反応手順
201.5 g of 28% strength aqueous sodium hydroxide and 2.0 g of dimethyllaurylbenzylammonium chloride were added to a solution of 250 g of 1,1-bis(chlorophenyl)-2,2,2-trichloroethane in 100 g of monochlorobenzene at 50° C. The mixture was heated at reflux (90° C.) for 20 hours. The organic phase was separated by phase separation and was washed three times with 100 g of water. After distillation of the monochlorobenzene, 219.3 g of 1,1-bis(chlorophenyl)-2,2-dichloroethylene were obtained (y=97.8%) with 0.10% of 1,1-bis(chlorophenyl)-2,2,2-trichloroethane.
