p-Toluquinone Chemical Properties,Usage,Production

Chemical Properties

yellow to brownish crystalline powder

Uses

Methyl-p-benzoquinone imine is the products were the tetrahedral adducts. Synthesis of 2H-indazole-4,7-dione derivatives from3-phenylsydnone and p-toluquinone. A Michael addition of 2-methylcyclopentane-1,3-dione to various p-toluquinone imides exclusively afforded the sole products in a regiospecific manner.

Uses

Methyl-p-benzoquinone (MBQ) can be used as a coating that forms an interface between the electrode and lithium (Li) electrolyte for the fabrication of redox flow batteries. It can be reduced during positive electrospray ionization mass spectroscopy (ESI MS) and can be potentially used during corona discharge.

Safety Profile

Poison by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Crystallise p-toluoquinone from heptane or EtOH, dry rapidly (vacuum/P2O5) and stored in a vacuum. [Beilstein 7 IV 2088.]
