中文摘要	利用形貌表征、元素组成分析、热重分析、拉曼光谱表征等方法,对氯苯和甲基二氯硅烷气相缩合法合成甲基苯基二氯硅烷(MPDS)过程的积炭特性进行了研究.结果表明,MPDS合成过程中的积炭石墨化程度高,且均为不可溶解炭.氢/碳摩尔比为0.35～1.74;在氧气气氛中积炭主要的失重温度区间为650～1100 K,烧炭过程为一级反应,表观活化能为117 k J/mol;氯苯对积炭的贡献大于甲基二氯硅烷,相同条件下氯苯的积炭量是甲基二氯硅烷的3倍.可适当降低氯苯预热温度以减少积炭.; Coke deposition features in methylphenyldichlorosilane(MPDS) synthesis by gas phase condensation from chlorobenzene(Ph Cl) and methyldichlorosilane(MH) were studied with morphology characterization,element analysis,thermogravimetry and Raman spectroscopy.The deposited coke formed in MPDS synthesis had high graphitization degree,and was insoluble coke.The molar ratio of hydrogen to carbon was 0.35～1.74.Thermogravimetric analysis was carried out in the oxygen atmosphere,the main weight loss temperature range was 650～1100 K.The coke burning process was first order reaction with the apparent activation energy of 117 k J/mol.The contribution of Ph Cl to the deposited coke was more significant than that of MH,and the amount of deposited coke formed from Ph Cl was 3 times as much as that formed from MH.Therefore the preheating temperature of chlorobenzene should be decreased to reduce the deposited coke.
