Dicofol (p,p'-dichlorodiphenyl-2,2,2-trichloroethanol) on photolysis undergoes a variety of changes involving addition of solvent radicals, reduction and oxidation.The degradation products have been isolated and characterised.In the solid state also it undergoes photodegradation to p,p'-dichlorobenzophenone (2).In alcoholic solution in the presence of radical quenchers like iodine and paraffin chlorobenzilic esters (6 and 9) are formed in high yields.Irridiation of dil. aqueous solution of 1 by sunlight brings about complete degradation to non-toxic products.Radical mechanism has been proposed for the formation of these products.
