RH 218 Use and Manufacturing
Trifenofos is an organophosphorus pesticides.
Trifenofos was produced commercially through an organophosphorus synthesis that yielded its phosphorothioate ester structure. Industrial manufacture involved reacting 2,4,6 trichlorophenol with phosphorus oxychloride to form a chlorophosphor intermediate, which was then sequentially esterified with ethyl and propyl alcohols under controlled conditions. The process required strict regulation of temperature and pH to ensure high conversion efficiency and minimise unwanted by products.
