Abstract
Through the shake-flask method, the solubility of p-nitrobenzamide in 12 pure solvents including n-propanol, ethanol, isopropanol, n-butanol, water, isobutanol, ethyl acetate, acetonitrile, dimethyl sulfoxide (DMSO), N,N-dimethylformamide (DMF), N-methyl-2-pyrrolidinone (NMP), and ethylene glycol (EG) was acquired over a temperature range from 283.15 to 328.15 K at ambient pressure p = 101.2 kPa. The mole fractions of p-nitrobenzamide in the equilibrium liquid phase increased as the temperature increased and had the following order in various solvents: DMSO > DMF > NMP > EG > ethyl acetate > ethanol > isopropanol > n-propanol > isobutanol > acetonitrile > n-butanol > water. They were fitted through the Wilson model, modified Apelblat equation, λh equation, and NRTL model. The maximum root-mean-square deviation value and relative average deviation value gained through the four models were, respectively, 56.69 × 10–4 and 6.55 × 10–2. The relative average deviation values achieved were smaller through the mo...
