摘　　要：萘由于是固体且在常温下难溶于一般溶剂,所以它的异丙基化反应研究通常是一个棘手的问题。微型淤浆床提供了一种简单可行的方法。我们采用MP-01催化剂,研究了萘和丙烯的烷基化反应,得到了一系列数据。结果发现温度、反应时间、萘烯比甚至溶剂都会对反应产生影响,数据在文中加以罗列。在200℃经过70min,反应仍未达到平衡。为了尽量减少产物中的重组分,最佳的反应条件应该是温度250℃,压力2.5MPa,体积空速1 h-1,并且不使用溶剂,溶剂的存在会延长反应达到平衡的时间。The research of naphthalene alkylation is normally tough as its solid state and hard to dissolve in solvent at the room temperature. It gives a reliable method when naphthalene and propylene react under a micro-slurry bed reactor. In our study, on PM-01 catalyst we find that conditions such as temperature , reaction time, naphthalene /propylene ratio （n/p）,even solvent have effect to the product distribution at last. Data of different product distribution at different time are listed in this sheet. Under the temperature of 200℃, after the reaction time of 70 minutes, there is still no equilibrium. In order to get least heavy component from the product, the optimal reaction conditions may be 250℃,2.SMPa, GHSV =1 h-1and n/p =2：1. Solvent must not be available in the reaction, because it takes longer time to equilibrium.
