高温高压合成N-甲基-2-吡咯烷酮工艺研究

Synthesis of N-methyl-2-pyrrolidone at High Temperature and High Pressure

在压力3.0MPa,温度230℃、NMA:GBL=1.2～1.35mol的条件下,采用三釜串并联连续反应生成N-甲基-2-吡咯烷酮,操作简单、平稳,产率高于单釜反应。

Under 3.0 MPa and at 200-240 C,NMA：GBL= 1.2-1.35 （mol）, the three-reactor series and parallel for the reaction of N-methyl-2-pyrrolidone. the operation is simple and stable, the yield is better single reactor.
