Highly selective conversion of guaiacol to -butylphenols in supercritical ethanol over a HWO catalyst.

The conversion of guaiacol is examined at 300 °C in supercritical ethanol over a HWO catalyst. Guaiacol is consumed completely, meanwhile, 16.7% aromatic ethers and 80.

Facile Preparation of Haggite by Reducing VO in Guaiacol/Methanol Solution.

Haggite-structured VO(OH) is prepared via a one-step reduction of VO in a mixture of guaiacol and methanol. Guaiacol delays the overreduction of Haggite to VO. The time window for the stable existence of the Haggite phase is enlarged at low temperature.
