Aplicaciones

Hydroquinone is used as a reducing agent and finds applications in black and white photographic developers for film and paper along with 4-(methylamino)phenol sulfate (metol). In this application, silver halides are reduced to elemental silver. It acts as a polymerization inhibitor which prevents polymerization of acrylic acid, methyl methacrylate, cyanoacrylate and other monomers. It undergoes mild oxidation to convert into parabenzoquinone. It is also used as an intermediate to produce antioxidants for rubber and food.

Notas

Air and light sensitive. Incompatible with strong bases and strong oxidizing agents.

Widely used as a radical trap to inhibit polymerization and peroxidation reactions.

Forms inclusion compounds (clathrates) with three molecules of hydroquinone held together by H bonds to form a cage in which a single guest molecule can be accommodated. For a review, see: D. D. MacNicol in Inclusion Compounds, Vol. 2, J. L. Atwood et al, Eds., Academic Press, London (1984), p1.
