Activity Comparison of MCM-41 and V-MCM-4 Catalysts for Ethanol Selective Oxidation and DRIFTS Analysis
(Walter De Gruyter GMBH, 2009)The activity of a V-MCM-41 catalyst with a V/Si molar ratio of 0.04 was compared with the activity of a pure MCM-41 catalyst and some DRIFTS studies were performed in order to understand the mechanism of selective oxidation ... -
The bioactive essential oil of Heracleum sphondylium L. subsp ternatum (Velen.) Brummitt
(Walter De Gruyter GMBH, 2003)The essential oil of Heracleum sphondylium L. subsp. ternatum (Velen.) Brummit (Umbelliferae) was isolated from crushed seeds by means of hydrodistillation and analyzed by GC and GC/MS. Major components were identified as ... -
Selective photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde in organic-free water in a continuous annular fixed bed reactor
(Walter De Gruyter GMBH, 2007)Photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde was performed in water organic-free solutions by using a fixed bed continuous photoreactor containing Pyrex beads on which a TiO2 home prepared photocatalyst ... -
Thalictricoside, a new phenolic compound from Thalictrum orientale
(Walter De Gruyter GMBH, 2003)From the underground parts of Thalictrum orientale Boiss., a new phenolic compound 1 was isolated in addition to one known cyanoglycoside, lithospermoside (2). For the structure elucidation of all compounds, 1D- and 2D-NMR ... -
Vibrational spectroscopic and conformational studies of 1-(4-pyridyl)piperazine
(Walter De Gruyter GMBH, 2010)Possible stable conformers of the 1-(4-pyridyl)piperazine (1-4pypp) molecule were experimentally and theoretically studied by FT-IR and Raman spectroscopy. FT-IR and Raman spectra were recorded in the region of 4000-200 ...
