摘要
文中对国内外一些学者在醚化反应中所采用的各种催化剂进行了介绍及比较。目前普遍采用强酸性大孔阳离子交换树脂类型的催化剂生产MTBE,其异丁烯的转化率高,选择性好。但树脂催化剂的缺点是,一旦表面积炭而失活,因无法烧焦再生,使投资增加。因此,将酸性强、热稳定性好的沸石分子筛为催化剂用于醚化反应已成为一种趋势。文中对用于醚化反应的沸石分子筛催化剂的发展动态进行了评述,并对今后开发分子筛醚化催化剂的工作提出了一些建议。
The study and development of molecular sieve catalysts for the etherification of i -olefines with alcohols to produce alkylethers are summarized. Other types of catalysts for etherification are also discussed briefly. Suggestions for the further development of molecular sieve catalysts for etherification are also put forward.
