改性kl沸石催化合成碳酸二甲酯
DOI: 10.3969/j.issn.1671-7627.2015.02.023, PP. 121-124
Keywords: l型分子筛,碳酸二甲酯,非均相催化
Abstract:
采用固相研磨法制备koh负载于kl型分子筛的非均相催化剂koh/kl,用于催化碳酸丙烯酯和甲醇合成碳酸二甲酯反应,探索其在不同koh负载量、焙烧温度下对催化性能的影响;采用x线衍射仪(xrd)及n2吸附仪进行表征分析。结果表明:焙烧温度为400℃、koh负载量为30%的催化剂l型骨架结构未被破坏,活性组分很好地分散在孔道中;在反应温度为70℃,反应4h的条件下,碳酸丙烯酯转化率达到49.5%。
