乙二醛生产工艺评述

Processes review on production of glyoxal

介绍了乙二醛的两种生产工艺 ,即乙二醇气相催化氧化法与乙醛硝酸氧化法 ,并对两种工艺进行了比较与评价。认为国内应大力开发乙醛硝酸氧化法生产乙二醛的工艺 ,目前的迫切任务是提高产量与产品质量。

The two processes of producing glyoxal by catalytic oxidation of ethandiol in gas phase, and oxidizing acetaldehyde with nitric acid were introduced and compared. It was thought that the new process for producing glyoxal by oxidizing acetaldehyde with nitric acid should be developed inland, and the urgent task was increasing yield and quality.
