Michler's ketone Usage And Synthesis
DescriptionMichler's ketone is a blue powder or white togreen-colored leaflet material. Molecular weight = 268.37;Boiling point ≥360℃ (decomposition); Freezing/Meltingpoint= 172-176*C; Flash point = 220-C; Autoignitiontemperature = 480PC. Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 0. Insoluble in water.
Chemical PropertiesMichler’s ketone is a is a blue powder or white to green-colored leaflet material.
Chemical Propertieswhite to light greenish crystals
UsesMK can be used as an additive that acts as a photoinitiator in the preparation of dyes. It can also be used as a precursor material in the synthesis of 4,4′-bis{N,N,dimethyl, N (2-ethoxy carbonyl-1-propenyl) ammonium hexafluoro antimonate}benzophenone (MKEA).
UsesIn manufacture of dyes and pigments.
DefinitionChEBI: 4,4'-Bis(dimethylamino)benzophenone is a member of benzophenones.
Synthesis Reference(s)Tetrahedron, 38, p. 1163, 1982 DOI: 10.1016/0040-4020(82)85099-0
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.
First aidSkin Contacr52: Flood all areas of body thathave contacted the substance with water.Do not wait tofemove contaminated clothing; do it under the water stream.Use soapto help assure removal. Isolate contaminatedclothing when removed to prevent contact by others. EyeContact: Remove any contact Tenses at once. Immediatelyflush eyes well with copious quantities of water or normalsaline for at least 20- 30 min. Seek medical attention.Imhalation: Leave contaminated area immediately; breathefresh air. Proper respiratory protection must be supplied toany rescuers. If coughing, difficult breathing. or any othersymptoms develop, seek medical attention at once, even isymptoms develop many hours after exposure. Ingestion: IFunconscious or convulsing, do not induce vomiting or giveanything by mouth. Assure that victim's airway is open andlay him on his side with his head lower than his body andfransport at once to a medical facility. If conscious and noCconvutsing, give a glass of water to dilute the substance. Imedical advice is not readily available, do not inducevomiting, and rush the victim to the nearest medicalfacility.
CarcinogenicityMichler’s ketone is reasonably anticipated to be a human cagen based on sufficient evidence of carcinogenicity from stud rcinoies in experimental animals.
storageColor Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in a refrigerator or a cool, dry place awayfrom peroxides, aldehydes, strong acids. Where possible,automatically pump liquid from drums or other storage containers to process containers. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.
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.
