摘　　要：一异丙基萘、二异丙基萘及三异丙基萘的热稳定性好，可再生，能长期在３３０～３５０℃的高温下运行，流动点低，使用方便，无腐蚀和不愉快气味，是一种优良的导热油。用天然硅铝酸催化丙烯对禁烷基化，在催化剂用量为８％、丙烯与萘的物质的量比为２：１及反应温度１５０℃、反应时间６ｈ的条件下，一、二及三异丙基萘的收率分别为５７．９％、２３．１％和１２．２％。onoisopropylnaphthalene, diisopropylnaphthalene and triisopropylnaphthalene are ideal heat conducting oils, with good heat stabilities and low flow points, capable of being regenerated and operated at a high temperature of 330～350℃, free from erosion and unpleasant odors.The products were obtained via alkylation of naphthalene by propylene using natural silicoaluminic acid-based catalyst. The yield of mono-, di-and tri-isopropylnaphthalene was 57. 9%, 23. l% and 12. 2%, respectively, when the dosage of catalyst was 8%, the molar ratio of propylene to naphthalene 2:1, the temperature 150℃, and reaction time 6 hours.
