What are the reasons for the high or low pH of crude methanol? The pH of crude methanol is generally between 4 and 7. What factors influence the level of this pH value?
Methanol is weakly acidic, and by-products include formic acid and other substances. The pH value of crude methanol in our company is around 6
Methanol itself is weakly acidic; during the synthesis reaction, side reactions result in the formation of formic acid and acetic acid. Moreover, improper temperature control can lead to an increased production of these acids. Therefore, it is necessary to control the pH of crude methanol by regulating the temperature of the synthesis tower
