摘要:      采用均匀设计试验探讨固体超强酸SO2 -4 /SnO2 制备条件, 并将该催化剂用于油酸正丁酯的合成, 结合逐步回归分析和单因素多水平实验对分析结果进行讨论和验证, 得到了该催化剂制备的最佳条件。SO2 -4 /SnO2固体超强酸催化剂的最佳制备条件为:浸渍液浓度为1.5 mo l/ L、浸泡时间0 .5 h、焙烧温度400 ℃、焙烧时间1 h , 在最佳条件下, 油酸正丁酯的酯收率高达99 .22 %, 催化剂在连续使用5 次后, 酯收率为94 .03%, 无明显失活, 稳定性好。

Abstract:

        The preparation conditions of solid superacid SO2 -4 /SnO2 were investigated by uniform design , and the solid superacid was used as catalyst in the synthesis of n-butyl oleate .The optimum conditions of preparation of SO2 -4 /SnO2 were determined by regression analysis and single factor more level analysis , i.e ., the concentration of impregnating solution is 3 .0mol/ L , impregnating time is 0.5 h , calcinating temperature is 400 ℃, and calcinating time is 1h .Under optimum conditions, the yield of esterification is up to 99 .22%.At the same time , the catalyst was used repeatedly for 5 times without any apparent loss of the conversion and the yields of esterification is 94 .03%.

Key words: Uniform design,    , Solid superacid,    , Preparation,    , Esterifiaction
