Michler's ketone Chemical Properties,Uses,Production

Chemical Properties

white to light greenish crystals

Chemical Properties

Michler’s ketone is a is a blue powder or white to green-colored leaflet material.

Uses

In manufacture of dyes and pigments.

Synthesis Reference(s)

Tetrahedron, 38, p. 1163, 1982 DOI: 10.1016/0040-4020(82)85099-0

General Description

White to greenish crystalline leaflets or blue powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

4,4'-Bis(dimethylamino)benzophenone is incompatible with strong oxidizing agents and strong reducing agents .

Hazard

Possible carcinogen.

Fire Hazard

Literature sources indicate that 4,4'-Bis(dimethylamino)benzophenone is combustible.

Safety Profile

Confirmed 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 Exposure

Mutagen. 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.

Carcinogenicity

Michler’s ketone is reasonably anticipated to be a human cagen based on sufficient evidence of carcinogenicity from stud rcinoies in experimental animals.

Shipping

UN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poison Inhalation Hazard. UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN1602 Dyes, liquid, toxic, n.o.s or Dye intermediates, liquid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Dissolve 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.]

Incompatibilities

Incompatible 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 Disposal

Do 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.
