| 摘要: |
| 在微型高压反应釜中（１２０ｍＬ），研究了通过自制的固体超强酸（ＳＯ２＾４／ＺｒＯ２）协同浓Ｈ２ＳＯ４催化三甲醛和甲酸甲酯偶联制备乙醇酸甲酯的反应。固体超强酸（ＳＯ４＾２－／ＺｒＯ２）的引入，大大地降低了浓Ｈ２ＳＯ４催化该偶联反应的的用量。研究了酸催化剂中质子的作用并初步探讨了偶联反应的机理，认为该偶联反应分三个步骤完成，第一步是酸催化甲酸甲酯的分解产生ＣＯ和ＣＨ３ＯＨ；第二步是甲醛的羰化形成乙醇酸 |

| Abstract: |
| The solid sopracid samples (SO42-/ZrO2) were prepared and their synergtic effect with conentrated sulfuric acid on the synthesis reactions of methyl glycolate (MG) were investigated from the couplings of methyl formate and trioxan, in a microform high-pre |
