Uses:
As a high-selective polar solvent and nitrogen heterocycle compound, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and high selectivity.

N-Methyl-pyrrolidone(electronic grade) is mainly used in such fields as:
(1) As solvent of poly(1,1-difluoro-Ethene); or electrode's accessory material of lithium ion battery.
(2)As remover liquid of photoresist; in the production of LCD materials;
(3)As solvent in pharmacy;
(4)Cleaning of precision instruments and circuit board.

1-Methyl-2-pyrrolidinone(industrial grade) is mainly used in such fields as:
(1)Extraction and recycling of organic raw materials in petrochemical industry
(2)Refining of lubricating oils
(3)As solvent of polymers and in polymerization.
(4) As solvent of resin processing in the manufacture of coatings, lacquer for floor, varnish, compound coating filming, enameled wire of IC, fiber fabrics and adhesives, etc.
(5) As industrial-use detergents in the cleaning of chemical equipments, stem, adhesive material and coatings etc.
(6) As solvent and dispersant in the production of pesticides and pigments.

Storage and transportation:
