A process for the purification of odorous methanol or an odorous methanol-water solution derived from condensates of a kraft pulping process in which the solution is treated with dilute acid. The methanol is concentrated from the treated solution and then treated with an oxidating agent under alkaline conditions after which purified methanol is recovered from the aqueous alkaline solution.
