γ- butyrolactone with methylamine to form N- methyl- pyrrolidone (NMP). NMP is a good solvent , can be selectively separated aromatics , its extraction selectivity ; no corrosion, good chemical stability and thermal stability ; dissolving capacity for aromatics , are widely used in petroleum chemical industry , extraction of acetylene , butadiene , aromatics , gas desulfurization, advanced lubricants. N- methylpyrrolidone is used as the resin and the polymerization solvent recovery PVC , polyamides, polyimides and varnish solvent extraction solvent. It is good industrial cleaning agents , used for ultrasonic cleaning of precision mechanical and optical instruments . γ- butyrolactone with ammonia and acetylene can generate N- vinylpyrrolidone, the pharmaceutical industry, cosmetics ( mousse styling agent ) , an important raw material adhesives . N- vinyl pyrrolidone in the catalyst into a polymerization polyvinylpyrrolidone (PVP). PVP can be used in medicine , and some drugs such as iodine complexing agent ; stationery aspects may also be used , such as glue ; also used in cosmetics, such as hair finishing agents , flavoring agents , skin care agents, bath agents, dentifrices ; in terms of fabrics and dyes used as adhesives ; clarifying agent for beverages , can improve the clarity of wine , vinegar , tea, fruit juices , and can stabilize the color , flavor and other improvements .
