Lvba’s Dursban technical production permit granted, pyridine use in downstream extended

 

It is reported that Chinese domestic Dursban production mostly uses trichloro-acetic chloride process, which is operated in a poor environment and results in low quality and low yield while generating large amount of wastes. The cost of waste treatment is high, which adds up to a high cost of production and restrains the mass production. Lvba’s Dursban production is based upon the high-content tetrachloropyridine being used as raw material, which is synthesized via high-performance catalyst and ethyl chloride condensation, resulting in production of high quality Dursban. The new synthesis process enables achievement of high yield and high technical content while the technical material appears to be white colored, which is much improved compared with the traditional product. Furthermore, the process reduces considerable amount of waste discharge, leading to a lower cost of production of the technical material.

 

China has currently an annual pyridine production capacity of 120,000 tons. Pyridine is an important intermediate for a large variety of pesticide and pharmaceuticals, as well as a key intermediate for paraquat industry upstream. The destined prohibition of paraquat will cause a further impact to the already-excessive capacity of pyridine industry. Thetetrachloropyridine-based Dursban production process of Shandong Lvba not only extends the pyridine use in the downstream chain, but also broadens the company’s pyridine pesticide portfolio. In the meantime, it helps to solve the pyridine oversupply problem to the benefit of sound development of pyridine industry on a long-term basis.

 

Dezhou Lvba is a wholly-owned subsidiary of Shandong Lvba, being a prime production base in the industry chain of Shandong Lvba. At present, the production base is in possession of a 10,000-ton tetrachloropyridine process-based Dursban production facility. Shandong Lvba has also invested a 43,000-ton pyridine chlorination project in Weifang City, of which the 30,000-ton tetrachloropyridine production is dedicated to supporting Dursban production.
