在超声波作用和无溶剂条件下,对氯苯甲醛与硝基甲烷发生缩合反应得到了β-硝基烯。最佳反应条件为反应时间2h,物料配比为n(对氯苯甲醛)∶n(硝基甲烷)∶n(氢氧化钠)=1∶40∶2.5。在此最佳反应条件下,β-硝基烯产率为80%。
Under ultrasonic and solvent-free conditions, p-nitrophene was obtained through condensation reaction of p-chlorobenzaldehyde and nitromethane. The best reaction conditions for the reaction time 2h, the material ratio of n (p - chlorobenzaldehyde): n (nitromethane): n (sodium hydroxide) = 1:40: 2.5. Under this optimal reaction conditions, the yield of β-nitrene was 80%.
