Abstract: 
Досліджено процес одержання метилгліколату з метанольного розчину гліоксалю на твердих оснóвних каталізаторах на основі змішаних оксидів алюмінію, цирконію та магнію. Cелективність утворення метилгліколату зростає зі збільшенням основності каталізатора. Найбільш селективний співосаджений MgO-ZrO2 каталізатор забезпечує практично 100 % вихід метилгліколату. На MgO-ZrO2/Al2O3 спостерігається 95%-й вихід метилгліколату з утворенням гліоксальдиметилацеталю як побічного продукту. Метилгліколат з високим виходом 93 % можна отримувати в проточному режимі, що може представляти практичний інтерес.
