摘要
以甲苯为溶剂，二甲基二氯硅烷经过氨解反应得到八甲基环四硅氮烷．反应原料浓度经过优化，确定最佳浓度为2．07mol／L，最佳温度为15～18℃．后处理用氨水溶解副产物氯化铵，产品收率可达59％，并经IR表征结构、
Octamethylcyclotetrasilazane was synthesized from dimethyldichlorosilane and ammonia, IR was employed to characterized the structure of the product. The factors affecting the yield were investigated. The results showed that toluene as solvent, concentration of dimethyldichlorosilane：2.07 mol/L, reaction temperature： 15- 18 ℃, During post-treatment the by-product ammonium chloride was dissolved with agueous ammonia, The yield is above 59 %.
