WebStyrene-divinylbenzene Resin (SDB) Polystyrene- divinylbenzene copolymer (e.g. XAD-2) is a hydrophobic resin that can absorb many water-soluble organic compounds, principally by van der Waals forces and additionally by hydrophobic bonding and dipole–dipole interactions. For binding to the resin the substances must be in a hydrophobic state. Web3 Jul 2024 · A somewhat different plot (of enthalpies of hexane and methanol mixtures) shows the same kind of miscibility gap. Hexane and methanol are completely miscible above about 45 o C, but as the temperature is lowered, mixtures with ratio of 1:1 will separate into two phases. Mixtures with only about 20% of the other solvent are stable at …
