About the Use of NMP

NMP, full name N-methylpyrrolidone, is an organic compound with the chemical formula C5H9NO. It is a colorless to light yellow transparent liquid with a slight ammonia smell. It is miscible with water in any ratio and is soluble in ether, acetone, esters, and halogens. Various organic solvents such as hydrocarbons and aromatic hydrocarbons are completely mixed with almost all solvents.
NMP is widely used in lithium batteries, medicine, pesticides, pigments, cleaning agents, insulation materials and other industries, and is one of the most commonly used lithium battery auxiliary materials. As a solvent, it is an auxiliary material for the production of lithium-ion battery electrodes. It can also be used as a solvent for the separation and recovery of synthesis gas, aromatics and butadiene from hydrocarbon cracking gas, refinery gas and natural gas.
In addition, NMP can also be used to remove aromatic hydrocarbons from lubricating oil fractions and alkanes from kerosene fractions. It is used to produce acrylonitrile solvents, spinning solvents, polyurethane solvents, polyvinyl chloride solvents, epoxy resin solvents, synthetic rubber solvents, Essential material for pesticide extraction solvent. Moreover, it is also a key material in the production of pharmaceutical intermediates, insulation materials, metal surface coatings, synthetic fiber solvents, and fine chemicals for integrated circuit production.

NMP (N-methylpyrrolidone) has some other important application areas:

In surface coatings, NMP is a non-corrosive, high-boiling point solvent with excellent solvent properties and chemical stability. It improves the performance of many surface coating systems and is an excellent solvent for coating raw materials such as acrylates, epoxy resins, polyurethanes, PVC systems, enamel wire-based polyamides, water-based coatings and printing inks.
Among wire materials, NMP has good solubility for polycarboxylic acids and their anhydrides, so it has important applications in the manufacturing process of thermosetting insulating coatings.
In the plastics industry, NMP is widely used as an industrial solvent for natural and synthetic plastics, waxes, resins and various paints.
In terms of chemical production agents, NMP is widely used in large-scale recovery and purification of hydrocarbon solvents, using its high solubility to increase volatility.
In agrochemicals, NMP can be used as a solvent or co-solvent in the formulations of pesticides, fungicides, herbicides, and seed control treatments.
In terms of cleaning and degreasing, NMP has been successfully used as a paint removal, cleaning and degreasing formulation due to its high solubility in plastics, resins, oils and greases.
In other fields, NMP is also used as additives and dispersants in lubricant refining, lubricant antifreeze, syngas desulfurization, PVC tail gas recovery, high-end coatings, inks, pigments, etc., as well as from natural gas or light naphtha. Acetylene recovery from oil thermal cracking gas, etc.
In short, NMP is a very important organic solvent with wide applications in many fields.

Please note that although NMP is widely used in many fields, it also has certain toxicity and irritation, so appropriate safety measures need to be taken during use.
