Potassium hydroxide, tare da tsarin sinadarai KOH, CAS 1310-58-3, wani fili ne mai ƙarfi wanda ke samun amfani mai yawa a cikin ɗimbin masana'antu. Sau da yawa ana magana da shi azaman potash caustic, wannan kayan hygroscopic yana da tushe mai ƙarfi, wanda ke ba shi damar haɓakawa da ƙarfin da ake buƙata a aikace-aikace da yawa.
Potassium hydroxide wani fari ne mai ƙarfi a zafin jiki kuma yana da tushe mai ƙarfi tare da matakin pH gabaɗaya sama da 12. Yana da narkewa sosai cikin ruwa, yana samar da maganin alkaline mai ƙarfi. Hakanan yana narkewa a cikin ethanol da glycerol, kodayake ba mai narkewa bane a cikin ether da sauran kaushi marasa ƙarfi.
Nauyin kwayoyin halitta na KOH shine kusan 56.11 g/mol.
Yana da wurin narkewar kusan 360°C da wurin tafasar 1,327°C.
Sinadarin yana da matuƙar tsafta, yana ɗaukar ruwa daga iska kuma a hankali yana canzawa zuwa bayani idan an bar shi a fallasa.
Potassium hydroxide yana da nau'ikan aikace-aikace iri-iri, galibi a cikin ayyukan masana'antu. Yana taka muhimmiyar rawa a matsayin tushe mai ƙarfi wajen kera samfura iri-iri. Makullin sa yana amfani da shi:
Masana'antar sabulu da wanki: A cikin tsarin yin sabulu, ana amfani da potassium hydroxide don saɓar mai da mai.
Samuwar Biodiesel: Yana aiki azaman mai haɓakawa a cikin tsarin transesterification.
Masana'antar Abinci: Ana amfani da KOH a cikin shirye-shiryen abinci da sarrafa abinci, musamman azaman mai kauri, wakilin pH, da mai daidaitawa.
Baya ga manyan aikace-aikacen da aka tattauna, potassium hydroxide kuma yana samun amfani a wasu yankuna:
Masana'antar sinadarai: Ana amfani da KOH a cikin samar da mahaɗan sinadarai daban-daban, yana aiki azaman tushe mai ƙarfi a cikin halayen sinadarai.
Masana'antar Harhada magunguna: Ana amfani da shi wajen kera magunguna da dama da hanyoyin magance magunguna.
Noma: Potassium hydroxide ana amfani da shi azaman takin potassium a cikin aikin gona saboda yawan narkewar ruwa.
Samar da Baturi: KOH shine maɓalli mai mahimmanci a cikin batura na alkaline, inda yake aiki azaman electrolyte.
