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.en-USIsomerizationStyrene oxidePhenylacetaldehydeAcid catalysisHeteropoly acidArtigo publicado em periodicoO periódico Applied Catalysis A: General concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
