Product description

N-Methyl-2-Pyrrolidone (NMP) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability. It is used as a solvent for engineering polymers and coating resins. Additionally, the polar nature and the low surface tension of NMP makes it an excellent cleaning medium and paint stripping solvent.
Widely used in aromatics extraction, the purification of acetylene, olefin and diolefin polyvinylidene fluoride solvent, auxiliary material of lithium ion battery electrodes, synthetic gas desulfurization and refined lubricating oil,lubricating oil, antifreeze, olefin extractant, refractory engineering plastic polymerization solvent, agricultural herbicides, insulation materials, integrated circuit production,Semiconductor industry precision instruments, circuit board cleaning,PVC tail gas recovery, cleaning agent, dye additives, dispersants, etc.It is also used as a solvent for polymers and as a medium for polymerization reactions, such as engineering plastics and aramid fibers.Also can be used in pesticide, medicine and detergent and so on.
NMP is a powerful solvent with a low volatility used for a wide range of chemicals and finds its application among others in:
Petrochemical processing:
NMP is used as extraction medium in several industrial processes because of its affinity for unsaturated hydrocarbons and aromatics, for example butadiene recovery, BTX extraction, lube oil purification, As illustration for the strong selectivity of NMP towards acetylene, the table below shows the solubility of acetylene in various solvents.

    Bust the myths behind electric vehicles.

    There are three types of production processes for NMP.
    One is the pyrrolidone method, which uses pyrrolidone and halogenated alkanes as raw materials.
    The second is the synthesis of NMP under catalyst conditions.
    The third is the GBL method, which is based on γ-butyrolactone and mixed methylamine or monomethylamine.
    At present, the GBL method is mostly based on the mixture of γ-butyrolactone and monomethylamine in aqueous solution.
    GBL method is generated by mixing γ-butyrolactone and monomethylamine aqueous solution in a tubular mixer, preheated by a tubular preheater, and reacted in a tubular reactor for 1.5-2.0 hours at a high temperature of 260-290℃ and a pressure of 7.5-8.5Mpa.
