摘要:
使用浸渍法将复盐NaAICl。负载在ZSM-5表面,对比使用不同硅铝比的ZSM-5分子筛作为载体,同时变化温度,综合研究不同催化剂对歧化生成二甲基二氯硅烷的影响.通过X射线衍射仪（XRD).气相色谱仪（GC)、电子扫描电镜(SEM)、比表面测试(BET’)、 NH,吸附–脱附(NH,-TPD)等对其进行了表征.结果表明:低温时反应为表面控制,高温时为活化控制.当温度为373K,负载比例为4% ,硅铝比为38时,催化剂活性达到最佳,产率为57.9% .
Abstract:
ZSM-5 zeolite with different Si/ Al ratios was selected as catalyst carrier and the salt of the NaAICl,as the surface load.The catalytic performance with different Si/Al ratios at different temperatures was com-pared to investigate the effects of Si/ Al ratio. Commonly used,the catalysts were characterized by X-ray dif-fraction (XRD),GC,scanning electron microscope ( SEM),BET and NH, -TPD and so on. The catalystwhich Si/ Al ratio was 38 had the greatest acidity and was the most active one. The results showed that the cat-alytic activity depended on the surface area at low temperature,while at high temperature depended on the ac-tivation sites.When Si/ Al ratio was 38,at 373 K,Cat-4% showed the best catalytic effect,of which yield ofdichlorodimethylsilane was 57. 9 % .
