Quinhydrone Usage And Synthesis
Chemical Propertiesa dark green crystalline powder which is a complex formed by benzoquinone and hydroquinone.
Quinhydrone is a general reagent used in potentiometric titrations. It can also be used as a π-acceptor in the formation of charge-transfer complex of analytes for spectrophotometric analysis.
UsesIn pH determinations (quinhydrone electrode).
UsesQuinhydrone is a hydrogen bonded 1:1 charge transfer complex of hydroquinone and p-benzo-quinone having semiconducting properties.
Quinhydrone is addition compound of one mol hydroquinone and one mol Benzoquinone.
Quinhydrone electrode is a type of redox electrode which can be used to measure the hydrogen ion concentration (pH) of a solution in a chemical experiment.
Quinhydrone/methanol treatment for the measurement of carrier lifetime in crystalline silicon substrates has been reported. Surface passivation of silicon substrates by quinhydrone/ethanol treatment has been investigated.
HazardToxic by ingestion.
Purification MethodsCrystallise quinhydrone from H2O at 65o , then dry it in vacuo.[Beilstein 7 H 617, 7 IV 2069.]
