Hydroxyhydroquinone (1,2,4- trihydroxybenzene ) is a derivative of benzene, a trivalent phenol having three hydroxy groups. The other two isomers of pyrogallol ( 1,2,3- trihydroxybenzene ) and phloroglucinol (1,3,5- trihydroxybenzene ).

Extraction / representation

Hydroxyhydroquinone is accessible by heating p -benzoquinone with acetic anhydride. There is a 1,4-addition, and then, the remaining OH group reacts with further acetic anhydride to Triacetylverbindung. The desired end product is produced by hydrolysis.

Properties

The melting point of Hydroxyhydrochinons is 140 ° C, it is a strong reducing agent.
