Introduction: N-Methylpyrrolidone (NMP) is a versatile chemical solvent that is used in a variety of
industrial and manufacturing applications. It is a clear, colourless liquid which can be
miscible with water in any proportion, soluble in ether, acetone and various organic solvents
such as esters, halogenated hydrocarbons, aromatic hydrocarbons, and almost completely
mixed with all solvents. It can dissolve polar and non-polar compounds. an ideal solvent for removal of paint and
coatings, electronics cleaning, and the manufacturing of pharmaceuticals and
agrochemicals. So it is widely used in below mentioned fields:
1) Electronics and Battery Manufacturing : Electronic parts cleaning/ Semiconductor parts cleaning/ Solvent for lithium battery
manufacturing/ Semiconductor photo-resist thinner/ Color filter photo-resist thinner;
2) Agriculture:
used in the formulation of certain pesticides and fertilizers, enhancing their effectiveness
and stability. These applications highlight NMP's versatility as a solvent across various sectors. Its ability
to dissolve different materials, coupled with its thermal stability and low toxicity, makes it
an indispensable component in many industrial processes. 3)Paint and Coating Industry:
NMP is a preferred solvent in paint and coating strippers due to its ability to dissolve a wide
range of polymers and resins effectively. Its use in this sector underscores its versatility and
efficiency.
4) Pharmaceuticals
In the pharmaceutical industry, NMP is used for the extraction, purification, and
crystallization of various drug ingredients. Its effectiveness as a solvent ensures high purity
and quality in pharmaceutical products. 5) Petrochemical:
