Perfluorooctanesulfonate ammonium salt

Salts of perfluorooctanoic acid, in particular ammonium perfluorooctanoate (APFO), have been used as surfactants and processing aids in the production of fluoropolymers and fluoro-elastomers. Industrial production of the salts of perfluorooctanoic acid occur through electrochemical fluorination and telomerization. 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 Suppliers,provide 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 product and the products related with China (Mainland) 99% Ammonium perfluorooctanesulfonate;CAS:29081-56-9 29081-56-9 Changchun Artel lmport and Export trade company China (Mainland) perfluorooctanesulfonate.

Surtvirkende (pH senkende) gjødsel. Inneholder 21% nitrogen (ammonium) og 23% svovel (som sulfat). Ammonium salts are ionic compounds with the formula (R)4N + A - , where R is hydrogen, alkyl or aryl groups and A is an anion. When R is alkyl or aryl then they are referred to as quaternary ammonium salts.

PFOS can be synthesized in industrial production or result from the degradation of precursors. PFOS levels that have been detected in wildlife are considered high enough to affect health Ammonium salt 29081-56-9 C 8H 4F 17NO 3S 517.15g/mol Diethanolamine salt 70225-14-8 C 12H 12F 17NO 5S 605.26g/mol Potassium salt 2795-39-3 C 8F 17KO 3S 538.21g/mol Lithium salt 29457-72-5 C 8F 17LiO 3S 506.06g/mol Melting point >400°C (acid) (OECD 2002) Boiling point no data 1 The MAK-Collection of Occupational Health and Safety 2017, BAT Molbase provides you with 23 Ammonium perfluorooctanesulfonate supplier/manufactures information,includeing Ammonium perfluorooctanesulfonate suppliers giving product prices,purity,lead time. For PFOA, the majority of the aquatic ecotoxicity studies have been conducted with the ammonium salt (APFO) of the prefluorooctanoic acid. Under environmentally relevant conditions in aqueous environmental compartments, PFOA will exist as the fully ionized component (COO −). The surface active properties of the potassium salt of PFOS make a direct determination of the octanol-water partition coefficient impossible.
