CLEAR LIGHT YELLOW LIQUID | [Uses]
α,α-Dichlorodiphenylmethane is a degradation product of of polychloroaromatic insecticides such as Dicofol (D436700) and DDT. It is also used as a catalyst for photodegradation of plastics. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals. | [Uses]
α,α-Dichlorodiphenylmethane is a degradation product of of polychloroaromatic insecticides such as Dicofol (D436700) and DDT. α,α-Dichlorodiphenylmethane is also used as a catalyst for photodegradation of plastics. | [Preparation]
Dichlorodiphenylmethane is synthesized by the condensation of benzene with carbon tetrachloride (Friedel-Crafts reaction). Add aluminum trichloride and 2/3 amount of anhydrous carbon tetrachloride into the reaction tank, cool to 10-15°C, add 1/12 amount of benzene for reaction, continue to cool to 5-10°C, add the remaining mixture of carbon tetrachloride and benzene dropwise, add after, react at 10°C for 3h. | [Synthesis Reference(s)]
