| 摘 要： | 研究以过磷酸为催化剂催化甲酸甲酯与三聚甲醛偶联合成乙醇酸甲酯。通过对以过磷酸、浓硫酸及过磷酸与浓硫酸混合酸为催化剂时反应现象、乙醇酸甲酯及甲氧基乙酸甲酯总产率等的对比研究,发现过磷酸具有良好的催化性,产品产率高达59 06%,催化效果较常用的浓硫酸强,但选择性不如浓硫酸。 |

Synthesis of Methyl Glycolate from Formaldehyde and Methyl Formate with Superphosphoric Acid as CatalystⅠ. Comparison of the Catalytic Capacity |
|
| Abstract: | The synthesis of methyl glycolate by methyl formate coupled with thrioxane with superphosphoric acid as catalyst is researched experimentally Through seeing about the reactions catalyzed, respectively, by superphosphoric acid, sulfuric acid and mixed acid and their yields of methyl glycolate and methyl methoxyglycolate, it was found that superphosphoric acid was an better new catalyst with a best yield of 5906% Superphosphoric acid is better than sulfuric acid in activity, but worse in seletivity |
| Keywords: | mehtyl glycotate methyl formate trioxane superphosphoric acid |
