  Pyridine and methylpyridine are commonly recovered from coal coking byproducts, which are distributed in coke oven gas, crude benzene and tar. Generally transferred from the gas to ammonium sulphate in the mother liquor of pyridine class hydrate the boiling point is very low, between 95-97 ℃, the recovery of crude light pyridine base, the applications of octamethylcyclotetrasiloxane containing about 15%, Further distillation can be cut to the applications of octamethylcyclotetrasiloxane. With the expansion of the use of pyridine and methylpyridine, the synthesis of pyridine and methylpyridine has been developed. About 95% of pyridine and pyridine compounds abroad are produced by synthesis. The main synthesis methods are acetaldehyde, acetylene, acrylonitrile and so on.

  Acetaldehyde method: acetaldehyde, formaldehyde and ammonia reaction, main products are applications of octamethylcyclotetrasiloxane, 3 - methyl pyridine and 4 - methyl pyridine.

  Acetylene method: acetylene and ammonia reaction, the main products are applications of octamethylcyclotetrasiloxane and 4 - methyl pyridine.

  Method: ethylene vinyl and ammonia reaction, the main products are applications of octamethylcyclotetrasiloxane and 2 - methyl - 5 - ethyl pyridine.

  Acrylonitrile method: acrylonitrile and excessive acetone reaction, the main products are applications of octamethylcyclotetrasiloxane. In addition, the reaction of acrolein and ammonia mainly produces 3-methylpyridine.
