Abstract
Process for the preparation of 2 2 bis (p-chlorophenyl) -1,1-trichlorethane characterized by a continuous process for the preparation of this product by condensation of monochlorobenzene with chloral with fluosulfonic acid as a condensing agent comprising continuously introducing chloral monochlorobenzene and fluosulfonic acid in a reaction zone with the molar ratio of mono-camphorzene to chloral loaded at least 7: 1; the molar ratio between the fluosulfonic acid and the chloral acid charged of at least 3: 1 maintaining the reaction mixture at a temperature not higher than 10ºC and continuously extracting from said zone the resulting reaction mixture.
