Relevant research continues to deepen, and large-scale production and application of ionic liquids are just around the corner.

Compared with European and American companies, my country’s ionic liquid research started late, and the current market is still in the early stages of development. In the domestic market, ionic liquid-related production companies include Zhejiang Lande, Jiangxi Jinkai Chemical, Henan Lihua Pharmaceutical, Shenzhen Gulicheng, Enterprises such as Huizhou Ailiron and Moni Chemical (Shanghai), and related research institutions include Lanzhou Institute of Chemical Physics, Peking University Green Catalysis Laboratory, East China Normal University Ionic Liquid Research Center, etc.

Ionic liquid (IL for short), also known as ionic liquid and low-temperature molten salt, refers to a type of molten salt that is liquid below 100°C or at room temperature. It is generally composed of organic cations and inorganic anions. There are many types of ionic liquids. According to different cations, ionic liquids can be divided into pyrrole salts, imidazole salts, quaternary ammonium salts, quaternary phosphonium salts, pyrrolidine salts, etc.; according to different anions, ionic liquids are divided into aluminum trichloride type, non-ionic liquids. Aluminum trichloride type and other special types.

Ionic liquids are odorless, have few production by-products, and have excellent thermal stability and conductivity. They can be used as green catalysts and solvents to replace traditional solvents. Up to now, the development of ionic liquid technology has experienced three major changes. In the 21st century, with the continuous improvement of basic research, the research and development process of third-generation ionic liquids has accelerated, and functionalization is its main research direction. Due to the diversity of cations and anions, ionic liquid materials with multiple functions can be designed by changing the ratio combination.

According to the “2021-2025 China Ionic Liquid Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, ion Liquids achieved industrial production in 2010. Attracted by the good market prospects, the number of companies entering this field is increasing. In 2020, the global ionic liquid market will reach more than US$32 million. However, due to the strict blockade of core technologies, the ionic liquid market is highly concentrated, with BASF, IOLITEC GmbH, Germany’s Solvionic, Merck and other companies occupying major market shares.

Early applications of ionic liquids were in the field of electrochemistry research. In recent years, as research continues to deepen, the applications of ionic liquids have gradually expanded to fields such as displays, nuclear waste treatment, lubricating materials, photovoltaics, lithium batteries, medicine, and electronic skin. Ionic liquids are in line with the development direction of modern green and sustainable manufacturing. With breakthroughs in related technologies and expansion of application scenarios, large-scale production and application of ionic liquids is just around the corner.

Industry Analysis Shengsheng said that as an emerging industry, the ionic liquid market is still in the early stages of development. Due to the strict blockade of core technologies, the global market is still Dominated by international giants. There are many types of ionic liquids with rich application scenarios. At the same time, ionic liquids are also green and environmentally friendly, which meet the needs of sustainable development of modern industry. Against the background of increasingly strict environmental protection supervision, the future market prospects of ionic liquids are promising.
