Mugadziri Mutengo Wakanaka Potassium Hydroxide CAS:1310-58-3

tsananguro pfupi:

Potassium Hydroxide: Potassium hydroxide (makemikari fomura :KOH, huwandu hwefomura :56.11) upfu huchena kana flake solid. Nzvimbo yekunyunguduka i360~406℃, nzvimbo yekufashaira i1320~1324℃, huwandu hwerelative i2.044g/cm, nzvimbo yekupenya i52°F, refractive index iN20 /D1.421, kumanikidzwa kwevapori i1mmHg(719℃). Alkaline yakasimba uye inoparadza. Zviri nyore kunyudza hunyoro mumhepo uye deliquescence, uye kunyudza carbon dioxide mupotassium carbonate. Inonyunguduka muzvikamu zvinenge 0.6 zvemvura inopisa, zvikamu 0.9 zvemvura inotonhora, zvikamu zvitatu zveethanol uye zvikamu 2.5 zveglycerol. Kana yanyungudutswa mumvura, doro, kana yakarapwa neacid, huwandu hwakawanda hwekupisa hunogadzirwa. pH ye0.1mol/L solution yaive 13.5. Chepfu iri pakati nepakati, chiyero chepakati cherufu (makonzo, mukanwa)1230mg/kg. Inonyungudika mu ethanol, inonyungudika zvishoma mu ether. Ine alkaline yakawanda uye inoparadza

Mashandisirwo ePotassium Hydroxide

Potassium Hydroxide, Potassium hydroxide (KOH) chinhu chakareruka zvikuru, chinoita mhinduro dzine alkaline yakasimba mumvura nedzimwe solvents dzine polar. Mhinduro idzi dzinokwanisa kubvisa maasidhi akawanda, kunyangwe asina simba.
Potassium hydroxide inoshandiswa kugadzira sipo yakapfava, mukukwesha nekuchenesa, semushonga wehuni, mumadhayi nemavara, uye mukunyudza carbon dioxide. Mamwe mashandisirwo makuru e caustic potash ndeekugadzira potassium salts dzakawanda, acid-base titrations, uye mu orgain syntheses. Zvakare, KOH i electrolyte mune mamwe mabhatiri ekuchengetera alkaline uye fuel cells. Potassium hydroxide inoshandiswa mu neutralization reactions kuti ibudise potassium salts. Aqueous potassium hydroxide inoshandiswa se electrolyte mumabhatiri e alkaline zvichibva pa nickel-cadmium uye manganese dioxide-zinc. Alcoholic KOH solutions inoshandiswawo senzira inoshanda yekuchenesa girazi. KOH inoshanda zvakanaka mukugadzira biodiesel ne catalyzing transesterification ye triglycerides mumafuta emuriwo.
Potassium hydroxide ine mabasa akasiyana-siyana uye mashandisirwo akasiyana-siyana.
1. Inonyanya kushandiswa senzira yepakati mumabasa ekugadzira maindasitiri, akadai sekugadzira fetereza, potassium carbonate kana mimwe potassium salts uye makemikari eorganic.
2. Inoshandiswawo mukugadzira sipo uye mumabhatiri ane alkaline.
3. Mashandisirwo madiki anosanganisira zvinhu zvinochenesa madhireni, zvinobvisa pendi uye zvinobvisa mafuta.
4. kugadzirwa kwesipo yemvura;
5. mordant yehuni;
6. inonwisa CO2;
7. donje remercerizing;
8. zvinobvisa pendi nevhanishi;
9. electroplating, photoengraving uye lithography;
10. inki dzekudhinda;
11. mukuongorora kemesitiri uye mukugadzirwa kwezvinhu zvakasikwa.
12. Rubatsiro rwemishonga (alkalizer).
