In this process, organic feedstocks are dispersed in liquid, anhydrous hydrogen fluoride, and an electric current is passed through the solution, causing the hydrogen atoms on the molecule to be replaced with fluorine. The predominant componentsofthe products created by this process have the same carbon skeletal arrangement as the feedstock used, but with allofthe hydrogen atoms replaced by fluorine. However, fragmentation and rearrangement of the carbon skeleton formed. can The also occur and significant degreeoffluorination of amounts ofcleaved, branched and cyclic structures may the organic feedstock is also dependent upon the specific be carbon chain length of the feedstock and parametersof the ECF process such as electrical current and the lengthof time the process is run. It is possible to synthesize fully fluorinated or perfluoroorganic `molecules where all ofthe hydrogen atomsofthe hydrocarbon feedstock have been replaced by fluorine atoms. Using these perfluoroorganic molecules as basic building blocks, unique chemistries can be created by further reactions with functionalized hydrocarbon molecules. (Reaction 1) 3M has produced sulfonyl based fluorochemicals commercially for over 40 years using the ECF process. A basic building blockofsuch products and the highest production volume fluorochemical 3M manufactures is perfluorooctanesulfonyl fluoride (POSF). The starting feedstock for this reaction is 1-octanesulfonyl fluoride. Reaction 1 CsHiSOF + 17 HF 1-Octanesulfonyl fluoride Energy eEeCnF CsFinSO.F + 17H Perfluorooctanesulfonyl fluoride The electrochemical fluorination `mixture of biproducts and waste process yields about 35%-40% straight chain (normal) ofunknown and variable composition comprisedofthe POSF, and following: a ny higher and lower straight-chain homologs, i.., n-CnFanyiSO:F, e.g., CeF13S0,F, C7F1sSOF, CoF19SOzF which comprise about 7%of the process output 2) o`burtapnucthed-chain, perfluoroalkylsulfony! fluorides with various chain lengths, about 18-20% of the 3) astbroauitgh2t0-c-h2a5in%, obfratnhcehoeudt,puatnd cyclic (non-functional) perfluoroalkanes and ethers, which`comprise 4) "tars" (high molecular weight fluorochemical byproducts) and other byproducts, including molecular `hydrogen, which comprise about 10-15%ofthe output.

The commercialized POSF derived products are amixture of approximately 70% linear POSF derivatives and 30% branched POSF derived impurities. CAS Number 24448-09-7 3M Company 3 pDeurrfilnugorpormoedtuhctainoen,,hbayvperobdeuecntvseanntdedwatosttehepraotdmuocstpshearree fionrtmheed.pasTt,hebuvtolpaltainlse awraestbeeipnrgodiumcptls,emseunctheads btoeecnapltaunrdefialnldeddienstarhoyaztahredsoeurselweaasstees blayndtfhilelrmianlthoexipdaastt,iobnutovaerre atlhlecnuerxrtenftelwy ybeeairns.g iTnchienetraartsehdavaet.an filnu-ohroiunsaeteodrweixttherhnyaldrhoagzeanrdaotuosmwsassttilel pirnecisneenrta,tocra.n bTeherebcyypcrloedducbtasc,kminatnoytohfewEhCiFchpraorceesisncoormparleetely partially degraded treatment systems. in stabilization The treatment psrloucdegsesaesssaoncidatdeidscwhiatrhgetdhetoEcCoFntprrololceeds,s in-house, has been wastewater either landfilled or land-incorporated 1998. in the past, but ll of this treatment sludge i being landfilled off-site since early sPyOnSthFesiissoitfsseulbafstcaonmcmeerscuisaeldlyinvmiaabnlye portohdeurct3,Mbuftluiosrporcihmeamriiclaylapnroidmupcotrst.anTthientmearjmoerdiitayteisinustehde to produce functionally derivatized fluorochemicals and high molecular weight polymeric products. mUonlieqcuuelechuesmiinsgtrcioensvcenatniboenaclrehaytderdobcyardbeornivraetaicztiinognsP.
