Advances in vapor phase catalytic synthesis of pyrrolidine

The production technologies of pyrrolidine via vapor phase catalytic process are reviewed,which mainly involves amination reaction of tetrahydrofuran with ammonia,amination reaction of butane-1,4-diol with ammonia,ω,ω'-aminalbutanol cyclization method,hydrogen denitrogenation method,as well as electrochemical method etc.The characteristics of amination reaction both reduction catalysis and acid catalysis are presented and the effects of supports and promoters of the catalysts on the catalytic performance are also discussed.It is point out that the future development should be mainly concentrated on more efficient and also more selective catalysts and environmentally friendly processes.
