- 中文摘要： 本研究探討與丙烯於不同矽／鋁比之絲光沸石上的異丙基化反應，反應係於 300℃,7kg/cm/sup 2/, 1h/sup -1/之空間流速下於固定床反應氣進行反應，丙烯與之進料莫耳比為6。不論矽／鋁比為何，絲光沸石均顯現出良好的2，6-形狀選擇性，的轉化率隨沸石矽／鋁比之增加而降低，2，6-與2，7-二異丙基之選擇率隨矽／鋁比增加而增加，2，6-二異丙基於二異丙基之選擇率與2，6-／2，7-異丙基之比均高於熱力學平衡值，二者均隨矽／比增加而增加。沸石之形狀選擇性隨著沸石的矽／鋁比與反應時間增加而顯著。
- 英文摘要： Isopropylation of naphthalene with propylene was carried out over mordenite zeolites with various Si/Al rations in the range of 23 and 112. The reaction was carried out in a fixed-bed reactor at 300. degree.C, 7kg/cm/sup 2/, WHSV=1h/sup -1/, and the molar ratio of propylene to naphthalene of 6. All mordenite zeolites exhibited significant shape selective properties. The naphthalene conversion decreased with an increase in the Si/Al ratio of the zeolite. Also, the selectivity of 2,6- and 2,7-diiosopropylnaphthalene (DIPN) in total DIPN increased with an increase in the Si/Al ratio. The compositions of 2,6-DIPN in total DIPN and the ratios of 2,6-/2,7 isomers for all zeolites are far above equilibrium values. Both of them increased with an increase in the Si/Al ratios. The shape selective properties would become more significant with an increase in the Si/Al ratio and the reaction time on stream.
