纳米固体超强酸SO42-/TiO2催化合成富马酸二甲酯
Study on Catalytic Synthesis of Dimethyl Fumarate by Nanosolid Superacid SO42-/TiO2
【摘要】 采用溶胶-凝胶法制备了纳米固体超强酸SO24-/TiO2催化剂,主要研究了它的制备条件及作为催化剂在合成富马酸二甲酯中的反应条件,并用正交实验法确定了合成反应的最佳条件。实验结果表明纳米固体超强酸SO24-/TiO2具有很强的催化活性。
【Abstract】 The nanosolid superacid catalyst SO2-4/TiO2 was prepared by sol-gel method.The preparation conditions of nanosolid superacid and synthesis conditions of dimethyl fumarate using it as catalyst were emphatically investigated.The optimum synthesis condition was determined by orthogonal experiment.The experimental results indicates that SO2-4/TiO2 nanosolid superacid has high catalytic activity.
