    NMP is a 5-member-ring compound containing nitrogen.  It has a wide range of uses due to the following excellent characteristics.

    ---It is highly polar and miscible with most organic solvents (alcohols, ethers, ketones, aromatic

         hydrocarbons, chlorinated hydrocarbons, etc.).  Organic and inorganic substances are highly 

         soluble in it.

    ---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.

    Applications

    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.

    Electronics:
    NMP is used as photoresist stripper, for defluxing, degreasing and cleaning.
    NMP is a solvent for the production of FCCL, polyamide/polyimide wire enamels, epoxy and polyurethane coatings.

    Pharmaceuticals:
    NMP can be used as solvent, extraction medium.

    Industrial and household cleaning:
    NMP is used for paint stripping, in graffiti removers, oven cleaners, in automotive and industrial cleaner formulations.

    Agrochemicals:
    NMP can be used as solvent during synthesis or as a formulation agent.
