Perfluorononanoic

A high yield ot the resulting perfluorononanoic acid is obtained by the oxidation of (perfluorooctyl)ethylene with a small amount of ruthenium dioxide and an oxidant [41] (equation 33). [Pg.332]

For the oxidation with potassium permanganate in water it is necessary to use a phase-transfer catalyst to obtain high yields.The phase-transfer agents are generally quaternary ictra-alkylammoniiim or phosphonium salts in concentrations of about 0.5-5 mol % relative to the alkene. Using this method several carboxylic acids, such as tetrafluoro-3-iodopropanoic acid, perfluoroheptanoic acid. perfluoroundecanoic acid, perfluorononanoic acid, and pcrfluorooctanedioic acid can be prepared. In a similar way, 3-(perfluoro-1,l-dimethyl-butyl)prop-l-ene can be oxidized. ... [Pg.696]

Two relaxation processes were evidenced for a large number of surfactants by using two relaxation techniques or, in favorable instances, a single one. Examples of conventional surfactants sodium dodecylsulfate (shock tube (ST) or ultrasonic relaxation (USR) and p-jump - ) sodium tet-radecyl- and hexadecylsulfates (ST and p-jump ) alkylpy-ridinium sulfates (ST and p-jump ) alkylpyridinium halides (ST and p-jump ) alkylammonium halides (ST and p-jump ) surfactants with divalent counterions (T-jump, p-jump, SF ) two-chain surfactants (USR, SF, and p-jump ) nonionic surfactants (T-jump ). Examples of perfluoronated surfactants perfluorononanoate with various counterions (p-jump, T-jump, and SF ). Examples of dimeric surfactants the alkanediyl-a,co-bis(dodecyldimethylammonium bromide) (p-jump and ST °). [Pg.94]

PFOA, Fig. 7.1) has been the most commonly used, but chain lengths of C9 (perfluorononanoic acid— PFNA), CIO (perfluorodecanoic acid—PFDA), and longer have also been utihzed. Although PFCAs can be produced in separate chain lengths, most commercial products consist of mixtures of several chain lengths. [Pg.179]

Downer et al. [29,30] used neutron reflection and surface tension measurements to investigate the adsorption of four fluorinated surfactants at the air-water interface. The surfactants used were two single-chain carboxylates, sodium per-fluorononanoate (NaPFN) and sodium 9H-perfluorononanoate, and two doublechain sulfosuccinates, sodium bis(l/ir, lH-perfluoropentyl)-2-sulfosuccinate (DCF4) and sodium bis(lH, IH, 5H, 5/f-octafluoropentyl)-2-sulfosuccinate (DHCF4). The replacement of a terminal fluorine by hydrogen creates a permanent dipole in the hydrophobic chain and consequently, increases the cmc and the limiting surface tension as well. [Pg.109]
