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％。 Isopropyl Naphthalene, Diisopropyl Naphthalene and Triisopropyl Naphthalene have good thermal stability and can be regenerated. They can run at high temperature of 330 ~ 350 ℃ for a long time, have low pour point, easy to use, non-corrosive and unpleasant smell , Is a good heat-conducting oil. Using natural aluminosilicate to catalyze the ban on alkylation of propene, under the condition of the amount of catalyst is 8%, the molar ratio of propylene and naphthalene is 2: 1, the reaction temperature is 150 ℃ and the reaction time is 6h, The yield of isopropylnaphthalene was 57.9%, 23.1% and 12.2%, respectively.
