Reaktivität anzeigen
4,4'-Bis(dimethylamino)benzophenone is incompatible with strong oxidizing agents and strong reducing agents .
Hazard
Possible carcinogen.
Brandgefahr
Literature sources indicate that 4,4'-Bis(dimethylamino)benzophenone is combustible.
Sicherheitsprofil
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.
mögliche Exposition
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.

läuterung methode
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.]
Inkompatibilitäten
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.
