Inkcazo yeMveliso yePotassium Peroxymonosulfate
I-Potassium peroxymonosulfate, eyaziwa ngokuba yi-potassium monopersulfate okanye i-potassium peroxodisulfate, i-agent eyomeleleyo ye-oxidizing esetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo.
Ingumgubo omhlophe wekristale onyibilikayo kakhulu emanzini kwaye uzinzile kwiqondo lobushushu begumbi.Olunye lolona setyenziso luqhelekileyo lwe-potassium persulfate lufana ne-oxidizing arhente kwindawo yokuqubha kunye nonyango lwamanzi e-spa.Inceda ukususa ukungcola kwezinto eziphilayo, ibulala ibhaktheriya, iphelisa i-algae kwaye iphucula ukucaca kwamanzi.Ihlala ithengiswa phantsi kwamagama eemveliso ezahlukeneyo kwigranule okanye kwifomu yethebhulethi.I-Potassium peroxymonosulfate ikwasetyenziswa njenge-oxidant kunye ne-disinfectant kwiinkqubo ezahlukeneyo zoshishino ezifana nokucocwa kwamanzi amdaka, i-pulp kunye nephepha, kunye ne-chemical synthesis.
Ukongeza, isetyenziswa kwindawo yelabhoratri ukucoca kunye nokubulala iintsholongwane izixhobo kunye nomgangatho.Kubalulekile ukuthatha amanyathelo okhuseleko afanelekileyo xa uphethe i-potassium sulfate.Inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumla, ngoko ke iiglavu, iiglavu kunye nemaski ziyacetyiswa.Iindlela ezifanelekileyo zokulahla nazo kufuneka zilandelwe ukuthintela ukungcoliseka kwendalo.Kuyafaneleka ukuba uqaphele ukuba i-potassium peroxymonosulfate ayifanele idideke kunye ne-potassium persulfate, enye i-oxidizing agent eneempawu ezifanayo kodwa i-chemical structure kunye nesicelo esahlukileyo.

Ukusetyenziswa kwe-potassium peroxymonosulfate kunye ne-Synthesis
| Iimpendulo |
|
| Iipropati zeMichiza | umgubo omhlophe wekristale |
| Usebenzisa | PCB metal surface unyango imichiza kunye nonyango lwamanzi njl. |
| Usebenzisa | I-Oxone isetyenziselwa ukunyuswa kweekhompawundi ze-a,b-unsaturated carbonyl kunye nesizukulwana esiluncedo se-hypervalent iodine reagents kwi-alcohol oxidation.Isetyenziselwa ukukhawuleza, kunye nokuhlanganiswa okulungileyo kwe-oxaziridines. |
| Inkcazo ngokubanzi | OXONE?, ikhompawundi ye-monopersulfate yityuwa ye-potassium ephindwe kathathu isetyenziswa ikakhulu njengezinzile, kulula ukuyiphatha kunye ne-nontoxic oxidant. |
| Ukutsha kunye nokuSebenza | Ayinakutsha |
| Iindlela zokucoca | Olu luhlobo oluzinzileyo lwe-Caro's acid kwaye kufuneka luqulathe>4.7% yeoksijini esebenzayo.Ingasetyenziswa kwi-EtOH/H2O kunye ne-EtOH/AcOH/H2O izisombululo.Ukuba ioksijini esebenzayo iphantsi kakhulu.kungcono ukuyilungisa ngokutsha ukusuka kwi-1mole ye-KHSO5, i-0.5mole ye-KHSO4 kunye ne-0.5mole ye-K2SO4.[Kennedy & Stock J Org Chem 25 1901 1960, Stephenson US Patent 2,802,722 1957.] Ukulungiswa ngokukhawuleza kweCaro's acid kwenziwa ngokushukumisa umgubo ocolekileyo wepotassium persulfate (M 270.3) kwi-ice-cold conc H2SO4 kunye nomkhenkce (7mL) (40-50g).Iyazinza iintsuku ezininzi ukuba igcinwe ibanda.Zigcine kude nezinto eziphilayo njengoko YI-OXIDANT ENGAMANDLA.Ukulungiswa okucacileyo kwe-Caro's acid (i-hypersulfuric acid, i-H2SO5) kwifom ye-crystalline m ~ 45o esuka kwi-H2O2 kunye ne-chlorosulfonic acid yachazwa nguFehér kwi-Handbook ye-Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 388 1963. |
