With the support of national policies, the development of butyrolactam (2-pyrrolidone) industry has accelerated

Butyrolactam, also known as 2-pyrrolidone and 2-pyrrolidone, has a chemical formula of C4H7NO and is an organic compound. Butyrolactam appears as a colorless liquid, miscible in carbon tetrachloride, water, ether, alcohol and benzene, but insoluble in petroleum ether. Butyrolactam is a carbon-containing compound with the advantages of good chemical stability, biodegradability, and recyclability. It has broad application prospects in the fields of inks, synthetic resins, chemicals, pesticides, electronics, and electrical appliances.

In January 2023, six departments including the Ministry of Industry and Information Technology jointly issued the “Three-Year Action Plan to Accelerate the Innovative Development of Non-Food Bio-based Materials”. The document clearly stated that carbonaceous chemicals such as butyrolactam, succinic acid, and sebacic acid should be encouraged, as well as polymers. The development of carbonaceous polymer industries such as carbonate, polyamide, and polylactic acid will further improve the non-food bio-based materials industry system. Benefiting from national policy support, the development speed of my country’s butyrolactam industry is expected to further accelerate.

The main raw materials of butyrolactam are acrylonitrile and hydrocyanic acid. Acrylonitrile (AN) is an organic compound that appears as a colorless liquid. It has the advantages of high strength, high modulus, high temperature resistance, and chemical resistance. As an important chemical raw material, it is used in synthetic rubber, synthetic polymers, and synthetic fibers. It is widely used in fields such as synthetic resin and synthetic resin. my country is a major producer of acrylonitrile, and its products are sold overseas while meeting the needs of the local market. The advantages of raw materials have laid a good foundation for the development of my country’s butyrolactam industry.

According to the “2023-2028 China Butyrolactam (2-Pyrrolone) Industry Market In-depth Research and Development Prospects Forecast Report》shows that butyrolactam has broad application prospects in the fields of fibers, inks, synthetic resins, chemicals, pesticides, electronics and electrical appliances. In the field of fiber, adding butyrolactam to spinning materials can greatly improve the hygroscopicity of the material; in the field of chemical industry, butyrolactam, as an important organic synthetic raw material, can be used to produce polypyrrolidone, polyvinylpyrrolidone and nylon. 4, etc.; in the field of electronics and electrical, butyrolactam can be used as an electrolyte to prepare cathode materials for lithium metal batteries.

my country’s butyrolactam market is dominated by small and medium-sized enterprises, and the industry concentration is low. Jiangsu Tianzhi Chemical Co., Ltd., Shandong Changxin Chemical Technology Co., Ltd., Jingrui Electronic Materials Co., Ltd., etc. are the main players in my country’s butyrolactam market. In the future, with technological advancement, the concentration of my country’s butyrolactam industry is expected to increase.

Industry analysts said that butyrolactam, as an important raw material for organic synthesis, is widely used in many fields. In the future, driven by positive factors such as national policy support and the improvement of independent research and development capabilities of local enterprises, the development speed of my country’s butyrolactam industry will further accelerate. In terms of market competition, my country’s butyrolactam industry has low concentration. In the future, companies with independent research and development capabilities for high-performance products will occupy a larger share of the market.
