Oxidation process for the production of potassium thiosulfate |
| abstract |
An efficient method for the preparation of potassium thiosulfate (K 2 S 2 O 3 ) is described. Potassium hydroxide (KOH) and elemental sulfur (S) are converted to potassium polysulfide, which is subsequently oxidized. The method enables the use of specially designed process conditions such as potassium hydroxide/sulfur molar ratio and temperature to obtain an optimized formulation of the desired polysulfide, and enables the use of a specially designed set of conditions such as temperature, pressure, The oxidant rate and duration achieve a relatively high concentration of a highly pure soluble potassium thiosulfate product with a relatively low amount of by-products. The manufacturing process can be a batch process or a continuous process using a continuous stirred tank reactor (CSTR). The CSTR method relies on several design parameters, including pressure and temperature optimization to avoid product instability. The resulting potassium thiosulfate is a beneficial fertilizer with a high potassium content as a 50% liquid potassium source. |
