摘要
硫酸氢钠能够代替硫酸作为成醚催化剂。以乙二醇为原料 ,一水硫酸氢钠为脱水催化剂 ,合成了 1,4-二氧六环。研究结果表明 ,硫酸氢钠的催化活性良好 ;当 0 .4mol乙二醇 ,0 .0 2mol硫酸氢钠 ,反应 2h ,产品收率达 6 7%。此法具有操作方便 。
The synthesis of 1,4-dioxane employing the ethanediol as raw material and sodium bisulfate monohydrate as catalyst was discussed.The results showed that the yield was 67% under 0.4 mol ethanediol,0.02 mol sodium bisulfate,reaction time is 2h.this method has the advantages of simple operation and mild reaction condition.
