Potassium Hydroxide: Potassium hydroxide (kemika: KOH, ka nui o ke ʻano: 56.11) pauka keʻokeʻo a i ʻole ka ʻōpala paʻa. ʻO ke kiko heheʻe he 360 ~ 406 ℃, ʻo ke kiko paila he 1320 ~ 1324 ℃, ʻo ka nui o ka mānoanoa he 2.044g / cm, ʻo ke kiko flash he 52 ° F, ʻo ka refractive index he N20 /D1.421, ʻo ke kaomi mahu he 1mmHg (719 ℃). He alkaline ikaika a ʻawaʻawa. He maʻalahi ke omo i ka makū i ka lewa a me ka deliquescence, a omo i ke kalapona dioxide i loko o ka potassium carbonate. Hoʻoheheʻe ʻia ma kahi o 0.6 ʻāpana wai wela, 0.9 ʻāpana wai anuanu, 3 ʻāpana ethanol a me 2.5 ʻāpana glycerol. Ke hoʻoheheʻe ʻia i loko o ka wai, ka waiʻona, a i ʻole i mālama ʻia me ka waikawa, hoʻopuka ʻia ka nui o ka wela. ʻO ka pH o 0.1mol / L solution he 13.5. ʻO ka toxicity waena, ka nui o ka make ma waena (ʻiole, waha) 1230mg / kg. Hoʻoheheʻe ʻia i loko o ka ethanol, hoʻoheheʻe iki ʻia i loko o ka ether. He alkaline loa ia a ʻinoʻino hoʻi

Nā noi o ka Potassium Hydroxide

ʻO ka Potassium Hydroxide, ʻo Potassium hydroxide (KOH) he kumu kumu kiʻekiʻe, e hana ana i nā hopena alkaline ikaika i ka wai a me nā mea hoʻoheheʻe polar ʻē aʻe. Hiki i kēia mau hopena ke deprotonating i nā waikawa he nui, ʻoiai nā mea nāwaliwali.
Hoʻohana ʻia ka potassium hydroxide e hana i ke kopa palupalu, i ka holoi ʻana a me ka hoʻomaʻemaʻe ʻana, ma ke ʻano he mordant no nā lāʻau, i nā dyes a me nā colorants, a no ka omo ʻana i ke kalapona dioxide. ʻO nā hoʻohana nui ʻē aʻe o ka potash caustic i ka hoʻomākaukau ʻana i kekahi mau paʻakai potassium, nā titrations acid-base, a me nā sytheses orgainic. Eia kekahi, ʻo KOH kahi electrolyte i loko o kekahi mau pila mālama alkaline a me nā cell wahie. Hoʻohana ʻia ka potassium hydroxide i nā hopena neutralization e loaʻa ai nā paʻakai potassium. Hoʻohana ʻia ka potassium hydroxide wai ma ke ʻano he electrolyte i loko o nā pila alkaline e pili ana i ka nickel-cadmium a me ka manganese dioxide-zinc. Hoʻohana pū ʻia nā hopena KOH waiʻona ma ke ʻano he ala kūpono no ka hoʻomaʻemaʻe ʻana i nā aniani. Hana maikaʻi ʻo KOH i ka hana ʻana o ka biodiesel ma o ka hoʻoulu ʻana i ka transesterification o nā triglycerides i loko o ka ʻaila mea kanu.
He nui nā hana a me nā hoʻohana like ʻole o ka potassium hydroxide.
1. Hoʻohana nui ʻia ia ma ke ʻano he waena i nā kaʻina hana ʻoihana, e like me ka hana ʻana i nā mea hoʻouluulu, potassium carbonate a i ʻole nā paʻakai potassium ʻē aʻe a me nā kemika organik.
2. Hoʻohana ʻia nō hoʻi ia i ka hana ʻana i nā mea holoi a me nā pila alkaline.
3. ʻO nā hoʻohana liʻiliʻi e komo pū me nā huahana hoʻomaʻemaʻe ʻauwai, nā mea wehe pena a me nā mea hoʻohemo momona.
4. hana ʻana i ke kopa wai;
5. mea hoʻomāʻū no ka lāʻau;
6. ke omo ʻana i ka CO2;
7. ka pulupulu mercerizing;
8. nā mea wehe pena a me ka varnish;
9. ka electroplating, photoengraving a me ka lithography;
10. nā ʻīnika paʻi;
11. ma ke kemika analytical a me nā synthesis organik.
12. Kōkua lāʻau lapaʻau (alkalizer).
