Michler’s Ketone

 

di-p-dimethylaminobenzophenone; silvery-green crystals. Melting point, 179°C. Virtually insoluble in water, ether, and alcohol but dissolves in pyridine and warm benzene. Michler’s ketone (III) is prepared commercially by treating dimethylaniline (II) with phosgene (I):

Michler’s ketone is a valuable intermediate product in the manufacture of triarylmethane dyes. It was discovered in 1876 by the German chemist W. Michler.

Controls also will be finalized by September 6, 2013, for Michler's ketone, a chemical intermediate used in the synthesis of a variety of dyes and pigments; butanone oxime, an anti-skinning agent used in the formulation of alkyd paints and varnishes; and n-butyl glycidyl ether, which is used as a reactive diluting agent for epoxy resins and a chemical intermediate.
Michler's ketone, butanone oxime, and n-butyl glycidyl ether were the only ones designated as toxic among the 14 substances in Batch 7 of the Challenge to Industry program.
Michler's ketone is the derivative of benzophenone, which has good photoinitiation efficiency and is widely used (28-30).
Michler's ketone itself has good photoinitiation properties because its structure contains parent benzophenone and coinitiator amine.
