Looks like it could also be applied to this.

(Mountain_Girl: "Substitute quinhydrone for benzoquinone ?", Chemistry Discourse)
Here's an interesting patent:
Patent DE3207937 (http://l2.espacenet.com/dips/viewer?PN=DE3207937&CY=gb&LG=en&DB=EPD)
A method of production of 4-alkoxyphenols by reacting hydroquinone with an alcohol at a high temperature and in the presence of benzoquinone and perchloric acid.
Here's a translation of the example (Beispiel)
55 g hydroquinone and 11.5 g 70 % perchloric acid are dissolved in 300 ml of ethanol, then 8.6 g p-benzoquinone is added and (the mixture is) heated under agitation (ie. stirring) to reflux. The reaction mixture is held at reflux temperature for 2 hours, thereafter the batch is concentrated (ie. evaporated) and taken up in 200 ml ethyl acetate and 100 ml water. After seperation of the aqueous phase the organic phase is washed with water and dilute NaHCO3 solution. After removing the solvent medium one obtains 56.1 g (81.2 % Theoretical) 4-ethoxyphenol, Kp 115-119°/0.8 kPa.*
*Kp is probably Kochpunkt (boiling point)
kPa looks like kilopascals
