DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The contents in some carbonyl compds. in "Kacheti" wine were detd. by GC-MS after analytes derivatization. Pentane-extd. carbonyls react with pentafluorophenylhydroxylamine and then with mixt. of pyridine/borane. The GC anal. uses temp. program and MS detection in aimed at m/z = 181 ions ay 35 eV. The levels of pentanal, furfural, pentenal, b-cyclocitral, 2-nonanone, and 2-undecanone in the Kacheti wine were detd. .

DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23, 51, 67 The catalytic conversion of methane (C1) into higher hydrocarbons using n-pentane (n-C5) as co-reactant over Zn/H-ZSM-11 zeolite material was studied. The aroms. yield was very high, achieving values of over 40 mol% at 500 °C and w/f = 30 g h mol-1 with a C1/(C1 + C5) molar fraction (X;C1) = 0.30. Contact time and time-onstream effects on the product distribution were analyzed in detail in order to obtain information about the evolution of different species. The C1 conversion was as high as 30 mol% without COx reaction products.
