PERTHANE (TM) synthesis

4synthesis methods
Ethyl-DDD was commercially produced via a Friedel-Crafts-type condensation reaction. In this process, ethylbenzene (or a suitable ethyl-substituted aromatic) is condensed with dichloroacetaldehyde (or its ethyl acetal equivalent) in the presence of a strong acid catalyst such as concentrated sulphuric acid. This yields the technical-grade product, predominantly the para,para'-isomer along with smaller amounts of ortho,para'-isomer, similar to the synthesis of related organochlorine insecticides like DDD from chlorobenzene and dichloroacetaldehyde derivatives.
