| Sodium ferrocyanide Siv thiab Synthesis |
| Cov khoom siv tshuaj | Sodium ferrocyanide yog sodium ntsev ntawm kev sib koom ua ke ntawm cov mis [Fe(CN)6]4−. Hauv nws daim ntawv hydrous, Na4Fe(CN)6 • 10H2O (sodium ferrocyanide decahydrate), nws yog qee zaum hu ua daj prussiate ntawm dej qab zib. Nws yog daj crystalline khoom uas yog soluble hauv dej thiab insoluble hauv cawv. Cov xim daj yog xim ntawm ferrocyanide anion. Txawm hais tias muaj cov cyanide ligands, sodium ferrocyanide muaj toxicity tsawg (tau txais txhua hnub 0-0.025 mg / kg lub cev hnyav). Cov ferrocyanides tsis muaj tshuaj lom ntau dua li ntau cov ntsev ntawm cyanide, vim tias lawv nyiam tsis tso tawm dawb cyanide.Txawm li cas los xij, zoo li tag nrho cov tshuaj ntsev ferrocyanide, ntxiv cov kua qaub tuaj yeem ua rau cov roj hydrogen cyanide, uas yog tshuaj lom. |
| Daim ntawv thov |
Sodium hexacyanoferrate (II) decahydrate yog siv thiab kawm ua cov khoom siv cathode rau sodium ion roj teeb. |
| Ntau lawm |
Sodium ferrocyanide yog tsim los ntawm hydrogen cyanide, ferrous chloride, thiab calcium hydroxide, kev sib xyaw ua ke uas muaj peev xwm Ca2[Fe(CN)6] • 11H2O. Kev daws ntawm cov ntsev no yog tom qab ntawd kho nrog sodium ntsev kom precipitate cov calcium-sodium ntsev CaNa2 [Fe (CN) 6], uas nyob rau hauv lem yog kho nrog sodium carbonate muab tetrasodium ntsev. |
| Cia |
Hygroscopic, -20 degree Lub Freezer, Nyob rau hauv inert cua |
| Reactivity |
Sodium ferrocyanide yog ib qho kev sib koom ua ke ntawm hlau. Cov cyanide ligands nruj nreem khi rau cov hlau, yog li nws tsis muaj tshuaj lom li yooj yim inorganic cyanide ntsev. Txawm li cas los xij, qhov sib xyaw no tuaj yeem tso cov roj hydrogen cyanide thaum cov tshuaj tiv thaiv nrog cov kua qaub. |
| tsos |
Sodium ferrocyanide yog daj crystalline ntsev Na4Fe (CN) 6 zoo ib yam li cov poov tshuaj ferrocyanide thiab siv los ua hlau xiav xim, daim ntawv qhia zaub mov, thiab dyes - Hu ua daj prussiate ntawm dej qab zib |
| Chemical Properties | khov kho |
| Siv | Kev tsim cov sodium ferricyanide, xiav pigments, daim ntawv qhia zaub mov, tus neeg sawv cev tiv thaiv rau ntsev, ore flotation, pickling hlau, polymerization catalyst, yees duab kho tus neeg saib xyuas. |
| Siv | Sodium Ferrocyanide yog tus neeg sawv cev tiv thaiv kab mob thiab cov tshuaj tiv thaiv crystallizing. Nws yog qee zaum ntxiv los ua tus neeg sawv cev crystallizing rau ntsev thaum nws crystallizes los tsim lagged thiab loj muaju uas tiv thaiv caking. Nws kuj ua haujlwm ua dej-soluble anticaking agent. |
| Txhais | ChEBI: Sodium hexacyanoferrate (4-) yog hexacyanoferrate ({1}}) ntsev. |
| Kev piav qhia dav dav | Tsis muaj ntxhiab tsw daj. Sinks thiab sib tov nrog dej. |
| Cua & Dej Reactions | Dej soluble. |
| Reactivity Profile | Sodium ferrocyanide muaj zog oxidizing los yog txo hwj chim. Txawm li cas los xij, Redox cov tshuaj tiv thaiv tuaj yeem tshwm sim. Feem ntau ntawm cov tebchaw hauv chav kawm no yog me ntsis soluble lossis insoluble hauv dej. Yog tias soluble hauv dej, ces cov kev daws teeb meem feem ntau tsis muaj zog acidic los yog muaj zog heev. Cov tshuaj no tsis yog dej-reactive. |
| Health Hazard | Tsis muaj sau tseg. |
| Flammability thiab Explosibility | Tsis yog nplaim taws |
| Kev ruaj ntseg Profile | Thaum rhuab mus rau decomposition emits cov pa phem ntawm CN-. |
| Txoj Kev Purification | Crystallize nws los ntawm cov dej kub (0.7mL/g), kom txog thaum tsis muaj ferricyanide raws li qhia los ntawm qhov tsis muaj kev tsim ntawm Prussian Blue xim nrog ferrous sulfate tov. |
