The dehydrochlorination of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (DDD), and 1-chloro-2,2-bis(p-chlorophenyl)ethane (DDM) with hydroxide ion was studied in the presence of hexadecyltrimethylammonium hydroxide (CTAOH) micelles at 25.0 deg C.The experimental results clearly deviate from the theoretical behavior expected by the pseudophase-ion-exchange model and can be explained by considering an additional reaction pathway across the micellar boundary.This additional reaction pathway in which hydroxide ion in the aqueous phase reacts directly with the organic substrate in the micelle is probably of a phase-transfer catalysis type.
