摘要

用甲苯作溶剂，二苯基二氯硅烷与氨气反应得到六苯基环三硅氮烷。通过正交实验，获得适宜的工艺条件：二苯基二氯硅烷浓度0.96mol/L，反应温度111-112℃，氨气流量0.02m3/h，后处理用氨水溶解副产物氯化铵，六苯基环三硅氮烷收率达到91.1%，并经IR表征结构。

Abstract

Hexaphenyl cyclotrisilazane was synthesized from diphenyl dichlorosilane and ammonia with toluene as solventThe effects of input material concentration

reaction temperature

ammonia flow rate and separation method on product yield were investigatedThe structure of hexaphenyl cyclotrisilazane was characterized with FTIR and XRDIt was found that when diphenyl dichlorosilane concentration was 096 mol·L-1

reaction temperature was 111—112℃

NH3 flow rate was 002 m3·h-1

the yield of hexaphenyl cyclotrisilazane could reach 911%Using ammonia water was better than hot filtration to weed out ammonium chloride at the period of product separationIt enhanced separation efficiency and simplified the processAt the same time it also decreased pollution to the environment by reducing volatile matter of toluene.
