摘要/Abstract

摘要： 以三异丁烯和苯酚为原料,采用阳离子交换树脂Amberlyst15作催化剂,合成支链十二烷基苯酚,考察了温度、时间、催化剂用量和酚烯摩尔比等反应条件对烷基化反应的影响。通过正交实验法对工艺条件进行了优化。结果表明,当烷基化时间8h,酚烯摩尔比为6,树脂质量分数为20%,反应温度为45℃时,得到的十二烷基酚收率为47.1%,辛基酚收率为43.1%,总体烷基酚收率达到90.2%,支链十二烷基苯酚的收率达50%左右。

Abstract:

Using cation exchange resins Amberlyst 15 as catalyst, triisobutene and phenol as raw materials, synthesized branched-chain dodecylphenol. The effects of temperature, time, the amount of catalyst and mole ratio of phenol and olefin on the alkylation were researched. The impacts conditions were optimized by orthogonal experiment.The results show that alkylation of time is 8 h; mole ratio of phenol and olefin is 6; mass fraction of catalyst is 20% ; reaction temperature is 45 ℃, the maximum dodecylphenol yield (47.1%) could be obtained so that the utilization of triisobutene could reach 90.2%, the yield of branched-chain dodecylphenol could up to 50%.
