| | Chemical Properties | white crystalline powder | | Uses | Oxone is used for halogenation of a,b-unsaturated carbonyl compounds and catalytic generation of hypervalent iodine reagents for alcohol oxidation. It is a used for rapid, and good synthesis of oxaziridines. | | Uses | PCB metal surface treatment chemical and water treatment etc. | | General Description | OXONE, monopersulfate compound is a potassium triple salt mainly used as a stable, easy to handle and nontoxic oxidant. | | Flammability and Explosibility | Non flammable | | reaction suitability | reagent type: oxidant | | Purification Methods | This is a stable form of Caro's acid and should contain >4.7% of active oxygen. It can be used in EtOH/H2O and EtOH/AcOH/H2O solutions. If active oxygen is too low. it is best to prepare it afresh from 1mole of KHSO5, 0.5mole of KHSO4 and 0.5mole of K2SO4. [Kennedy & Stock J Org Chem 25 1901 1960, Stephenson US Patent 2,802,722 1957.] A rapid preparation of Caro's acid is made by stirring finely powdered potassium persulfate (M 270.3) into ice-cold conc H2SO4 (7mL) and when homogeneous add ice (40-50g). It is stable for several days if kept cold. Keep away from organic matter as it is a STRONG OXIDANT. A detailed preparation of Caro's acid (hypersulfuric acid, H2SO5) in crystalline form m ~45o from H2O2 and chlorosulfonic acid was described by Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 388 1963. | | Toxics Screening Level | The initial threshold screening level (ITSL) for acute exposure to pentapotassium bis(peroxymonosulphate) bis(sulphate) (KMPS) is 35 μg/m3 (8-hour averaging time) based on the Michigan Department of Environmental Quality (MDEQ), Air Quality Division (AQD) Rule 336.1233. |
