摘要: Abstract Silica-supported H3PW12O40 (PW), the strongest heteropoly acid in Keggin series, is an efficient, environmentally friendly heterogeneous catalyst for liquid-phase isomerization of styrene oxide into phenylacetaldehyde, industrially important intermediate fine chemical synthesis. The reaction occurs cyclohexane as a solvent under mild conditions at 25–70 °C with low loadings and without PW leaching solution. At 60 °C, yield phenylacetaldehyde reaches 92% 97% conversion, turnover number 19 600. can be recovered reused.
