Abstract: The liquid chlorine is mixed and reacted with an aqueous lye (5) containing an alkali or earth alkali hydroxide and a sulfite or hydrogen sulfite at a reaction temperature of -15 to plus 100 [deg]C and a reaction pressure of 1-40 bar. The liquid chlorine is mixed by a mixer nozzle into a current of lye and the mixture then flows through a reaction section. The temperature of the aqueous lye is preferably at least 10 [deg]C below boiling point of the liquid chlorine at the reaction pressure.
