Umkhiqizi Intengo Enhle I-Potassium Hydroxide CAS:1310-58-3

incazelo emfushane:

I-Potassium Hydroxide : I-Potassium hydroxide (ifomula yamakhemikhali :KOH, inani lefomula :56.11) impushana emhlophe noma i-flake eqinile.Iphuzu elincibilikayo lingu-360 ~ 406℃, indawo yokubilisa ngu-1320 ~ 1324℃, ukuminyana okuhlobene ngu-2.044g/cm, i-flash point ngu-52°F, inkomba ye-refractive ngu-N20/D1.421, umfutho we-vapor ngu-1mmHg (719℃).I-alkaline enamandla futhi iyagqwala.Kulula ukumunca umswakama emoyeni kanye ne-deliquescence, futhi imunce isikhutha ku-potassium carbonate.Incibilika ezingxenyeni ezingaba ngu-0.6 zamanzi ashisayo, izingxenye ezingu-0.9 zamanzi abandayo, izingxenye ezi-3 ze-ethanol nezingxenye ezingu-2.5 ze-glycerol.Uma kuchithwa emanzini, utshwala, noma ukuphathwa nge-asidi, inani elikhulu lokushisa liyakhiqizwa.I-pH yesisombululo esingu-0.1mol/L yayingu-13.5.Ubuthi obumaphakathi, umthamo obulalayo ophakathi (amagundane, ngomlomo) 1230mg/kg.Incibilika ku-ethanol, inyibilika kancane ku-ether.Ine-alkaline ngokwedlulele futhi iyagqwalisa

Izicelo ze-Potassium Hydroxide

I-Potassium Hydroxide, i-Potassium hydroxide(KOH) iyisisekelo kakhulu, yakha izixazululo ze-alkaline ezinamandla emanzini nakwezinye izincibilikisi ze-polar.Lezi zixazululo ziyakwazi ukukhipha ama-asidi amaningi, ngisho nalawo abuthakathaka.
I-Potassium hydroxide isetshenziselwa ukwenza insipho ethambile, ekukhuhleni nasekuhlanzeni, njenge-mordant yezinkuni, kumadayi nama-colorants, kanye nokumunca isikhutha.Okunye ukusetshenziswa kwezimiso ze-caustic potash ekulungiseni usawoti omningi we-potassium, i-acid-base titration, kanye nama-orgainic syntheses.Futhi, i-KOH iyi-electrolyte kumabhethri athile e-alkaline okugcina kanye namaseli kaphethiloli.I-Potassium hydroxide isetshenziselwa ukusabela kwe-neutralization ukukhiqiza usawoti we-potassium.I-aqueous potassium hydroxide isetshenziswa njenge-electrolyte kumabhethri e-alkaline asekelwe ku-nickel-cadmium ne-manganese dioxide-zinc.Izixazululo ze-KOH ezidakayo nazo zisetshenziswa njengendlela ephumelelayo yokuhlanza i-glassware.I-KOH isebenza kahle ekwenzeni i-biodiesel ngokwenza i-transesterification ye-triglycerides emafutheni emifino.
I-Potassium hydroxide inemisebenzi eminingi ehlukahlukene kanye nokusetshenziswa.
1. Ngokuyinhloko isetshenziswa njengendawo emaphakathi ezinqubweni zokukhiqiza ezimbonini, njengokwenziwa komanyolo, i-potassium carbonate noma amanye amasawoti e-potassium namakhemikhali emvelo.
2. Ibuye isetshenziselwe ukwenza izinto zokuhlanza namabhethri ane-alkaline.
3. Ukusetshenziswa okuncane kuhlanganisa imikhiqizo yokuhlanza imfucumfucu, izinto ezikhipha upende kanye nama-agent okukhipha amafutha.
4. ukwenziwa kwensipho ewuketshezi;
5. i-mordant yezinkuni;
6. ukumunca i-CO2;
7. ukotini mercerizing;
8. upende kanye nezikhiphi zokuvanisha;
9. electroplating, photoengraving kanye lithography;
10. oyinki bokunyathelisa;
11. kukhemistri yokuhlaziya kanye nama-organic syntheses.
12. Usizo lwezemithi (alkalizer).
