结果表明,以自制新鲜氢氧化铝为铝源,以硅溶胶为硅源,以钛酸丁酯为钛源,以氨水为沉淀剂,在pH=6.2,c(Al3+)=0.64 mol/L(V(H2O)=200 ml)的条件下,采用通常的沉淀方法可制备出性能优良的催化剂. 催化剂的酸性是影响其催化性能的主要因素,主产物选择性与酸强度有关,酸强度高的催化剂具有较低的主产物选择性;催化剂的活性与其孔径及表面酸量有关;催化剂中的B酸中心是反应可能的活性中心.","authors":[{"authorName":"<span style=\"color:red\">李</span><span style=\"color:red\">雪</span><span
