Brief summary: By-products of methanol synthesis and their impact on the quality of the resulting methanol. Side reactions in methanol synthesis produce substances such as formic acid, ethanol, paraffin, and diethyl ether. The main impacts on the quality of methanol products are as follows: 1. Side reactions during methanol synthesis produce ethers, alcohols, and aldehydes, which affect the results of the potassium permanganate test on the products ； 2. Organic acids generated as side reactions in methanol synthesis affect the acidity of the product ； 3. Higher alcohols and paraffins produced as side reactions in methanol synthesis affect the product’s water solubility test ； 4. All of the above substances can cause the levels of carbonyl compounds in the methanol product to exceed the specified limits.
