Descripción

General description

Hydroquinone (HQ), a phenolic compound, is also known as 1,4-dihydroxy-benzene. The detection of HQ along with resorcinol and phenol in air samples by synchronous fluorescence method has been proposed. The electrochemical oxidation of HQ has been studied using cyclic and differential pulse voltammetry. Its enthalpies of sublimation, vaporization and fusion have been reported.

Application

Hydroquinone may be used to synthesize bicyclic phosphonate derivative by reacting with phosphonic dichloride.
