N-methylpyrrolidone (NMP) market demand is growing and industry development is accelerating

N-Methylpyrrolidone (NMP), also known as 1-methyl-2-pyrrolidone, has a chemical formula of C5H9NO and is an organic compound. N-methylpyrrolidone appears as a colorless to light yellow transparent liquid with a slight ammonia odor. It is soluble in various organic solvents such as acetone and ether, and is almost insoluble in carbon disulfide. N-methylpyrrolidone has the advantages of good chemical stability, high solubility, and good thermal stability, and has broad application prospects in fine chemicals, electronics and electrical fields.

The preparation methods of N-methylpyrrolidone include 1,4-butanediol dehydroamination method, mixed amine method, and monomethylamine (MMA) method. The 1,4-butanediol dehydroamination method refers to using 1,4-butanediol (BDO) and alkyl amine as the main raw materials, and after preheating, mixing, catalysis, dehydrogenation, amination and other processes, the final product is produced. The finished product is obtained; the mixed amine method uses γ-butyrolactone (GBL) and mixed amine as the main raw materials, and the finished product is obtained through a mixed reaction. This method has the advantages of low production cost and good finished product quality, and is the mainstream preparation of N-methylpyrrolidone. method.

The main raw material of N-methylpyrrolidone is 1,4-butanediol (BDO), which accounts for nearly 50% of its production cost. The molecular formula of BDO is C4H10O2, which is an organic compound. BDO is an important fine chemical and organic chemical raw material and is widely used in many fields. In recent years, driven by market demand, my country’s BDO output has maintained a steady growth trend. In 2022, my country’s BDO output will reach 1.912 million tons, setting a record high. The advantages of raw materials have laid a good foundation for the development of my country’s N-methylpyrrolidone industry.

The main application fields of N-methylpyrrolidone include fine chemicals, electronics and electrical, etc. In the electronic and electrical field, N-methylpyrrolidone can be used to produce liquid crystal polymer materials, lithium-ion battery electrode auxiliary materials, photoresist removal fluids, circuit board cleaners, etc. Benefiting from the accelerated development of my country’s lithium-ion battery industry, the market demand for N-methylpyrrolidone is increasingly strong. According to the “2023-2028 China N-Methylpyrrolidone (NMP) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that my country’s N-methylpyrrolidone market size will reach 7.84 billion yuan in 2022.

There are many N-methylpyrrolidone manufacturers in my country, and the market competition is fierce. Zhejiang Liansheng Chemical Co., Ltd., Binzhou Yuneng Chemical Co., Ltd., and Shandong Changxin Chemical Technology Co., Ltd. are the leading N-methylpyrrolidone companies in my country. Changxin Chemical is the largest supplier of N-methylpyrrolidone in my country. At present, the company has completed the industrial layout of N-methylpyrrolidone, and its production capacity is expected to exceed 800,000 tons by 2025.

Industry analysts said that N-methylpyrrolidone has a wide range of applications, and as the lithium-ion battery industry continues to gain momentum, its market demand increasingly prosperous. Attracted by the market prospects, many electronic chemical companies in my country have laid out N-methylpyrrolidone research and development tracks. It is expected that the development speed of my country’s N-methylpyrrolidone industry will further accelerate in the future.
