Ukusetyenziswa
I-potassium hydroxide, eyaziwa ngokuba yi-caustic potash okanye i-potash lye, ikhona ikakhulu kwiindlela ezimbini zoshishino: eqinileyo kunye ne-liquid. Imo eqinileyo ibonakala njengee-flakes ezimhlophe okanye ezingwevu ezikhanyayo, iziqwenga, okanye iintonga, ngelixa imo yolwelo ilulwelo olutyheli olukhanyayo. Iipropati zayo zekhemikhali zifana nezo ze-sodium hydroxide, ine-alkalinity enamandla kunye nokubola. Inyibilika lula emanzini kwaye ikhupha ubushushu obuninzi, ikwabonisa ubushushu obuninzi, oko kuthetha ukuba inokufunxa lula umswakama emoyeni kunye ne-deliquescence, kwaye inokusabela kwi-carbon dioxide ukwenza i-potassium carbonate. Xa inyibilikiswe emanzini, kwi-alcohol, okanye iphathwe nge-asidi, ikhupha ubushushu obuninzi. Isisombululo se-0.1 mol/L sine-pH ye-13.5 (anhydrous). Inetyhefu ephakathi, kunye nedosi ebulalayo ephakathi (yomlomo, kwi-rat) ye-1230 mg/kg. Okwangoku, i-potassium hydroxide isetyenziswa kakhulu ukwenza i-potassium carbonate, i-potassium permanganate, njl.njl., kwaye isetyenziswa kakhulu kwimizi-mveliso yamakhemikhali, yokutya, yamayeza, kunye nezolimo.
I-potassium hydroxide isetyenziswa kakhulu njengezinto eziluhlaza ukuvelisa iityuwa ze-potassium, ezifana ne-potassium permanganate kunye ne-potassium carbonate. Kwishishini lamayeza, isetyenziselwa ukuvelisa i-potassium borohydride, i-Antishutong, i-silybin, i-progesterone, kunye ne-testosterone propionate. Kwishishini lokukhanya, isetyenziselwa ukuvelisa isepha ye-potassium, iibhetri ze-alkaline, kunye nezinto zokuthambisa (ezifana ne-cold cream, i-snow cream, kunye ne-shampoo). Kwishishini ledayi, isetyenziselwa ukuvelisa iidayi ze-vat, ezifana ne-vat blue RSN. Kwishishini le-electrochemical, isetyenziselwa ukufakelwa kwe-electroplating, ukukrola, njalo njalo. Kwishishini lempahla, isetyenziselwa ukuprinta, ukudaya, ukublisha, kunye ne-mercerizing, kwaye ikwasetyenziswa kakhulu njengezinto eziphambili zokwenza iifayibha zokwenziwa kunye neefayibha ze-polyester. Ukongeza, ikwasetyenziswa kwii-heating agents ze-metallurgical kunye ne-leather degreasing, phakathi kwezinye izinto.
