【摘要】 考察了焙烧温度、硫酸浓度对自制的γ-Al₂O₃负载纳米级SO₄^2-/TiO₂固体超强酸的酸强度、比表面积的影响;用不同条件下制得的γ-Al₂O₃负载纳米级SO₄^2-/TiO₂固体超强酸催化乙酸和正丁醇酯化反应,检测乙酸转化率;讨论了影响γ-Al₂O₃负载纳米级SO₄^2-/TiO₂固体超强酸催化活性的因素,为批量制备提供参考.更多还原

【Abstract】 Theγ-Al₂O₃ supported nano-sized SO₄^2-/TiO₂ solid super acid was prepared.The effect of sulphuric acid concentration and calcining temperature on acidity and specific surface area of theγ-Al₂O₃ supported nano-sized SO₄^2-/TiO₂ solid super acid was studied.The effect on catalytic activity of theγ-Al₂O₃ supported nano-sized SO₄^2-/TiO₂ for esterification of acetic and n-butanol was discussed,which can provide the reference for mass production.更多还原
