Simultaneous stereoanalysis of 2-alkyl-branched acids, esters and alcohols using a selectivity-adjusted column system in multi-dimensional gas chromatography: Simultaneous stereoanalysis of 2-alkyl-branched acids, esters and alcohols using a selectivity-adjusted column system in multi-dimensional gas chromatography. Karl, Volker; Schmarr, Hans Georg; Mosandl, Armin (Inst. Lebensmittelchem., Johann Wolfgang Goethe-Univ., Frankfurt/Main W-6000, Germany). J. Chromatogr., 587(2), 347-50 (English) 1991. CODEN: JOCRAM.Several reagents with their cas registry numbers 10307-61-6 and 616-16-0 are used here. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The direct and simultaneous stereodifferentiation of 2-methylbutanoic acid, 2-methylbutanoic acid Me and Et esters and the corresponding alc. 2-methylbutane-1-ol from apple aroma exts. was achieved by selectivity-adjusted multidimensional gas chromatog. with perethylated b-cyclodextrin as the chiral stationary phase. Extn. was with pentane-CH2Cl2 (2:1). Heart cutting from a nonchiral precolumn (methylsilicone PS-255) was used. Insertion of a nonchiral main column (3m ′ 0.32 mm fused silica capillary coated with DB-1701) improved accuracy. .

Fenxi Huaxue, 34(8), 1179-1182 (Chinese) 2006 Kexue Chubanshe. CODEN: FHHHDT. ISSN: 0253-3820. DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) Real-time assessment of enantiomeric excess (e.e.) was crit. to decisions related to possible product optical purity. Based on the principle that the rotation of the single enantiomer was proportional to its concn. under the certain circumstance, combined HPLC with online polarimetric detector, a new procedure was developed for real-time e.e. measurement. The prepn. of (S)-2-methyl-1-butanol by the porcine pancreatic lipase-catalyzed transesterification was used as example to demonstrate the availability of the procedure. 9001-62-1 and 616-16-0 are just another two chemicals used in this study. The results were compared with those by normal measurement. The procedure was fast and could provide a general measure for optimizing chiral prepn. .
