Cyclopentene has broad application fields but a small market size

Cyclopentene (CPE) is an important fine chemical intermediate, appearing as a colorless, irritating liquid. Cyclopentene is soluble in ethanol, ether, benzene and petroleum ether, but insoluble in water. Steam and air form explosive mixtures. Cyclopentene is a hazardous chemical, flammable and explosive, and difficult to produce, transport and store. Therefore, industry entry barriers are high.

As one of the fine chemical intermediates, cyclopentene can undergo ring-opening metathesis polymerization (ROMP) reaction to generate polycyclopentene elastomer. In addition, cyclopentene can also be used to prepare cyclopentanol, cyclopentanone, and chlorinated cyclopentene. Products such as pentane, bromocyclopentane, cyclopentanoic acid, ketamine, cyclopentylphenol, cyclopentanediol, polycycloolefin polymers, etc. Rubber produced with cyclopentene as raw material has good wear resistance , fuel saving and aging resistance. The downstream applications of cyclopentene are generally divided into two parts: comonomer and organic synthesis. Comonomer is the main application scenario, accounting for more than 70%.

According to the “2023-2027 China Cyclopentene Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center , although cyclopentene is widely used, the application scale in various fields is limited, so the market size is small. In 2021, my country’s cyclopentene market size is about 51 million yuan, and the industry output is about 5.9,000 tons. It is expected that in the next five years, my country’s cyclopentene market will be in a growth trend, but the growth rate will be relatively stable.

In industrial production, dicyclopentadiene is often obtained by cracking carbon 5 double distillation, and then cyclopentadiene is obtained, and cyclopentene is obtained by catalytic hydrogenation over a catalyst. In recent years, thanks to advances in preparation technology and upgraded market demand, cyclopentene has achieved significant improvements in purity, performance, quality and other aspects. In terms of purity, cyclopentene with a purity of ≥99.0% has become a mainstream product in the market, accounting for more than 70.5%.

In terms of production, globally, cyclopentene production capacity is mainly distributed in China, Japan and other regions. The main manufacturers include Japan Zeon, Shanghai Gonghe Chemical, Zhejiang Alpha Chemical Technology, Shanghai Pelko Chemical Materials, Huangshan Bashui Chemical industry, etc. my country is a major producer of cyclopentene in the world. In recent years, due to stricter environmental protection/safety production policies, shortage of raw material supply, and backward production capacity gradually withdrawing from the market, the concentration of the cyclopentene market has increased.

Industry analysts said that cyclopentene has a wide range of applications, and its end applications involve electronics, medicine, spices, rubber and other fields. , but due to limited application demand in various fields, the cyclopentene market is small. my country is a major producer of cyclopentene in the world. In recent years, thanks to technological progress and demand upgrading, the purity of cyclopentene has been greatly improved, and the industry has gradually upgraded to high-end, environmentally friendly, high-purification and centralization directions.
