Abstract
In obtaining potassium sulphate by the reaction of sodium sulphate decahydrate with potassium chloride, one or both of the initial salts are dissolved in water to obtain a low temperature solution or solutions, such low temperature being maintained during the reaction of the solution with the other dry salt or the solution of the other salt whereby potassium sulphate is precipitated. Alternatively, a substantially dry mixture of potassium chloride and sodium sulphate decahydrate is dissolved in water to obtain a low temperature solution, the low temperature being maintained during the subsequent reaction. According to an example, a mixture of potassium chloride and Glauber's salt is dissolved in water, the initial ingredients being at a temperature of 25 DEG C. The temperature falls to -4 DEG C. and the potassium sulphate which precipitates is recovered. The mother liquor can be evaporated at high temperature to recover potassium chloride which may be used in the process. Heat-insulating vessels may be employed so as to maintain the low temperature obtained for a sufficient time.
