What kind of chemical is NMP (N-Methyl-Pyrrolidone,N-Methyl-2-pyrrolidone,1-Methyl-2-pyrrolidone, Methylpyrrolidone NMP )solvent?
Follow me on:
N-Methyl-Pyrrolidone,N-Methyl-2-pyrrolidone,1-Methyl-2-pyrrolidone, Methylpyrrolidone NMP referred to as NMP solvent, is a polar aprotic transport solvent, high boiling point, strong polarity, low viscosity, strong solubility, no corrosion, small toxicity, strong biodegradation, low volatility, chemical stability, excellent thermal stability.
CASRN. : 872-50-4 Molecular formula: C5H9NO physical and chemical properties: character colorless transparent oily liquid, with a slight smell of amine. Melting point -24.4℃ boiling point 203℃ Relative density 1.0260 refractive index 1.486 flash point 95℃ Solubility with water, alcohol, ether, ester, ketone, halohydrocarbons, aromatics intersoluble.
Mainly used in petroleum chemical industry, plastic industry, medicine, pesticide, dye and lithium ion battery manufacturing and many other industries, also used in the polymer solvent and the polymerization reaction medium, such as polyamide, polyimide, PPS and other engineering plastics and aramid fiber, and also used in insulation materials, pesticides, pigments, consumer electronic products and detergent, etc.
Properties and stability of NMP solvent(N-Methyl-Pyrrolidone,N-Methyl-2-pyrrolidone,1-Methyl-2-pyrrolidone, Methylpyrrolidone ) :
1, colorless liquid, ammonia taste, this product is small toxicity. Can be miscible with water, soluble in ether, acetone and most organic solvents. Can dissolve most organic and inorganic compounds, polar gases, natural and synthetic polymer compounds.
2, chemical properties: stable in neutral solution. After 8 hours in 4% sodium hydroxide solution, 50%~70% hydrolysis occurs. In concentrated hydrochloric acid, 4-aminobutyric acid CH3NH(CH2)3COOH was hydrolyzed step by step. NMP((N-Methyl-Pyrrolidone,N-Methyl-2-pyrrolidone,1-Methyl-2-pyrrolidone, Methylpyrrolidone NMP ) solvents can form ketones or thiopyrrolidone due to carbonyl reaction.
Use: NMP solvent is widely used in deep smooth oil refining, polymer synthesis, insulation materials, pesticides, pigments and cleaning agents and other waste liquid environmental protection disposal: used, dirty waste N-methyl pyrrolidone can be through the solvent recovery machine and vacuum decompressing system can stop the recovery application. Because of its high boiling point compare with, so can’t use direct recycling method, through the vacuum pressure, reduces recycle heating temperature, ensure the quality of recycling, recycling peace progress factor has the above properties will see that the material can miscibility with water and you find heat only he dissolves in water solution heat release, similar to sulfuric acid in the water will also release a lot of heat. Supplementary heat of dissolution: refers to the thermal effect generated when a solute of a certain quality is dissolved in a solvent at a certain temperature and pressure (usually the standard state of temperature 298K and pressure 100kPa). Equal to the amount of heat emitted or absorbed by a mole of solute dissolved in approximately a volume of solvent.
Promising prospects: Lithium ion battery is an internationally recognized ideal chemical energy, with the advantages of small volume, large capacity and high voltage. It is widely used in mobile phones, portable computers and other electronic products. The expanding range of electric vehicles will bring greater development space for lithium ion battery in the future.
Explosive growth: in 2009, the global output of lithium ion batteries was about 3.05 billion, and the total battery capacity was about 15000WMh. The data show that the lithium battery capacity of electric vehicles reached 14000WMh in 2013, equivalent to 93% of the global capacity of small lithium batteries in 2009: In 2018, the capacity of lithium-ion batteries for electric vehicles reached 45,000WMH, nearly three times that of small lithium-ion batteries in 2009.
