2-Pyrrolidone is an organic synthesis intermediate in the pharmaceutical industry, precursor of N-vinylpyrrolidone.
The product is used as a plasticizer and a setting agent for acrylic emulsions and acrylic/styrene copolymers used in floor polishes.
2-Pyrrolidone reacts with halogens at 0°C to give N-halogeno-2-pyrrolidones.
In a strongly alkaline medium, 2-Pyrrolidone hydrolyses to a salt of aminobutyric acid. 2-Pyrrolidone adds to acrylonitrile to give cyanoethylpyrrolidone and, on reaction with formaldehyde, it gives N methylolpyrrolidone.
2-Pyrrolidone is hygroscopic and must be stored in a dry place, preferably in its original packaging.
The product solidifies below 25°C, if that happens, it must be slowly melted by placing it in a warm room at a temperature of 40°C or by using a heating jacket to that temperature. Higher temperatures are likely to make the product turn yellow.
Avoid contact with skin and eyes, and take all normal precautions for handling chemicals. Gloves and protective goggles are recommended.
In the event of accidental spillage, soak up or contain the spilt liquid with sand or earth and dispose of this waste in accordance with current legislation. Wash the area of spillage with water, which should be handled as chemical waste.
