tert-butyl ether, isopropyl ether, 1-propanol, 2-propanol, and 1-butanol was measured at the temperature range from 278.15 K to 313.15 K under atmospheric pressure. The experimental data were correlated by the modified Apelblat equation which fits well with the experimental data. The dissolution enthalpy and entropy were predicted. Moreover, the solubility data were correlated using two local composition models: NRTL 1 and UNIQUAC.
