    • The present invention relates to a continuous process for the manufacture of potassium chlorate by coupling with a plant for the production of sodium chlorate by electrolysis, the said plant comprising a source of NaCl solution, (1), a loop for purification of the said solution (2--2', 3), an electrolysis device (4), a storage tank (5), if appropriate, and a crystallizer (6) in which the crystallization and the separation of NaClO.sub.3 crystals are preferably carried out, wherein circulating liquid is removed downstream of the said electrolysis device (4), a concentrated solution of potassium chloride is added to said liquid, precipitation (11) of the potassium chlorate is caused by any known means, the said potassium chlorate is separated off and the mother liquor from crystallization of the said potassium chlorate is recycled into the said purification loop (2--2', 3) of the sodium chlorate production plant.
    • 本发明涉及通过与用于通过电解生产氯酸钠的设备耦合来制造氯酸钾的连续方法,所述植物包含NaCl溶液源,(1),用于纯化所述溶液的环 (2-2',3),电解装置(4),储存罐(5)以及结晶器(6),其中优选进行NaClO 3晶体的结晶和分离,其中循环液 在所述电解装置(4)的下游除去,向所述液体中加入浓氯化钾溶液,氯化钾的沉淀(11)是以任何已知方法引起的,所述氯酸钾被分离出,母液 从所述氯酸钾的结晶中再循环到氯酸钠生产设备的所述纯化回路(2-2',3)中。
