Potassium Hydroxide, Potassium hydroxide(KOH) he kumu nui loa ia, e hana ana i na hooluu alkaline ikaika i ka wai a me na mea hoohehee polar.Hiki i kēia mau hoʻonā ke hoʻopau i nā ʻakika he nui, ʻoiai nā mea nāwaliwali.
Hoʻohana ʻia ka potassium hydroxide no ka hana ʻana i ke kopa palupalu, i ka holoi ʻana a me ka hoʻomaʻemaʻe ʻana, ma ke ʻano he mordant no ka lāʻau, i nā kala a me nā kala, a no ka lawe ʻana i ka carbon dioxide.ʻO nā kumu hoʻohana ʻē aʻe o ka caustic potash i ka hoʻomākaukau ʻana i kekahi mau paʻakai pālolo, titrations acid-base, a me nā sytheses organik.Eia kekahi, he electrolyte ʻo KOH i kekahi mau ʻeke waihona waihona alkaline a me nā wahie.Hoʻohana ʻia ka potassium hydroxide i nā hopena neutralization e hoʻohua i nā paʻakai pālolo.Hoʻohana ʻia ka potassium hydroxide wai ma ke ʻano he electrolyte i nā pākahi 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 ipu aniani.Hana maikaʻi ʻo KOH i ka hana ʻana i ka biodiesel ma o ka hoʻokalakupua ʻana i ka transesterification o nā triglycerides i loko o ka aila meaʻai.
He nui nā hana a me ka hoʻohana ʻana o ka potassium hydroxide.
1. Hoʻohana mua ʻia ʻo ia ma ke ʻano he waena i nā kaʻina hana ʻoihana, e like me ka hana ʻana i nā mea kanu, potassium carbonate a i ʻole nā paʻakai pālolo ʻē aʻe a me nā kinikona.
2. Hoʻohana pū ʻia ia i ka hana ʻana i nā mea holoi a me nā pihi alkaline.
3. ʻO nā mea hoʻohana liʻiliʻi e pili ana i nā huahana hoʻomaʻemaʻe wai, nā mea hoʻohemo pena a me nā mea hoʻoheheʻe.
4. hana ʻana i ke kopa wai;
5. mordant no ka laau;
6. e komo ana i ka CO2;
7. pulupulu mercerizing;
8. pena a me ka varnish wehe;
9. electroplating, photoengraving a me ka lithography;
10. pa'i 'īnika;
11. ma ke kemika analytical a me ka syntheses organik.
12. Kōkua lāʻau lapaʻau (alkalizer).
