Abstract
The equilibrium solubility of N-(9-fluorenylmethoxycarbonyloxy)succinimide in {dimethyl sulfoxide (DMSO), ethanol, ethylene glycol (EG), N,N-dimethylformamide (DMF)} plus water were determined by means of the isothermal equilibrium method at (283.15–328.15) K under atmosphere pressure. The measured values of N-(9-fluorenylmethoxycarbonyloxy)succinimide are positively increased with the increase of temperature in a certain cosolvent composition; however, that decreased when the content of water was gradually increasing and the largest solubility data was observed in pure DMF (0.04989 in mole fraction, 328.15 K). The mole fraction solubility in monosolvents ranked as DMF (9.693 × 10–3, 298.15 K) > DMSO (6.406 × 10–3, 298.15 K) > ethanol (8.237 × 10–4, 298.15 K) > EG (3.136 × 10–4, 298.15 K) > water (7.378 × 10–6). Under conditions of the same temperature and cosolvent composition, the solubility maximum of N-(9-fluorenylmethoxycarbonyloxy)succinimide was found in (DMF + water, 9.693 × 10–3 in mole fraction ...
