From the perspective of development prospects, although biphenyl belongs to a small number of chemical products, but its application is extremely wide, involving medicine, pesticides, printing and dyeing, electronic chemistry and many other fields.
PCB is composed of two separate benzene, polycyclic aromatic hydrocarbons appearance is white or light yellow scaly crystalline, has a unique aroma, insoluble in water, acid and alkali, soluble in alcohol, ether, benzene and other organic solvents, halogenation, nitration, sulfonated can occur, such as hydrogenation reaction, generated by reaction can generate 2 - diphenic acid, 4 - diphenic acid such as biphenyl derivatives. As an important organic raw material, biphenyl is widely used in thermal oil, medicine, pesticides, dyes, liquid crystal materials and other fields.
From the point of production process, the PCB industry mainly adopts pure benzene high temperature condensation method (including pure benzene vaporization, biphenyl synthesis, condensation, crude distillation, distillation process) biphenyl industrialized production, namely, pure benzene as raw material for making PCB, the thermal cracking dehydrogenation has high purity, low impurity content, easy industrial mass production etc. In terms of capacity and output, in 2021, the capacity of China's biphenyl industry is 27,200 tons, and the output is 230,000 tons.
According to the "2022-2026 China Biphenyl Market Feasibility Study Report" released by The New Sijie Industry Research Center, biphenyl is mainly used in thermal oil, organic synthesis, medicine, especially in the field of thermal oil, the application proportion is relatively high. In addition, biphenyl also has certain applications in lithium-ion batteries, liquid crystal electronics, pesticides and other fields, but the proportion is relatively low. In 2021, the demand for biphenyl in thermal oil, organic synthesis and medicine will account for 30.4%, 26.1% and 10.7% respectively.
From the perspective of market competition, at present, there are few biphenyl industry manufacturers in China, and the market competition is relatively moderate. Representative enterprises 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, the capacity share of Shexian Jindong Economic and trade Co., Ltd. is 44.1%.
From the perspective of development prospects, although biphenyl belongs to a small number of chemical products, but its application is extremely wide, involving medicine, pesticides, printing and dyeing, electronic chemistry and many other fields. In terms of specific application, the heat conduction oil produced from biphenyl and its derivatives can be used in the fields of photothermal power generation and industrial production. High purity biphenyl can be used to produce drugs for treating rheumatoid arthritis, osteoarthritis and other diseases; Biphenyl has been widely used in lithium battery electrolyte 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 industry has a good prospect of development.
According to industry analysts of New Sijie, in the future, with the development of chemical industry, medicine, optoelectronics, pesticide, printing and dyeing, electronics and other industries, the demand for biphenyl in organic synthesis, thermal oil, pharmaceutical and other fields will continue to grow, especially the demand for thermal oil, electronic materials, will become an important driving force for the growth of biphenyl demand.
