Up to the present, the manufacture process of acetic acid is still the method of acetaldehydeoxidation in this factory. The rectification technology was a twin tower flowsheet.
With the implementation of these measures, the effective results are obtained apparently, explosion accident of acetaldehydeoxidation tower is prevented, and yield of acetate is raised.
实施后有效地防止了乙醛氧化塔的爆炸事故，并提高了醋酸收率，取得了良好的效果。

It was formerly derived by fermentation of carbohydrates but is now made synthetically by aldol condensation of acetaldehyde or by oxidation of petroleum gases.
