General Description

1-(4-Chlorophenyl)-1-phenyl-2,2-dichloroethane, also known as Dicofol, is a chemical compound that is commonly used as a pesticide. It is derived from DDT, a well-known insecticide. Dicofol is a white crystalline solid and is insoluble in water, but soluble in organic solvents. It is primarily used to control mites and insects on a variety of crops, including citrus fruits, cotton, and vegetables. However, Dicofol has been found to have detrimental effects on the environment and human health. It is considered to be a potential endocrine disruptor and has been banned or restricted in several countries. Additionally, it has been identified as a persistent organic pollutant (POP) and is subject to international regulation under the Stockholm Convention. Due to its potential for environmental and human health harm, the use of Dicofol is increasingly being phased out in favor of safer alternatives.

Facile and catalytic degradation method of DDT using Pd/C-Et3N system under ambient pressure and temperature

The catalytic degradation method of p,p′-DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane] and its regioisomer o,p′-DDT [1,1,1-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl)ethane] using the Pd/C-Et3N system under ambient hydrogen pressure and temperature was established. The presence of Et3N was necessary for the quick and complete breakdown of DDT. The independent degradation study of two intermediates, p,p′-DDD [2,2-bis(p-chlorophenyl)-1,1-dichloroethane] and p,p′-DDE [2,2-bis(p-chlorophenyl)-1,1-dichloroethylene] using GC-MS let us to speculate the degradation pathway of p,p′-DDT. In the initial phase of the reaction, p,p′-DDT degradation splits into two ways: a dehydrochlorination pathway and a hydrodechlorination pathway. In each pathway, reaction starts from an aliphatic moiety and subsequent hydrodechlorination from the benzene moieties takes place in a stepwise manner. The former pathway leads to the formation of 1,1-diphenylethane and the latter leads to the formation of 1,1-dichloro-2,2-diphenylethane. These diphenylethane analogs, which are less toxic compared with p,p′-DDT, are terminal degradation products in our system. The distinctive features of our catalytic degradation method of DDTs are reliability, simplicity, efficiency, and inexpensiveness.
