Kev siv ntawm Potassium hydroxide

Potassium Hydroxide, Potassium hydroxide (KOH) yog qhov yooj yim heev, tsim cov tshuaj alkaline hauv dej thiab lwm cov kuab tshuaj polar.Cov kev daws teeb meem no muaj peev xwm deprotonating ntau cov kua qaub, txawm tias tsis muaj zog.
Potassium hydroxide yog siv los ua cov xab npum mos, hauv kev txhuam thiab ntxuav, ua cov mordant rau ntoo, hauv dyes thiab colorants, thiab absorbing carbon dioxide.Lwm txoj hauv kev siv caustic potash yog nyob rau hauv kev npaj ntawm ob peb poov tshuaj ntsev, acid-base titrations, thiab nyob rau hauv organic sytheses.Tsis tas li ntawd, KOH yog ib qho electrolyte nyob rau hauv tej yam alkaline cia roj teeb thiab roj hlwb.Potassium hydroxide yog siv nyob rau hauv neutralization cov tshuaj tiv thaiv kom yield poov tshuaj ntsev.Aqueous potassium hydroxide yog ua haujlwm raws li cov electrolyte hauv alkaline roj teeb raws li nickel-cadmium thiab manganese dioxide-zinc.Alcoholic KOH cov kev daws teeb meem kuj tau siv los ua ib txoj hauv kev zoo rau kev ntxuav iav.KOH ua haujlwm zoo hauv kev tsim cov biodiesel los ntawm catalyzing transesterification ntawm triglycerides hauv cov roj zaub.
Potassium hydroxide muaj ntau yam sib txawv thiab siv.
1. Nws feem ntau yog siv los ua ib qho nruab nrab hauv cov txheej txheem kev lag luam, xws li kev tsim cov fertilisers, potassium carbonate los yog lwm yam poov tshuaj ntsev thiab cov tshuaj organic.
2. Nws kuj yog siv rau hauv kev tsim cov tshuaj detergents thiab alkaline roj teeb.
3. Kev siv me me suav nrog cov khoom siv tu dej, cov xim tshem tawm thiab cov tshuaj degreasing.
4. tsim cov kua xab npum;
5. mordant rau ntoo;
6. nqus CO2;
7. mercerizing paj rwb;
8. xim thiab kua roj vanish tshem tawm;
9. electroplating, photoengraving thiab lithography;
10. luam ntawv inks;
11. nyob rau hauv analytical chemistry thiab organic syntheses.
12. Pharmaceutic aid (alkalizer).
