Opis

General description

Pyridine (Pyr) is a nitrogen containing six membered heterocyclic compound commonly used as a base. It is a colorless liquid with a fishy odor. Pyridine moiety is present as a major component in a number of compounds like pyridine nucleotides, pyridine alkaloids, pyridine-based polymers and pyridine-containing macrocycles. It has wide application as a solvent, catalyst and as an intermediate for synthesis.[1] IR, Raman and UV spectra of pyridine has been analyzed and the values obtained were used to calculate its thermodynamic properties. Photodegradation[2] and bacterial degradation of Pyr has been studied.

Application

Pyridine may be used in the synthesis of the following:

complexes with cobalt(II) halides
pyridine-d₅, a deuterated form of pyridine
ionic liquid matrices (ILMs)[3]

Biotreatment of waste gas containing pyridine in a biofilter.

R A Pandey et al.

Bioresource technology, 98(12), 2258-2267 (2006-07-04)

Industrial waste gas emissions containing pyridine are generated from pyridine manufacturing industries, and in industrial operations where pyridine is used as a solvent, as an intermediate for synthesis and as a catalyst for a variety of applications. Pyridine has unpleasant

Photocatalytic degradation of N-heterocyclic aromatics-effects of number and position of nitrogen atoms in the ring.

Jasmeet Kaur et al.

Environmental science and pollution research international, 20(6), 3956-3964 (2013-05-08)

This study demonstrates the influences of position, number of nitrogen (N) atoms and -C-N- or -N=N- linkage present in the six membered heterocyclic compounds such as pyridine, pyrazine, and pyridazine on their photocatalytic degradation by Au, Ag, and Fe(+2) deposited
