  Process for the preparation of Kaliumsutftdösung.
 EMI1.1
 So far, the procedure was such that barium sulfide in substance or in solution was combined with a solution of potassium sulfate in the absence of air.



   Here the problem became noticeable that the barium sulfide was added to the
 EMI1.2
   The amount of potassium sulfate is finely ground and the mixture is expediently introduced into boiling water, boiling with or without the use of pressure (which accelerates the reaction
 EMI1.3
   and the reaction is almost quantitative.



     Experiments with showed that the fine grinding of the barium sulfide is not enough
 EMI1.4
 straightness excellent as a starting product of the potassium carbonate production.
