The invention relates to a method for the production of an thioacetic acid and salts thereof of formulae (I) and (II), wherein M
n+
represents ammonium or an alkali metal cation, alkaline earth metal cation, aluminum cation or titanium cation, by reacting ketene with hydrogen sulphide in the presence of a nitrogenous base or reacting ketene with an aqueous alkali metal hydrogen sulphide solution. The thioacetic acid thus formed can be, optionally, subsequently transformed into the corresponding salt by reacting it with ammonia or an alkali metal base, alkaline earth metal base, aluminum base or titanium base. The transformation of thioacetic acid and the formation of salt is carried out as a one-pot method.
