Pyridine, an organic compound with the chemical formula C5H5N, is a six-membered heterocyclic compound containing a nitrogen heteroatom. It can be regarded as a compound in which one (CH) in the benzene molecule is substituted by N, so it is also called nitrobenzene. It is a colorless or slightly yellow liquid with a stench.

Appearance: colorless liquid
Solubility: Miscible with water, alcohol, ether, petroleum ether, benzene, oil and other solvents
Chemical properties:
Pyridine and its derivatives are more stable than benzene, and their reactivity is similar to that of nitrobenzene. Typical aromatic electrophilic substitution reactions occur at the 3 and 5 positions, but the reactivity is lower than that of benzene, and nitration, halogenation, sulfonation and other reactions are generally not easy to occur. Pyridine is a weak tertiary amine that can form water-insoluble salts with various acids (picric acid or perchloric acid, etc.) in ethanol solution. The pyridine used in industry contains about 1% of 2-methylpyridine, so it can be separated from its homologues by taking advantage of the difference in salt-forming properties. Pyridine can also form crystalline complexes with various metal ions. Pyridine is easier to reduce than benzene, such as reducing to hexahydropyridine (or piperidine) under the action of metal sodium and ethanol. Pyridine reacts with hydrogen peroxide and is easily oxidized to N-pyridine oxide.
Application
It is used in the manufacture of vitamins, sulfonamides, pesticides and plastics; it can also be used as an alkaline solvent, and it is also an excellent solvent for deacidification and acylation reactions; it can also be used as a carbonyl group for polymerization, oxidation, and acrylonitrile. It can also be used as a catalyst for chemical reactions, etc.; it can also be used as a silicone rubber stabilizer, a raw material for anion exchange membranes, etc.

The rotary vane vacuum pump is an oil-sealed rotary displacement pump. The outlet valve is oil-sealed. The inlet valve is designed as a vacuum safety valve that is always open during operation. It can be used independently ,which also can be as booster pump, diffusion pump , molecular pump and titanium pump's pre-pump. Also used as electronic devices produce, vacuum drying, filtration ,welding, metal smelting, etc.
2XZ-2 rotary vane vacuum pump is mainly composed of pump body, rotor, rotary vane, end cover, spring, etc. Installing a rotor in rotary vane pump cavity, the outer circumference of the rotor is tangent to the inner surface of the pump chamber, the rotor slot inner is fitted with two rotary vane with springs. When it is rotating,centrifugal force and the spring tension makes the top of rotary vane keep contact with pump chamber wall, the rotating rotor drives the rotary vane to slide along the inner wall of the pump cavity.
