In situ FTIR spectroscopy was used to study the interaction of pyridine-3-carbaldehyde (3PyA) with the surface of ТiO 2 and a V-Ti-O catalyst in the temperature range of 120-300°C. 3PyA interacts with Lewis and Brnsted acid sites of ТiO 2 and the V-Ti-O catalyst to form a ...
只要有红外仪就可以了啊，如果你非要做原位吸附吡啶那就需要有原位池了。我们一般都不是原位吸附吡啶的...
The USY-550-700 final sample is used for FTIR Spectra of adsorbed pyridine to study the type of acidity produced on the sample prepared. This sample is also tested in the chemical reaction as a catalyst to study the effect of acidity developed on it in the chemical reaction. The study of...

Flonicamid is a pyridine carboxamide pesticide having cyanide. For the bromination, first of all, hydrolyzed flonicamid with sodium hydroxide was done resulting in the formation of TFNA. When the resulting solution again treated with sodium hydroxide then it form hydrogen cyanide. The resulting solution...
This approach has been applied to a variety ofproblems arising following laser excitation of d6 polypyridine complexes in solution, andseveral examples are shown to demonstrate the utility of this experiment.关键词: Time-resolved infrared step-scan infrared excited state d⁶ polypyridine ...
