preparation
Production of 2-pyrrolidon by hydrocyanc acid and acrylonitril Hydrocanic acid (HCN) reacts with acrylonitril (AN) to prepare 2-pyrrolidon,
The reaction process is:
1) The addition reaction of HCN and AN is catalyzed by triethylamin to generate succinonitrile. The reaction was carried out at atmospheric pressure and about 70°C, and the yield of succinonitrile was as high as 97%.
2) Partial hydrogenation reduction of succinonitrile to aminobutyronitrile, reaction Chemicalbook uses carrier nickel as hydrogenation catalyst, total pressure 14.0MPa, temperature 80~100ºC, using liquid ammoni as solvent, succinonitrile conversion rate is close to 100%, The selectivity of aminobutyronitrile is 85%.
3) γ-aminobutyronitrile hydrolysis and cyclization reaction generates 2-pyrrolidon. This reaction is carried out in a plug flow system at a temperature of 210 °C, and the nitrile conversion rate and product selectivity are both close to 100%.
