| 摘 要： | 以聚苯胺PAn和自制离子液体[Hnmp]HSO4为原料,制备了[Hnmp]HSO4掺杂率为14.2%(质量分数)的催化剂PAn-[Hnmp]HSO4。以PAn-[Hnmp]HSO4为催化剂,水杨酸和异戊醇为原料合成了水杨酸异戊酯,考察了PAn-[Hnmp]HSO4的催化活性,通过正交试验探讨各因素对反应的影响。结果表明,在n(水杨酸)∶n(异戊醇)=1∶6,催化剂用量为反应物料总质量的6%,回流反应时间为3 h,带水剂环己烷用量为反应物总质量40%的较佳条件下,产品收率达93.52%,纯度经气相色谱分析大于99.0%。催化剂重复使用7次后,产品收率仍大于90.0%。

| Abstract: | Isoamyl salicylate was synthesized from salicylic acid and isoamyl alcohol with ionic liquid HSO4 doped polyaniline(PAn-HSO4) as catalyst.The catalyst was prepared from polyaniline and ionic liquidHSO4.Doping ratio(mass fraction) of the ionic liquid is 14.2%.Factors that influencing the product yield were investigated and optimum reaction conditions were obtained by orthogonal experiment.Results showed that under optimal conditions:n(salicylic acid)∶ n(isoamyl alcohol)=1∶ 6;dosage of the catalyst PAn-HSO4 6%(mass);dosage of water stripping agent cyclohexane 40%;and reaction time 3 h;yield and purity of isoamyl salkylate achieves 93.52% and 99.0% respectively.After the catalyst was reused for 7 times,yield of isoamyl salicylate is still higher than 90.0%. |
