Methyl pyrrolidone NMP N-methylpyrrolidone cleaning chemical reagent supply

Description :

　　Chinese name: N-methylpyrrolidone, English name: 1-Methyll-2-pyrrolidone, Chinese alias: NMP; 1-Methyl-2-pyrrolidone; N-methylpyrrolidone (industrial grade); N-methylpyrrolidone (electronic grade); N-methylpyrrolidine

　　Toxicity: LD50 (rat) estimate of 8200 mg/kg. It has strong permeability. When used as a pesticide dispersant, it is easy for pesticides to penetrate the skin and enter the human body, causing poisoning. Please take precautions In recent years, new research in Europe and the United States has shown that this solvent may have accumulated toxicity or carcinogenic potential, but the conclusion is not yet confirmed. But there is a trend in the European Union and the United States to be replaced by dipropylene glycol dimethyl ether, a so-called "green solvent".

　　Solubility: Can be miscible with water, alcohols, ethers, esters, ketones, halogenated hydrocarbons, and aromatic hydrocarbons. Relatively stable in neutral media Can dissolve most polymers

　　Usage: Widely used in the refining of advanced lubricants, synthesis of polymers, insulation materials, pesticides, pigments, and cleaning agents. This solvent is a good dispersant for pigments (coatings) and can be applied to water dispersible coatings as well as solvent based coatings.

　　Waste liquid environmental treatment: Used and dirty methyl pyrrolidone can be recycled and reused through a solvent recovery machine and a vacuum pressure reduction system. Due to its high boiling point, direct recovery method cannot be used. Vacuum depressurization can reduce the heating temperature of recovery, ensure the quality of recovery, and improve the safety factor of recovery
