Ukusetshenziswa
I-potassium hydroxide, eyaziwa kakhulu ngokuthi i-caustic potash noma i-potassium lye, ikhona ikakhulukazi ngezindlela ezimbili zezimboni: okuqinile kanye noketshezi. Uhlobo oluqinile lubonakala njengama-flakes amhlophe noma ampunga akhanyayo, izingcezu, noma izinduku, kuyilapho uhlobo oluketshezi luwuketshezi oluphuzi olukhanyayo. Izakhiwo zamakhemikhali zalo zifana neze-sodium hydroxide, olune-alkalinity enamandla kanye nokubola. Luncibilika kalula emanzini futhi lukhipha ukushisa okukhulu, futhi lukhombisa ukunambitheka okumnandi, okusho ukuthi lungamunca kalula umswakama emoyeni kanye ne-deliquescence, futhi lungasabela ne-carbon dioxide ukuze lwakhe i-potassium carbonate. Uma luncibilika emanzini, utshwala, noma luphathwe nge-asidi, lukhipha ukushisa okukhulu. Isixazululo esingu-0.1 mol/L sine-pH engu-13.5 (engenamanzi). Sinobuthi obuphakathi, kanye nomthamo obulalayo omaphakathi (ngomlomo, igundane) ongu-1230 mg/kg. Njengamanje, i-potassium hydroxide isetshenziswa kakhulu ukuhlanganisa i-potassium carbonate, i-potassium permanganate, njll., futhi isetshenziswa kakhulu ezimbonini zamakhemikhali, zokudla, zemithi, kanye nezolimo.
I-potassium hydroxide isetshenziswa kakhulu njengezinto zokusetshenziswa ekukhiqizeni usawoti we-potassium, njenge-potassium permanganate kanye ne-potassium carbonate. Embonini yemithi, isetshenziselwa ukukhiqiza i-potassium borohydride, i-Antishutong, i-silybin, i-progesterone, kanye ne-testosterone propionate. Embonini yokukhanya, isetshenziselwa ukukhiqiza insipho ye-potassium, amabhethri e-alkaline, kanye nezimonyo (njengokhilimu obandayo, ukhilimu weqhwa, kanye ne-shampoo). Embonini yodayi, isetshenziselwa ukukhiqiza udayi we-vat, njenge-vat blue RSN. Embonini ye-electrochemical, isetshenziselwa ukugaya nge-electroplating, ukuqopha, njalo njalo. Embonini yezindwangu, isetshenziselwa ukuphrinta, ukudaya, ukufiphaza, kanye ne-mercerizing, futhi isetshenziswa kabanzi njengezinto zokusetshenziswa eziyinhloko zokukhiqiza imicu yokwenziwa kanye nemicu ye-polyester. Ngaphezu kwalokho, isetshenziswa nasezintweni zokushisa zensimbi kanye nokususa amafutha esikhumba, phakathi kwezinye izinhlelo zokusebenza.
