There are few companies in the terphenyl industry and market demand may grow year by year.

              Para-terphenyl, with the chemical formula C18H14, is an organic synthesis intermediate with white flaky crystals, soluble in hot benzene, slightly soluble in ether and carbon disulfide, and extremely insoluble in ethanol and acetic acid. Para-terphenyl is mainly used as a scintillator for the production of plastic particles and plastic flakes. It is also one of the basic intermediates for the preparation of biphenyl-based liquid crystal materials. It is also a precursor for the synthesis of antibacterial cyclic peptides (4-carboxy-para-terphenyl, CTP). Basic ingredients. In addition, p-terphenyl can also be used to prepare 4,4-dicarboxy-terphenyl (DCTP), which is the main raw material for preparing biphenyl polyamide materials.

At present, there are two main ways to prepare para-terphenyl. One is to nitrate, reduce and acetylate biphenyl to obtain para-acetamidobiphenyl, which is then reacted with dinitrogen trioxide to obtain N-nitroso-para-acetamido. Biphenyl is then obtained by reacting with benzene; the other is obtained by separating biphenyl.

At present, there are few terphenyl manufacturers in my country, and the market competition is relatively relaxed. A few companies such as Jiangsu Zhongneng Chemical Technology Co., Ltd. and Shexian Jindong Economic and Trade Co., Ltd. occupy a relatively high market share, and their product quality and technical level are at the leading level in the country. leading position. However, due to the small overall domestic demand, there has been overcapacity in the country.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on China’s Terphenyl Industry 2023-2027” released by the Industrial Research Center Although terphenyl products have a wide range of downstream applications, due to high product prices and certain limitations in downstream applications, China’s overall market demand for terphenyl is relatively small at this stage. In 2022, the domestic market demand for terphenyl will be around 10 Around tons.

Industrial researchers personnel said that in the future, benefiting from the good development trends of scintillators, laser dyes, liquid crystal materials, medicine and other industries, the above-mentioned industries The market demand for terphenyl will continue to rise, especially the growth in market demand for scintillator and laser dyes, which will drive the growth of market demand for terphenyl and become an important driving force for the growth of market demand for terphenyl, and the pharmaceutical field has a strong demand for terphenyl. The demand for terphenyl may become one of the new growth points.
