The reasons for the failure of the methanol product oxidation test are: 1. Incomplete removal of light components such as ethers from the pre-tower； 2. The low amount of base added in advance results in incomplete decomposition of the readily decomposable carbonyl compounds in crude methanol ； 3. The content of organic Reorganization components in crude methanol is too high ； 4. In a pressurized or atmospheric pressure column, the reflux ratio is set too low, causing the heavier components in the column to move upward and to emerge with the product at the top of the column ； 5. Excessive heating steam volume in the pressure column reboiler causes mist entrainment or flooding of the column.
