Preparation of Potassium peroxymonosulfate
Potassium peroxymonosulfate preparation process includes three kinds: chlorosulfonic acid method, anodic oxidation method and sulfuric acid method.
Chloroacetic acid: high concentration of hydrogen peroxide (ω> 90%); reaction temperature is too low, energy consumption is large, industrial production must be on the refrigerator can be achieved, and also need to take away from the closed container reaction by-product hydrogen chloride Gas; the reaction of the composite salt mixture obtained after 12 hours centrifugal separation can be obtained, and therefore more difficult to achieve in industrial production.
Anodizing method: to use expensive platinum electrolytic cell, equipment investment, high energy consumption; product was paste, difficult to crystallize. Products at room temperature is very unstable, severe loss of reactive oxygen species, low yield.
We used sulfuric acid method: sulfuric acid and hydrogen peroxide reaction prepared by a sulfuric acid solution, the solution with the basic potassium compounds were prepared by potassium bisulfate complex salt solution, crystallization, filtration and drying, and then mixed with anti-caking agent, the system get the final product.
