purpose: to evaluate the effect of fullerene on chemical properties of naphazoline drug in   water by density functional theory (dft) methods.   materials and methods: naphazoline belongs to the imidazoline class of sympathomimetics.   the present study on naphazoline drug and its fullerene connected form were carried out using   computerized calculations of gaussian program in b3lyp/6-31g leve...

The solubility of naproxen in binary mixtures of polyethylene glycol 200 (PEG 200) + water at the temperature range from 298.0 K to 318.0 K were reported. The combinations of Jouyban-Acree model + van't Hoff and Jouyban-Acree model + partial solubility parameters were used to predict the solubility of naproxen in PEG 200 + water mixtures at different temperatures. Combination of Jouyban-Acree m...

1. The solubility of d-valine in water has been determined over a range of 0-60 degrees . 2. The solubility of this amino acid varies with the mode of crystallization, indicating a dependence of solubility on the crystal form.

the quantitative structure–property relationship (qspr) method is used to develop the correlation between structures of crude oil hydrocarbons (80 compounds) and their boiling point and water solubility. sub-structural molecular fragments (smf) calculated from structure alone were used to represent molecular structures. a subset of the calculated fragments selected using stepwise regression (fo...
