Pure anhydrous liquid hydrogen fluoride, per se, is non-conductive. The electrolyte is free trom water in more than a small proportion but need not be anhydrous in a strict sense, 10 Excellent results can be obtained with simple single compartment electrolytio cell arrangements. No diaphragm is needed between electrodes. Fluorination can be completed in one step to directly obtain fully fluorinated product 1~ compounds which are relatively insoluble and either evolve with the cell gases or settle to the bottom of the cell from which they can be drained, depending upon their boiling lmints. The process ~ suitable for continuous as well as 20 batch operation. The .cell can be operated at atmospheric pressure. The cell and the cathodes can be made of iron or steel, and the anodes of nickel, and such cells have been satisfactorily operated at 5 to 8volts, D. C., in producing a wide ~ variety of product compounds. The reaction mechanism ls not fully understood but the electrolyzing process apparently transforms the organic starting compounds at or adjacent to the anode and may be regarded as an 30 anodic process. Hydrogen is evolved at the cathode, being derived from the hydrogen fluoride; and will also evolve in the cell by derivation from other hydrogen-containing compounds which may be present, l~uorinc is not evolved, and the a5 reaction mechanism doe~ not involve the formation of molecular (free elemental) fluorine as an intermediate agent. Product compounds are obtainable (both cyclic and non-cyclic) which have the same number of 40 carbon atoms and same carbon skeletal structure as do the starting compounds, but with partial or total fluorine atom replacement of hydrogen atoms and other atom_s and radicals bonded to the carbon skeleton of the molecule. Fluorine 45 addltlon occurs In the case of unsaturated and aromatic types of starting compounds to produce fully saturated product compounds. Non-cyclic compounds (in addition to cyclic compounds) having the same number of carbon atoms are oh- 11001100..00000022 STATE 075246%2 STATE_07524632 2 fe omeormorecan im saane punt so10008 . tFatrluaeaieisoaniu,abllbttisoleeoffffurrbBoooom monnfddccpcryolceclleilepiacacevvsaaastrgtgoaaeeertUanianncnngdgdecfclofuolmou~aproPnioroinduntemneBddaoasdsudad-duiscitytiietooilnlnes.. shuchpcraadmpororGeursooubAefccanaeAiossftbheboeu bptraaeisrneenndtpfaperre.eooncmte CfCAscalM tlrkaarotibril,oUeenntigh~ys.ieisehccluodossmsmesoaopfofopfuprptnrmoooodelddsyIuucggcacpeoertnbnclceoeoorrnomomaapcl,lpelyyoncTuAiulrvienneceddmsassutinnollbtdmsavrivniintdonnansg-~fpcfgpeiyespwrwcraeleeeir.c-r DProonosle:ndButarhraitfnIogrtapmrraoekvoiifndmgenoso&rremaallaSplalybeolAninqudsiidesmRcusm1sormoictaehsae-l SSC.(o-~ at~olomam~marpOptfothutam hhateoten~mc(h~arhhar~oibevnvo(is.immtnnahs~graektkeLmieeSla~oeieglt'oeaeonc~ontutmeaaolerpinr,dodnnduuufuSlnuem muodbotbeoserieirnortaroseraoaefagfdSdmCddbaeiosltnihnoatoa,nnn-. bmyTethsheeeffsoormramtaitoinoonfofuBeorroocclasharysdcsrboimbdopeasons4i5nsedd S~f himm aao tt1hhaentr hethmmeiisvd ttoalfrotcnho.~uTplcoionemgopKofiuncndasdrs4bo2anrderraeodlbiatctaaiilvnsePfroorpmoretdioinnstohfe aporloudfuloc~tcoTmhpeoukmlnddsscb~laina~bellaetiivne '19 BaDlaselieaelhulyiydeBrsuocTgreihnnreatpeedhrypdorlocpaarbobndoctnershp,ueetdcnudmaisuteopoolofnsnentohtshee ECParonno~mporisinrsveeidnnscaceaniasdossetwiwhtieill1lopdpodeesepripeabentnldidenugu1ppooocbnontoiadtihhineiessensxastca.errlteiJBn~yst 15dcDinaayvneedriiadeeshm.iagrTh.ehdeeofgSorboearrsdoccfavrtibahorenrTmmaoalmloenybaedcbrtiuldseyest4ih5ne4dy LFp~ sieepripopeaparrrreaaorotifnesofddedalfdieSrecbrytsoylioeTmreerfadrlaaoicpptcwkrxt-ioio~syodndinupalucaoldtclsstbss,idy,b-iwlwspelhthriaitloiolcctdahhiutocicoobcatnntanacnibonfrbrmeooeeprm mxorecueaenteda~daaidesccln~h.hyt| GehhiaaimhyiceaatlAeydsseoreoeofn sStaooremosaaorrebsnornpodoentre-iovcfeasot.tracekTsh[,uodsf pTroIanothdc_esocrc~maimenormdncefiorracofllmaolmpoluepolrewlamit-pyitlioioeennlpsds,r,boeuydso-uepccrcotaadnn1bub5ceetbmmaaalddieenoogffutthhpes g_p chhlsoerinatuecdroacnardbMornoAmpiinuriiaddetrcoaTnilbde tthheercmoarlel.y FpM mioroozrioc~~sdkemlmusliociiommftflae,im~m tceadadaonsnBfyneyumuwsmmrrubueelbeetiiefrplurnolloeocfucfosposm~ rummopradpoitouuneucnrgntdsidscsaiconfofmrm ropbopum ofmo~uoundraantdmtndsm eo~s.d.uu|uccIpnhh*i4lapecoiAnomeneegrdiIScnan&upChaepomeirrpcaacblhleSliootrchciiededet1sa.avanoirdlheb88riJ,oopmuoiar.dnea4,lsaofa tetInculmo~b4mu0etdcateguesasri~odltnyoucsleurmbetreenrWltaihlkeistsfhlooercmtOrpeoedirrtiaen 35 8B5atCuriaeied164S8) uofowhircho1ncwdasafi4crrSoboca-rohbeonnrdse- fofluanmiin~nnteeaiTisnnoipnpomrruoiosppnopoyfrrcitoioaodns~ussc4utphsoitocoo6an6l0t0ad%~irBnhieaanlrvgieecabbe)oeeTenanmdooebab- sbirovlulamiinvtghegaaKsrimeupOlpebsi0tahcioamibplogeu1nh3d,-C2Fb0c,4ooTWmhipbiocculshniTdinasnnDoiaivgvn:d tained.
