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.]
