Roasted lamb fat: basic volatile components

Roasted lamb fat: basic volatile components. Buttery, Ron G.; Ling, Louisa C.; Teranishi, Roy; Mon, Thomas R. (WRRC, ARS, Berkeley, Calif., USA). J. Agric. 4145-93-1 is the cas registry number. This chemical is also mentioned in this article. Food Chem., 25(6), 1227-9 (English) 1977. CODEN: JAFCAU. DOCUMENT TYPE: Journal CA Section: 17 (Foods) The basic fraction from the steam-volatile oil obtained from roasted lamb fat (the main major contributor to the flavor of roasted lamb) was analyzed by a combination of glass capillary column gas chromatog. and mass spectrometry. Twelve alkylpyridines, 12 alkylpyrazines, and 2 alkylthiazoles were characterized. The major component of the basic fraction was 2-pentylpyridine [2294-76-0]. Other unusual compds. characterized included 5-methyl-2-pentylpyridine [64021-55-2], 5-ethyl-2-pentylpyridine [5328-02-9], 2-butylpyridine [5058-19-5], 2-hexylpyridine [1129-69-7], and 3-pentylpyridine [1802-20-6]. .

Selective solvent extraction of chromium(VI) using 2-hexylpyridine

Selective solvent extraction of chromium(VI) using 2-hexylpyridine. Separation from uranium, thorium, fission products and first transition series elements. Iqbal, M.; Ejaz, M. (Nucl. Chem. Div., Pakistan Inst. Nucl. Sci. Technol., Nilore, Pak.). J. Radioanal. Chem., 42(2), 313-21 (English) 1978. CODEN: JRACBN. ISSN: 0022-4081. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) The extn. behavior of trace and macroamts. of Cr(VI) from different mineral acid solns. by 2-hexylpyridine [1129-69-7] in CHCl3 was investigated. In the chloride system, the extd. species is apparently (HPyH+)2(Cr2O7)2- or HPy+(HCrO4-) for macro and trace amts. of Cr(VI), resp. Among the common anions, Cl- and SO42- have little effect on extn. <1M concn., while in the case of NO3-, there is a continuous decrease in the extn. with the increase of salt concn. in the aq. phase. The effect of ascorbate, acetate, citrate, oxalate, thiosulfate, thiocyanate ions on the extn. from 1M HCl was also examd. Sepn. factors of several elements relative to Cr(VI) are described and the sepn. of Cr(IV) from a large no. of elements was achieved.
