Chlorodiphenylmethane Usage And Synthesis

Chemical Properties

Clear colorless to yellow liquid

Uses

Chlorodiphenylmethane was used as initiator during the controlled radical polymerization of styrene catalyzed by ionic iron complex. It was also used as the starting reagent in the synthesis of trimethylhydroquinone derivatives.

Application

Benzhydryl chloride is used as a pharmaceutical intermediate, such as diphenhydramine intermediate.

Preparation

Chlorodiphenylmethane was synthesized by the radical substitution reaction between diphenylmethane and chlorine gas.

Purification Methods

Diphenylmethyl chloride (benzhydryl chloride) [90-99-3] M 202.7, m 17.0o, b 140o/3mm, 1 6 7o/17mm, n 1.5960. Dry the chloride with Na2SO4 and fractionally distil it under reduced pressure. [Beilstein 5 H 590, 5 I 278, 5 II 500, 5 III 1790, 5 IV 1847.]
