Solubility, solvency, and solubility parameters

Abstract

473 Okamoto, G.; Mororumi, T. J . Electrochem. SOC. Jpn. 1953b, 21, 573. Okamoto, G.; Morozumi, T.; Sato, N.; Hachiya, M.; Nagayama, M. J . Electro-Okamoto, G.; Okura, T.; Sudo, N.Three-component solubility parameter envelopes have been useful in predicting the solubility/nonsolubility of polymers. The use of threecomponent solubility parameters in predicting both degree of solvency (as measured by inherent viscosity) and solubility/nonsolubility is demonstrated. Predictability is significantly worse if the total solubility parameter is substituted for the three-component parameters. Predictability is significantly improved if the effect of solvent molar volume on solubility is included. These conclusions are based on data for the solubility of three methacrylate polymers in 34 potential solvents, Inherent viscosity data for each of the polymers (for those solvents in which they are soluble) are also given. Three equations (two of which are based on available theory) are used to correlate inherent viscosity with solubility parameter.

Manipulating of polyacrylonitrile membrane porosity via SiO2 and TiO2 nanoparticles: Thermodynamic and experimental point of view

“…The center of this sphere shows the solubility parameter of the polymer. If the amount of solubility parameter of a solvent is located inside the sphere, it means that the solvent is probably able to dissolve the polymer and it is a good solvent otherwise it is a poor solvent 46,47 . The solubility map is showed in two‐dimensional or three‐dimensional coordinates of solubility parameters 25 .…”

Constrained nonlinear optimization for solubility parameters of poly(lactic acid) and poly(glycolic acid)—validation and comparison

“…doi: 10 [5,6]; Van Dyk et al [9]; Tanaka [10]; Panayiotou [11]; Segarceanu and Leca [12]). However, the limitation of this approach is that it will not predict the extent of polymer solubility.…”

A three‐dimensional solubility parameter approach to nonaqueous enzymology

“…Therefore, contrary to the assertion of Laane and cow o r k e r~, '~~'~ it is reasonable to expect that more universal and thermodynamically-interpretable correlations of nonaqueous enzyme activity can be made based on the three-dimensional solubility space as proposed by Despite its theoretical limitations,21'22 Hansen's approach has proven reliable both in qualitatively predicting polymer solubility in organic solvents and solvent blends,I8 as well as in quantitatively correlating the intrinsic viscosity of polymer solutions. 23 Furthermore, reliable experimental values are available for a wide range of solvent^^^'^^ and methods exist for measuring or estimating solubility parameters for solvents having no experimental values.18.20,24,26-28…”
