WebSep 18, 2002 · The oxidation of styrene in CH 3 CN:H 2 O (v/v=1:1) catalyzed by MPs with various oxidants afforded a complex mixture of phenyl-oxirane, phenylacetaldehyde and benzaldehyde. Because the reaction was performed in aqueous medium, pH will have some effect on the activity and selectivity. 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.
