摘要:An efficient process for the preparation of magnesium thiosulfate involvesreaction of magnesium hydrosulfite and sulfur at elevated temperature. Magnesiumhydrosulfite can be prepared from commercial magnesium oxide and sulfur. Sulfurdioxide can be used to maintain pH. The resulting product is an emulsion of liquid

magnesium thiosulfate and solid byproducts. Under controlled conditions, including moleratios of MgO to sulfur, temperature of the reaction process, and pH, as well as rate andduration of SOpurging, production of byproducts can be reduced to less than about 2%by weight. The magnesium thiosulfate solution can be prepared -with concentrations ofat least about 25%, preferably at least about 30%.
