1-Methyl-2-Pyrrolidinone Uses

1. Industrial high quality: lubricating oil refining, lubricating oil antifreeze, synthetic gas desulfurization, digital insulation products, farming herbicides, chemical devices, PVC tail gas healing, ingredients as well as dispersants for the production of high-quality treatments, inks, and additionally pigments. For instance, it is utilized to draw out aromatics in lubricating oil to accomplish the feature of refining lubricating oil; due to the fact that 1-Methyl-2-Pyrrolidinone has a large solubility in material, it can be made use of as a solvent for material processing to make layers, flooring paints, varnishes, and composite finishings. Film forming, integrated circuit enameled cable television insulation materials, fiber products as well as also adhesives and also other things.
2. Normal top quality: Removal and likewise healing of conventional all-natural raw materials, such as acetylene emphasis as well as extraction of butadiene, isoprene, aromatics, and so on. It can be made use of as a solvent for recouping acetylene from gas or light naphtha thermal cracking gas, as well as the pureness of redeemed as well as concentrated acetylene can reach 99.7%; as an elimination representative for separating along with redeeming high-purity butadiene from split C4 hydrocarbons, the healing rate can get to 97% %, the recovery of butadiene has a purity of 99.7%. It is made use of as an extractant for recouping high-purity isoprene in the fracturing of C5 hydrocarbons. The recuperation of isoprene reaches a purity of 99%. With reduced vapor pressure, the loss price of removal representative is lowered as well as the recovery rate of aromatics is high during the procedure.
3. Reagent quality: degreasing, degreasing, dewaxing, polishing, corrosion evasion, paint removal, and so on for industries such as incorporated circuits and hard disks that need rigorous control of steel ions as well as pieces, such as photoresist eliminator, IC semiconductor market Cleansing of precision tools, LCD liquid crystal materials, PCB published circuit card, along with hard disks; and also solvents produced in the pharmaceutical field such as man-made kidney practical membrane layer liquid and seawater desalination membrane layer liquid.

1-Methyl-2-Pyrrolidinone Production Method

There are presently three manufacturing procedures for 1-Methyl-2-Pyrrolidinone, one is the pyrrolidone method using pyrrolidone and also halogenated alkanes as basic materials, the various other is the synthesis of 1-Methyl-2-Pyrrolidinone under stimulant conditions, and also the third is γ-butyrol GBL technique with ester and also blended methylamine or monomethylamine as raw materials. Today, the combined GBL method of γ-butyrolactone and also monomethylamine aqueous solution is primarily made use of. The GBL approach is to blend γ-butyrolactone and monomethylamine liquid remedy in a tubular mixer, pre-heat it with a tubular preheater, and also warm it in the column at a heat of 260-290 ° C and a stress of 7.5-8.5 Mpa. 1.5-2.0 hrs of reaction in a tubular reactor.

1-Methyl-2-Pyrrolidinone Development Status

my nation’s 1-Methyl-2-Pyrrolidinone has decades of advancement history. Given that 2008, my nation’s NMP market has experienced eruptive development. Driven by its downstream items, a multitude of tools have actually shown up in a short amount of time, driving my country’s NMP manufacturing Rapid development in size. The advancement of these years has made my N-methylpyrrolidone NMP manufacturing range rank initially worldwide, and also the items are exported to Japan, South Korea, The United States And Canada, Europe, the Middle East and other areas.

According to the study, in 2021, China’s NMP output went beyond 500,000 tons, with no imports and almost 100,000 lots of exports. China’s obvious usage of NMP was around 400,000 lots. In the past few years, China’s NMP usage has shown a fast development of more than 30%, and it is also a product with a faster development rate in China’s chemical industry. Under such an advancement trend, the market share of NMP in my nation will certainly remain to grow rapidly, and also the future usage will certainly be significant.

The manufacturing procedure of 1-Methyl-2-Pyrrolidinone has actually additionally been discussed over. At present, the majority of the production in my nation is still GBL, and also the manufacturing of GBL is based on BDO as the raw material. The upstream items of BDO can be traced back to maleic anhydride and n-butane, as well as n-butane is presently Products that are popular as well as concerned about product chain expansions. If the venture can have the supporting production from n-butane to downstream items, after that N-methylpyrrolidone NMP will have the advantage of the overall industrial chain.
