The present invention relates to a process for producing monochloroacetic acid by the chlorination of the acetic acid with chlorine gas, in the presence of catalysts, which consists in the fact that the reaction of the acetic acid with chlorine gas is conducted in anhydrous conditions, in organic solvent medium, in the presence of chlorination catalysts consisting of chloroacetyl chloride and / or acetyl chloride and acetic anhydride, at a temperature ranging between 75 and 120‹C, the evaporated volatile fraction being condensated and recirculated continuously in the reaction mass from the lower side, followed by processing the reaction mass |
