Michler's ketone Usage And Synthesis
Chemical Propertieswhite to light greenish crystals
Chemical PropertiesMichler’s ketone is a is a blue powder or white to green-colored leaflet material.
UsesIn manufacture of dyes and pigments.
General DescriptionWhite to greenish crystalline leaflets or blue powder.
Air & Water ReactionsInsoluble in water.
Reactivity Profile4,4'-Bis(dimethylamino)benzophenone is incompatible with strong oxidizing agents and strong reducing agents .
HazardPossible carcinogen.
Fire HazardLiterature sources indicate that 4,4'-Bis(dimethylamino)benzophenone is combustible.
Safety ProfileConfirmed human carcinogen with experimental carcinogenic and neoplastigenic data. A poison by ingestion. Mutation data reported. A flammable liquid. When heated to decomposition it emits toxic fumes of NOx.
Potential ExposureMutagen. Animal Carcinogen. Michler’s ketone is a dye intermediate and derivative of dimethylaniline. It is also used in antifreeze formulations, cosmetics, cleaning compounds; heat transfer fluids; as a chemical intermediate in the synthesis of at least 13 dyes and pigments, especially auramine derivatives.
CarcinogenicityMichler’s ketone is reasonably anticipated to be a human cagen based on sufficient evidence of carcinogenicity from stud rcinoies in experimental animals.
ShippingUN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poison Inhalation Hazard.

Purification MethodsDissolve the ketone in dilute HCl, filter and precipitate it by adding ammonia (to remove water-insoluble impurities such as benzophenone). Then crystallise it from EtOH or pet ether. [Suppan J Chem Soc, Faraday Trans1 71 539 1975.] It is also purified by dissolving in *benzene, then washing with water until the aqueous phase is colourless. The *benzene is evaporated off, and the residue is recrystallised three times from *benzene and EtOH [Hoshino & Kogure J Phys Chem 72 417 1988]. [Beilstein 14 IV 255.]
IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from aldehydes, alkaline materials, strong acids, strong bases, strong reducing agents such as hydrideds and active metals. Contact with hydrogen peroxide may form heat- and shock- sensitive explosives.
Waste DisposalDo not discharge into drains or sewers. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed, Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
