摘要
以二氧化硅负载磷钨杂多酸为催化剂,以长链α-烯烃为烷基化试剂和萘发生烷基化反应,考察了不同烯烃、不同反应条件对产品收率和产品质量的影响。研究结果表明,采用1-十六烯作为烷基化试剂,在催化剂加入量(w)为4%、反应温度130℃、烯烃与萘摩尔比为1.35、反应时间50 min的条件下,产品收率为88.2%,DSC(O2)氧化分解温度为225.3℃,粘度指数为104,倾点为-27℃。
A new synthetic technique for preparing long-chain alkylated naphthalenes was developed using naphthalene and long-chain linear alpha-olefins as raw materials and heteropoly acid （silica-supported 12-phosphotungstic acid）as catalyst. The influences of various olefins and reaction conditions on the product yield and properties were studied. It was found that under the optimum reaction conditions of using cetene as alkylation agent, a catalyst dosage of 4%, a cetene to naphthalene molar ratio of 1.35,a reaction temperature of 130 ℃ and a reaction time of 50 min, the product yield was 88.2%. The obtained product had a viscosity index of 104, a pour point of -27℃and with good oxidation stability,its oxidation decomposition temperature by DSC（O2）test was 225.3℃.
