There are not many companies in the biphenyl industry, but there is great potential for future development.

Biphenyl is a polycyclic aromatic hydrocarbon composed of two independent benzene rings. It appears as white or yellowish scaly crystals and has a unique fragrance. It is insoluble in water, acid and alkali, and soluble in organic solvents such as alcohol, ether and benzene. Reactions such as halogenation, nitration, sulfonation, and hydrogenation can occur, and biphenyl derivatives such as 2-biphenylcarboxylic acid and 4-biphenylcarboxylic acid can be generated through the reaction. As an important organic raw material, biphenyl is widely used in thermal oil, medicine, pesticides, dyes, liquid crystal materials and other fields.

From the perspective of production technology, the biphenyl industry mainly uses pure benzene high-temperature condensation method (including pure benzene vaporization, biphenyl synthesis, condensation, crude distillation, rectification and other processes) for industrial production of biphenyl, that is, pure benzene is used as raw material and heated The production of biphenyl through cracking and dehydrogenation has significant advantages such as high purity, low impurity content, and easy industrial large-scale production. From the perspective of production capacity and output, in 2021, my country’s biphenyl industry has a production capacity of 27,200 tons and an output of 23,000 tons.

According to the “China Biphenyl Market Feasibility Research Report 2022-2026” released by the Industrial Research Center, biphenyl is mainly used in The thermal oil, organic synthesis, and pharmaceutical fields, especially the thermal oil field, have a relatively high proportion of applications. In addition, biphenyl also has certain applications in lithium-ion batteries, liquid crystal electronics, pesticides and other fields, but its proportion is relatively low. In 2021, the demand for biphenyl in the thermal oil field will account for 30.4%, the demand for biphenyl in the organic synthesis field will account for 26.1%, and the demand for biphenyl in the pharmaceutical field will account for 10.7%.

From the perspective of market competition, there are currently few manufacturing companies in the biphenyl industry in my country, and market competition is relatively relaxed. The more representative companies include Shexian Jindong Economic and Trade Co., Ltd., Jiangsu Zhongneng Chemical Technology Co., Ltd., etc. Among them, Shexian Jindong Economic and Trade Co., Ltd. has a relatively large biphenyl production capacity and is a leading enterprise in the domestic biphenyl industry. In 2021, Shexian Jindong Economic and Trade Co., Ltd. has a production capacity share of 44.1%.

From the perspective of development prospects, although biphenyl is a niche chemical product, its applications are extremely wide, involving many fields such as medicine, pesticides, printing and dyeing, and electronic chemistry. In terms of specific applications, thermal oil produced from biphenyl and its derivatives can be used in fields such as photothermal power generation and industrial production; high-purity biphenyl can be used to produce drugs for the treatment of rheumatoid arthritis, osteoarthritis and other diseases. ; Biphenyl has important applications in lithium battery electrolytes due to its excellent thermal stability and relatively low vapor pressure; biphenyl is also widely used in liquid crystal materials. Based on this, the biphenyl market still has great potential in the future, and the prospects for industry development are good.

Industrial analysts said that in the future, with the development of chemical, pharmaceutical, optoelectronic, pesticide, printing and dyeing, electronics and other industries, organic synthesis, The demand for biphenyl in the fields of thermal oil and pharmaceuticals continues to grow, especially the growth in demand for thermal oil and electronic materials, which will become an important driving force for the growth of biphenyl demand.
