a-pyrrolidone

Property: 
A- pyrroidone is a colorless liquid. Its solidifying point 25.6° C, flash point 129.4° C, boiling point 245° C, which is solube with water, with short chain alcohol, with short chain ether, with chloroform and with benzene...
Usage: 
A- pyrroidone is a colorless high boiling point polar solvent and is also an organic synthetic intermediate product. As the solvnets we can use it to produce synthetic resin, pesticidde, polyvalent alcohol, printing inks and iodine, and as the raw materials, to produce polyvinylpyrrolidone, polyamide-4 fiber and piracetam, etc.
