Potassium Carbonate K2CO3 yog soluble hauv dej, cov tshuaj aqueous yog alkaline; insoluble hauv ethanol, acetone thiab ether. Vim muaj zog hygroscopicity, nws nqus carbon dioxide thiab ya raws thaum raug huab cua thiab tom qab ntawd hloov mus rau hauv potassium bicarbonate.
Feem ntau Potassium carbonate K2CO3 muaj cov tshuaj anhydrous lossis crystals uas muaj 1.5 molecules. Anhydrous ntsev yog dawb granular hmoov, siv lead ua khoom yog dawb translucent me me crystals los yog nplej, tsw, tab sis muaj zog alkali tsw.
Cov txheej txheem ntau lawm
Electrolysis txoj kev: kev daws ntawm poov tshuaj hydroxide yog tau los ntawm electrolysis ntawm poov tshuaj chloride, thaum carbonized nrog carbon dioxide nyob rau hauv lub carbonization ntauwd, peb tau txais poov tshuaj bicarbonate. Tom qab evaporation, pom thiab calcination, peb yuav tau txais poov tshuaj carbonate.
Daim ntawv thov
1) Nws yog tsuas yog siv rau kev tsom xam ntawm reagents, raws li desiccant nyob rau hauv tshuaj thwmsim.
2) Nws yog siv rau hauv kev lag luam zaub mov ua tus neeg sawv cev leavening thiab nws kuj yog siv los ua cov pa roj carbon dioxide, roj hmab antiaging tus neeg saib xyuas, thiab lwm yam.
3) Tsis tas li ntawd, nws kuj yog siv los ua ib qho zoo heev foliar spray fertilizer thiab ib tug constituent ntawm compound fertilizer.
4) Tsuas yog rau thaj chaw thov uas tau hais los saum toj no, nws yog siv rau hauv kev tsim cov khoom siv ceramic, cov khoom siv hauv tsev thiab tshuaj, thiab lwm yam.
