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.

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.

FAQ:
1. Are you a manufacturer or a trading company?
We are engaged in casting machinery manufacturing professional supplier
2. How can I get some samples?Â
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the courier cost, and the charge will be deducted from the payment for formal order.
Â
3. Can you make casting according to our drawing?
Yes, we can make casting according to your drawing, 2D drawing, or 3D cad model. If the 3D cad model can be supplied, the development of the tooling can be more efficient. But without 3D, based on 2D drawing we can still make the samples properly approved.
Â
4. Can you make casting based on our samples?
Yes, we can make measurement based on your samples to make drawings for tooling making.
Â
5. What's your quality control device in house?
We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the casting detect under the surface of casting.
