Analysis of soil extracts for inorganic and organic tracer anions via high-performance liquid chromatography: Analysis of soil extracts for inorganic and organic tracer anions via high-performance liquid chromatography. Bowman, Robert S. (U. S. Water Conserv. Lab., Agric. Res.Chemicals with cas numbers 302-04-5 and 385-00-2 also play role. Serv., Phoenix, AZ 85040, USA). J. Chromatogr., 285(3), 467-77 (English) 1984. CODEN: JOCRAM. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Section cross-reference(s): 61 A high-performance liq. chromatog. technique allowing simultaneous quantification of Br-, SCN-, I-, and 2,6-difluoro- [385-00-2], pentafluoro- [602-94-8], o-(trifluoromethyl)- [433-97-6], and m-(trifluoromethyl)benzoic acid [454-92-2] in soil exts. required minimal sample pretreatment. The anal. column was packed with the strong anion exchanger Partisil 10 SAX and was preceded by a guard column packed with pellicular anion exchanger. The mobile phase was 0.005M KH2PO4 buffer adjusted to pH 4.0 with H3PO4, with 10% MeCN as org. modifier. A UV absorption detector was used at a detection wavelength of 205 nm. The method allowed accurate measurements of tracer concns. in the presence of high background levels of Cl-, NO3-, and naturally-occurring org. solutes, although high NO2- levels can cause interference. Recoveries from soil ext. spiked with 25 ng anion ranged 91-138%, with generally greater accuracy for the early eluting fluororg. species. The corresponding std. deviations ranged ±0.0 to ±1.1. The technique proved reliable for analyzing exts. from a variety of sources having wide variations in concns. of the tracers, which are of interest for studying water movement in soils. .

Measurement and correlation of solubilities for trifluoromethylbenzoic acid isomers in supercritical carbon dioxide: Measurement and correlation of solubilities for trifluoromethylbenzoic acid isomers in supercritical carbon dioxide. Higashi, Hidenori; Iwai, Yoshio; Miyazaki, Kaoru; Ogino, Yoshiyuki; Oki, Miyuki; Arai, Yasuhiko (Department of Chemical Engineering, Faculty of Engineering, Kyushu University, Fukuoka 812-8581, Japan).Several substances are used for example 124-38-9 and 454-92-2 which are their cas registry numbers. Journal of Supercritical Fluids, 33(1), 15-20 (English) 2005 Elsevier B.V. CODEN: JSFLEH. ISSN: 0896-8446. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) Section cross-reference(s): 69 The solubilities of 2-, 3- and 4-trifluoromethylbenzoic acids in supercrit. carbon dioxide were measured at 308.2, 313.2 and 323.2 K by a flow-type app. The pressure range of the measurement was from 9 to 23 MPa. The enhancements of soly. by fluorination were markedly obsd. for 2- and 3-trifluoromethylbenzoic acids. The solubilities of 4-trifluoromethylbenzoic acids are almost the same as the known soly. of 4-methylbenzoic acid. The exptl. data were correlated by the Peng-Robinson equation of state. The correlated results show good agreement with the exptl. data by adjusting binary interaction parameters. The results can represent the tendency of soly. enhancement. The interaction parameter between carbon dioxide and 3-trifluoromethylbenzoic acid is smaller than that between carbon dioxide and 2-trifluoromethylbenzoic acid or methylbenzoic acid isomers. While the estd. sublimation pressure for 4-trifluoromethylbenzoic acid is smaller than those for the other compds., the solubilities of 4-trifluoromethylbenzoic acids are almost the same as those of 4-methylbenzoic acid. The interaction parameter between carbon dioxide and 4-trifluoromethylbenzoic acid show the neg. values. This fact indicates that the interaction between carbon dioxide and 4-trifluoromethylbenzoic acid is stronger than those between carbon dioxide and the other compds. .
