标题:Thermoanalytical And Preparative Investigations Of The Decomposition Of Potassium Perfluoroorganyl(Fluoro)Borate Salts,K[rfbf3] (Rf=perfluoroalkyl,-Alkenyl,-Alkynyl,And-Aryl Groups) And K[(Rf)2Bf2] (Rf=c6F5 And C6F13)
摘要:Potassium Perfluoroalkenyl(Fluoro)Borates,K[rfbf3],(R-F = Cf2=c(Cf3),Cis-Cf3Cf=cf,And Cis-C6F13Cf=cf) Decomposed At 208-225 Degrees C (T-Max,Dtg). The K[rfbf3] Salts (R-F = C3F7,C6F13,Trans-Cf3Cf=cf,And Trans-C4F9Cf=cf) Decomposed At 273-312 Degrees C (T-Max,Dtg). Both Groups Of Salts Formed Volatile Polyfluoroorganics And K[bf4] As Solid Residue. The Preparative Thermolysis Of Selected Prototypical Salts K[rfbf3] Showed That The Polyfluoroorganics Consisted Of A Mixture Of Internal Perfluorohexenes,C6F12,And 1-H-Tridecafluorohexane,C6F13H,In Case Of K[c6F13Bf3],And Of Perfluorooctynes,C8F14,And Cis-C6F13Cf=cfh In Case Of K[cis-C6F13Cf=cfbf3]. The Salts K[(C6F5)(2)Bf2] And K[rfbf3] (R-F = Cf3C C,Cf3Cf=cfc C,C6F5C C,C6F5,2,3,5,6-C5Nf4) Decomposed In The Temperature Range 249-337 Degrees C (T-Max,Dtg) And Mainly Resulted In Non-Volatile Polyfluoroorganics Besides K[bf4]. The Reaction Path Of The Thermolysis Of Perfluoroalkyl-,Perfluoroalkenyl-,And Perfluorophenyl-(Fluoro)Borates Is Discussed And Compared With That Of Perfluorocarboxylates.
