Hildebrandt solubility parameter

Hildebrandt and Scott [1] introduced a solubility parameter that can be used to better predict solubility in nonelectrolytes  [Pg.87]

The Hildebrandt solnbility parameter can be calculated from a considered EOS of polymer as given in Chapter 2 as follows  [Pg.88]

The Hildebrandt solubility parameter can be calculated from the EOS parameters of isothermal compressibility, k, and volume expansivity, p. Kumar [2] gave a similar expression from an analysis using internal energy change, AC/. He defines another solubility parameter, 8 , for internal pressure. The rate of change of internal energy change with volume is the internal pressure of the fluid. [Pg.88]

The EOS developed by Sanchez and Lacombe using the lattice fluid theory can be used to obtain estimates of Hildebrandt solubility parameter, 8 . Equation (2.61) for isothermal compressibility, p, and volume expansivity, k, from the lattice fluid EOS for polymers is used to obtain an expression for 8 as [Pg.88]

The solubility parameter of the polymer is a function of its molecular weight. Molecular weight effects are taken into acconnt throngh the molar volume, v. [Pg.89]


However, Vermue et al. found that pressure-induced changes in Hildebrandt solubility parameter had only a marginal effect on Mucor miehei lipase-catalyzed transesterification rates in SCCO2 [44]. Yoon et al. noted similar nonsensitivity to pressure in their transesterification study of Mucor miehei lipase in SCCO2 [41]. [Pg.433]

Hansen [3] separated the total Hildebrandt solubility parameter, 8 , into three components (1) dispersive, (2) polar, dp, and (3) hydrogen bonding, 8. Thus,... [Pg.89]

The Hildebrandt solubility parameter can be related to the Flory-Huggins interaction parameter by use of regular solution theory. The Hildebrandt solubility parameter can be calculated from one of the EOS theories discussed in Chapter 2 for polymeric systems. It was shown that... [Pg.99]
