超声波辐射时间对固液相亲核取代反应的影响

The Effect of Supersonic Wave Radiation Time on Solid-Liquid Two Phase Necleophilie Substitution Reactions

研究了亲核试剂与不同结构卤代烃的取代反应中,超声波辐射时间对收率的影响。结果表明当反应一定时间后,某些反应收率开始下降。说明超声波辐射对该反应既有促进主反应的作用,又有加速逆反应的效果。因此,应根据不同反应,将辐射时间控制在一定范围之内。

The effect of supersonic wave rediation time on the yield of necleophilic seactions of come halides has been studied.The result shows that for some of the reactions the yield begin decrease after a period of time,supersonic wave may promate main reactions as well as adverse reactions.So the radiation time should be controlled according ro the different reactions.
