9.(1)蒸馏烧瓶　除去乙烯中的SO2、CO2和乙醇蒸气
(2)a　水浴加热　停止加热，冷却至室温后补加沸石，继续实验　(3)6[(C2H5)2PO2]Na+Al2(SO4)32[(C2H5)2PO2]3Al↓+3Na2SO4　(4)充分洗去产品上粘附的Al2(SO4)3、Na2SO4等可溶性物质　加快过滤速率，利于产品干燥　(5)95.0%(或0.95)
解析　(1)新制的乙烯中混有SO2、CO2、乙醇蒸气和水蒸气，水蒸气不影响实验，故试剂X可选用NaOH溶液，用于除去乙烯中的SO2、CO2和乙醇蒸气。
(2)由信息知，NaH2PO2·H2O有较强的还原性，为防止NaH2PO2被氧化，应先加热仪器a，用生成的乙烯排尽装置中空气。
(5)6.36 g NaH2PO2·H2O的物质的量为0.06 mol，由反应原理得关系式：3NaH2PO2·H2O~3[(C2H5)2PO2]Na~[(C2H5)2PO2]3Al，则产品的理论产量为0.02 mol，其质量为7.80 g，则本实验中产品的产率为×100%=95.0%。
10.(1)+123 kJ·mol-1　升高温度或降低压强　(2)①B　②A　二氧化碳作为稀释气降低分压并消耗氢气，促进乙苯脱氢反应平衡正向移动　(3)N　1.52
解析　(1)利用表中数据可得，ΔH1=413 kJ·mol-1×2+348 kJ·mol-1-615 kJ·mol-1-436 kJ·mol-1=+123 kJ·mol-1，反应Ⅰ和Ⅲ的正反应为体积增大的吸热反应，为提高的平衡转化率，可采取的措施为升高温度或降低压强。
