Using solid superacid TiO_2/SO_4~(2-) as catalyst in the synthesis of isoamyl acetate, Optimal conditions were studied. Tranaformation rate up to 95.3%. 研究了固体超强酸TiO_2/SO_4~(2-)活化温度与催化活性之间的关系;探索了使用本文方法制备的固体超强酸TiO_2/SO_4~(2-)催化制备乙酸异戊酯的最佳反应条件,且获得了在最佳条件下乙酸转化率为95.3%的结果。 The analysis of reaction system,in which 1,2,3,5-tetramethylbenzene was catalytically converted to 1,2,4,5-tetramethylbenzene, was investigated on the glass capillary column covered with polyethylene glycol 20M by gas chromatography.Quantitative determinatlon was carried out by using the corrected area normalization,The variation coefficience of relative correction factors were less than 2 %. The relative errors of the component were less than 3%. 在聚乙二醇-20M的毛细管柱上建立了1,2,3,5-四甲苯催化制备1,2,4,5-四甲苯反应体系的气相色谱分析方法。采取校正面积归一法定量,测定相对校正因子的变异系数小于2%,组分含量分析的相对误差小于3%。 The esterification reaction between isobutyric acid and benzyl alchol catalyzed by FeCl3 is reported in this paper. The conditions for preparing benzyl isobutrate catelyzed by various chlorides are investigated. It is proved that FeCl3 is the best catalyst. 本文研究了FeCl3催化制备异丁酸和苄醇的酯化反应,探讨了多种氨化物催化制备异丁酸苄酯的条件,其实验结果表明,FeCl3催化活性最好.
