Trade name: |
N-methyl-pyrrolidone |
Formular: |
C5H9NO |
Structure: |
 |
Properties: |
N-methyl-pyrrolidone,which is a liquid with little ammonia odor,can mixed with almost all solvents such as ethyl alcehol,acetaldehyde,ketonc,aromatic hydrocarbons and chlorohydros carbons etc.Its boiling 204°C and flash point 95°C. |
Usage: |
NMP which is a polar non proton transfer Solvent possesses little toxicity,high boiling point,poweful solvency,good selectivity and stability properties.The product is widely applied to aromatic hydrocarbons extracting,acetylene,and diolefine purification.It can be also used as polymer solvents and pulymerization process medium,such as polyamides,polyimides amd polyphenyl thioether(pps),etc.which are called engineering plastics.Besides these,it can be used as aromatic fibre,pesticide,insulate pigment and detergent,etc. |
