甲酸甲酯与三聚甲醛合成乙醇酸甲酯 Ⅲ.羰化反应机理的初步探索

Synthesis of methyl glycolate by coupling methyl formate with trioxane Ⅲ.Exploration of carbonyl reaction mechanism

提出并初步证实了甲酸甲酯与三聚甲醛合成乙醇酸甲酯反应中的羰化反应机理，具体为：（１）甲酸甲酯分解产生ＣＯ和甲醇；（２）甲醛羰化、甲缩醛羰化形成乙醇酸甲酯和甲氧基乙酸甲酯；（３）产物间部分聚合反应。

The reaction mechanism is proposed and vertified for synthesis of methyl glycolate via coupling methyl formate with trioxane, which involves decomposition of methyl formate into carbon monoxide and methanol, trioxane carbonylation and methylal carbonylation to give methyl glycolate and methyl methoxyacetate, and polymerization of part of the products.
