The invention relates to a method for the production of an thioacetic acid and salts thereof of formulae (I) and (II), wherein Mn+ represents ammonium or an alkali metal cation, alkaline earth metal cation, aluminium 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, aluminium base or titanium base. The transformation of thioacetic acid and the formation of salt is carried out as a one-pot method.

L'invention concerne un procédé pour produire un acide thioacétique et ses sels de formules (I) et (II), dans lesquelles M?n+¿ signifie ammonium ou un cation de métal alcalin, de métal alcalino-terreux, d'aluminium ou de titane, du cétène étant transformé avec de l'acide sulfhydrique en présence d'une base azotée ou bien avec une solution aqueuse de sulfure d'hydrogène de métal alcalin. L'acide thioacétique ainsi obtenu peut également ensuite être transformé en un sel correspondant par mise en réaction avec de l'ammoniac ou avec une base de métal alcalin, de métal alcalino-terreux, d'aluminium ou de titane. La transformation en acide thioacétique et la formation du sel sont de préférence réalisées par réaction monotope.
