Michler|ˈmɪxlə(r), ˈmɪk-|
The name of Wilhelm Michler (d. 1889), German chemist, used in the possessive to denote certain compounds first studied by him, as Michler's hydrol, 4,4′-bis(dimethylamino)benzhydrol, [C6H4N(CH3)2]2CHOH, a crystalline compound which is made by the condensation of dimethylaniline and formaldehyde or by reduction of Michler's ketone and is an important intermediate for the synthesis of triphenylmethane dyes; Michler's ketone, the ketone [C6H4N(CH3)2]2CO corresponding to Michler's hydrol, which is made by treating phosgene or carbon tetrachloride with dimethylaniline.
