Abstract

The composition of the vapor and liquid phases of the KOH + CH3OH system has been studied by the gas chromatography (GC) method at 25 °C. It has been found that the methanol vapor concentration, and the quantity of potassium methoxide formed as a result of the acid–base reaction of potassium hydroxide with methanol, both depend on the KOH/CH3OH mole ratio. The maximum mass fraction of potassium methoxide that forms is 2.6% at the mole ratio 0.018.
