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.
Application
Application industry
Medicine / chemical synthesis
Instructions
Potassium hydrogen sulfate is the preparation of ketone peroxide (Dioxirasnes) series of catalysts such as DMD, TFD basic raw materials, ketone peroxide with its mild reaction conditions, efficient oxidation activity, excellent selectivity and opened up the asymmetric reaction and natural drug synthesis of the new path. Asymmetric reaction of olefin catalyst can be in situ oxidation of chiral amine, chiral imine salt polymerization initiator, vinyl acetate, acrylonitrile polymerization; vinyl monomer polymerization; adhesives, Reconcilers.
Hospitals, homes, poultry and aquaculture disinfectants and water quality improvers, soil improvement and remediation / agricultural disinfectants, tap water pre-oxidation, disinfection and sewage treatment , swimming pools and SPA water treatment, electronics micro etchants, wood cleaning ,Paper industry ,food industry , wool shrinkage treatment, cosmetics and daily chemicals.
Effects
Two effects of potassium peroxymonosulfate
1. Disinfection
In the course of the disease, the farmers use many kinds of poison, but they still can not cure the disease. The main reason is that the use of the same disinfectant for the long time leads to the resistance of the pathogenic bacteria. Therefore, in the fish and shrimp refractory disease can not be a good treatment, you can try two consecutive use of potassium peroxymonosulfate products, can kill chlorine or surface active agent and can not kill the pathogens.
For the prevention of Vibrio, bleeding and other diseases，potassium peroxymonosulfate have a better effect, and will not make the original pathogen resistance.
The main field of application in livestock care disinfection, disinfection, disinfection, spa pool dentures family disinfection.
2. Water quality improvement
Peroxymonosulphate can not only kill algae and other plankton, but also can eliminate algae and other biological toxins. Pond culture, the water that is the life of the water field, but also feces, bait and other garbage disposal sites. In particular, the breeding density is too high, the water self-purification capacity is limited, water quality often abnormal, such as black water pumping, thick green water, algae and other conditions. The main application areas aquaculture water improvement, life industrial wastewater treatment, and hospital water treatment，etc.
