Pentadecafluorooctanoic acid CAS 335-67-1 PFOA

Perfluorinated compounds (PFCs) were first successfully developed by Minnesota Mining Manufacturing Co., Ltd. (“3M Company”) in 1947. They have excellent thermal stability, chemical stability, high surface activity, and hydrophobic and oleophobic properties. , is widely used in polymer additives, lubricants, fire extinguishing agents, agrochemicals, surfactants, cleaning agents, cosmetics, textiles, blanket manufacturing, upholstery, leather products, surface antifouling agents and the electronics industry, pharmaceuticals, aviation Industry, electroplating and many other industrial production and daily necessities.

Perfluorooctanesulfonate F3 (CF2) 7SO3H (perfluorooctanesulfonate, PFOS) and perfluorooctane acid CF3 (CF2) 6COOH (perfluorooctanoic acid, PFOA) are two typical perfluorinated compounds that are most concerned at present (the abbreviations PFOA and PFOS both represent the acid itself, also represents its salts). The fact that PFOS is ubiquitous in the environment has prompted 3M to announce in 2000 that it will voluntarily phase out the production of PFOS-like substances starting in 2001. In recent years, with the deepening of related research, people have gradually realized the refractory, environmental persistence and bioaccumulation of PFOA, and different concentrations of PFOA have been detected in different environmental media, human and wild animals.
