Is NMP harmful?

Is NMP harmful?

The European Chemicals Agency classifies NMP as a “Substance of Very High Concern” because of its toxicity to reproduction based on developmental toxicity.

What is N methyl pyrrolidone used for?

N-Methylpyrrolidone (NMP) is a solvent used in a variety of industries and applications, such as paint and coating removal, petrochemical processing, engineering plastics coatings, agricultural chemicals, electronic cleaning and industrial/domestic cleaning.

Is NMP explosive?

Hazard Class: 3 (Flammable) 1-Methyl-2-Pyrrolidone is a COMBUSTIBLE LIQUID. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. POISONOUS GASES ARE PRODUCED IN FIRE, including Nitrogen Oxides. Use water spray to keep fire-exposed containers cool.

Is N methyl pyrrolidone a VOC?

NMP is considered a volatile organic compound (VOC) and is a California Prop 65 substance.

How do you make methyl 2 pyrrolidone?

N-Methyl-2-pyrrolidone (NMP) is prepared by preparing a mixture comprising monomethylamine, dimethylamine and trimethylamine and ammonia in a first process step by reacting ammonia with methanol at elevated temperature in the presence of a catalyst, separating 10 off the ammonia, reacting the mixture comprising the …

Which hazard does not apply to methanol?

Possible hazardous reactions:None under normal processing. Conditions to avoid:Excess heat, Incompatible Materials, flames, or sparks. Incompatible materials: Oxidizing agents, reducing agents, alkali metals, acids, sodium, potassium, metals as powders, acid chlorides, acid anhydrides, powdered magnesium, and aluminum.

Does NMP evaporate?

First, NMP is a very slow evaporating solvent. It has a boiling point of 202°C. A thin film of NMP requires over 15,000 s for 90% evaporation at room temperature. The most effective fast-evaporating solvent for these resins is DMF, but that solvent has serious safety issues.

Is NMP soluble in water?

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.

Is NMP a hap?

NMP is not listed as a Hazardous Air Pollutant (HAP) under Section 112 of the Clean Air Act. NMP is not listed as a Hazardous Substance, Priority Pollutant or Toxic Pollutant under the Clean Water Act. NMP is listed under TSCA and is subject to reporting in the Toxics Release Inventory.

Is N methyl 2 pyrrolidone corrosive?

It mixes with water in all proportions. It has a high flash point compared to similar solvents. The boiling point is high, the freezing point is low, and handling is easy. It is chemically and thermally stable, and not corrosive.
