  • Isomerization of styrene oxide to Phenylacetaldehyde (cas 122-78-1) over supported phosphotungstic heteropoly acid

  • Add time:09/26/2019    Source:sciencedirect.com

    Silica-supported H3PW12O40 (PW), the strongest heteropoly acid in the Keggin series, is an efficient, environmentally friendly heterogeneous catalyst for the liquid-phase isomerization of styrene oxide into Phenylacetaldehyde (cas 122-78-1), an industrially important intermediate for fine chemical synthesis. The reaction occurs in cyclohexane as a solvent under mild conditions at 25–70 °C with low catalyst loadings and without PW leaching in solution. At 60 °C, the yield of phenylacetaldehyde reaches 92% at 97% styrene oxide conversion, with a catalyst turnover number of 19 600. The catalyst can be recovered and reused.

    ▶ The liquid-phase conversion of styrene oxide into phenylacetaldehyde was studied. ▶ Phenylacetaldehyde is an important intermediate in the production of fine chemicals. ▶ H3PW12O40/SiO2 was found to be an active and environmentally friendly catalyst. ▶ A 92% yield was obtained with a catalyst turnover number of 19 600. ▶ The catalyst does not undergo leaching and can be recovered and reused.
