Abstract: Mucochloric acid is prepared by a continuous process by the reaction of furfurol with at least 5 moles of gaseous Cl2 per mole of furfurol in aqueous acid medium by continuously supplying the reactants and continuously withdrawing the reaction product, the reaction mixture being circulated at from ambient temperature to 130 DEG C. in a tubular recirculation system, the reactants being supplied at such a rate that the weight ratio of the furfurol added to the reaction mixture which absorbs it is constantly less than a value of 1:100.
