Character
Sodium carbonate yog cov hmoov dawb tsis muaj ntxhiab los yog cov khoom nyob hauv chav tsev kub.Nrog cov dej nqus, nthuav tawm hauv huab cua maj mam nqus 1mol / L dej (kwv yees = 15%).Cov dej muaj xws li Na2CO3.·H2O, Na2CO3·7H2O thiab Na2CO3·10 H2O.
Solubility
Sodium carbonate yog yooj yim soluble hauv dej thiab glycerin.
Cov khoom siv tshuaj
Cov tshuaj aqueous ntawm sodium carbonate yog alkaline thiab corrosive rau ib qho twg, thiab tuaj yeem ua ob npaug nrog cov kua qaub, tab sis kuj nrog qee cov calcium ntsev, barium ntsev ob zaug decompose cov tshuaj tiv thaiv.Cov tshuaj yog alkaline thiab tuaj yeem tig phenolphthalein liab.
Skev ruaj ntseg
Muaj zog ruaj khov, tab sis kuj tuaj yeem decomposed ntawm qhov kub thiab txias, tsim sodium oxide thiab carbon dioxide; Cov huab cua ntev ntev tuaj yeem nqus dej noo thiab carbon dioxide hauv huab cua, tsim sodium bicarbonate, thiab tsim ib qho nyuaj.
Hydrolysis tshuaj tiv thaiv
Vim hais tias sodium carbonate yog hydrolyzed nyob rau hauv ib tug aqueous tov, cov ionized carbonate ions ua ke nrog hydrogen ions nyob rau hauv dej los tsim bicarbonate ions, ua rau txo cov hydrogen ions nyob rau hauv cov tshuaj, tawm hauv ionized hydroxide ions, yog li pH ntawm cov tshuaj yog alkaline.
Cov tshuaj tiv thaiv acid
Sodium carbonate reacts nrog txhua yam acids.Siv hydrochloric acid, piv txwv li. Nyob rau hauv ntau npaum li cas, sodium chloride thiab carbonic acid yog tsim, thiab cov tsis ruaj tsis khov carbonic acid yog tam sim ntawd decomposed rau carbon dioxide thiab dej.
Cov tshuaj tiv thaiv nrog alkali
Sodium carbonate tuaj yeem ua ob zaug decompose nrog calcium hydroxide, barium hydroxide thiab lwm cov hauv paus los ua precipitate thiab sodium hydroxide.Cov tshuaj tiv thaiv no feem ntau siv hauv kev lag luam los npaj cov dej qab zib caustic.
Cov tshuaj tiv thaiv nrog ntsev
Sodium carbonate tuaj yeem ua ob zaug decompose nrog calcium ntsev, barium ntsev, thiab lwm yam, los tsim kom muaj nag lossis daus thiab sodium ntsev tshiab:

Feem ntau muaj ob hom Ammonia Alkaline method thiab Combined Alkaline method .1)Ammonia alkaline txoj kev
Nws yog ib qho ntawm cov txheej txheem tseem ceeb rau kev tsim khoom ntawm Soda Ash .Nws yog tus cwj pwm los ntawm cov khoom xyaw pheej yig, yooj yim muaj thiab rov ua dua ntawm ammonia (tsawg poob; Tsim nyog rau ntau lawm, yooj yim rau kev siv tshuab thiab automation). Txawm li cas los xij, cov khoom siv raw ntawm txoj kev no tsawg, tshwj xeeb tshaj yog NaCl tus nqi.Cov txheej txheem tseem ceeb muaj xws li brine calonia npaj, lime. thiab calcination ntawm hnyav alkali, ammonia rov qab, thiab lwm yam.Cov txheej txheem tshuaj tiv thaiv yog raws li nram no:
CaCO 3＝CaO + CO2↑-Q
CaO + H2O = Ca(OH) 2+Q
NaCl + NH3 + H2O + CO2＝NaHCO3 ↓ + NH4Cl+Q
NaHCO 3＝Na2CO3+CO2↑+H2O↑+Q
NH4Cl + Ca(OH)2 = Ca Cl 2 + NH3 + H2O+Q
2) Cua ombinedAlkaline txoj kev
Nrog ntsev, ammonia thiab carbon dioxide byproducts ntawm hluavtaws ammonia kev lag luam raws li raw cov ntaub ntawv, lub simultaneous zus tau tej cov dej qab zib tshauv thiab ammonium chloride, uas yog, ua ke zus tau tej cov dej qab zib tshauv thiab ammonium chloride, hu ua "combined alkali ntau lawm" los yog "combined alkali" cov tshuaj tiv thaiv tseem ceeb yog:
NaCl + NH3 + H2O + CO2 = NaHCO3 ↓ + NH4Cl
NaHCO3 = Na2CO3+CO2↑+H2O↑
* Raws li lub sijhawm ntxiv cov khoom siv raw thiab qhov sib txawv los nag lossis daus kub ntawm ammonium chloride, muaj ntau cov txheej txheem rau kev ua ke alkali ntau lawm. Peb lub teb chaws feem ntau siv: ib zaug carbonization, ob zaug ammonia absorption, ib ntsev, tsis tshua muaj kub ammonium tawm txheej txheem.
