摘 要: | 以天然亚茴香基丙酮为原料,Lewis酸为催化剂,环己烷为氢源,研究了天然茴香基丙酮的合成工艺,并探讨反应机理和反应的选择性。对不同Lewis酸催化剂与溶剂进行筛选,确定Al Cl3为催化剂,CH2Cl2为溶剂,采用正交试验方法对茴香基丙酮合成工艺进行优化,得到最佳工艺条件。在反应温度35℃,反应时间4 h,n(Al Cl3)∶n(亚茴香基丙酮)4∶1,n(环己烷)∶n(亚茴香基丙酮)4∶1的条件下反应稳定性较好,产物得率达95.1%。采用IR、GC-MS和1H NMR等分析技术对合成所得产物进行了表征。

Synthesis and Process Optimization of Hydrogenation of Natural Anisyl Acetone Using Lewis Acid as Catalysts |
| |
Abstract: | Synthesis of natural anisyl acetone was investigated by using natural base to Asia anisyl acetone as raw material , Lewis acid as catalyst , cyclohexane as a source of hydrogen .Different Lewis acid catalysts with different solvents were screened .The optimum synthesis conditions were determined based on the orthogonal test results as follows :the reaction temperature is 35 ℃, n(AlCl3)∶n(asia anisyl acetone)4∶1 and n(cyclohexane)∶n(asia anisyl acetone)4∶1.Three experiments were carried out under these conditions .A good stability was obtained .The yield of the product 4-( 4-methoxyphenyl )-2-butanone could reach 95%.Reaction mechanism and selective of product were discussed .The structure of the product was identified by FT-IR, GC-MS and 1H NMR spectrum. |
