Ferrous chloride (FECL₃)Thiab ferrous chloride (FECL₂) yog ob daim chlorides tseem ceeb ntawm cov hlau. Muaj ntau qhov sib txawv ntawm lawv cov khoom, cov khoom thiab cov ntawv thov.
| Ntiag tug | Ferrous chloride (FECL₂) | Ferric chloride (FECL₃) |
|---|---|---|
| Kev tshwm sim | Anhydrous khoom: lub teeb ntsuab muaju; Yuav tig tsaus ntsuab thaum hygroscopic. | Anhydous khoom: tan-xim av muaju; Yooj yim deliquesces rau hauv cov xim liab-xim av. |
| So | Heev soluble hauv dej (ua cov teeb ntsuab teeb ntsuab); soluble hauv ethanol thiab methanol. | Heev soluble hauv dej (ua cov xim daj lossis liab-xim av, muaj zog acidic); soluble hauv cov kuab tshuaj organic. |
| Melting \/ boiling point | Melting taw tes: ~ 674 degree; Boint Taw tes: ~ 1023 Qib (Decomposes). | Melting taw tes: ~ 306 degree; BOARDING NTAM: ~ 315 degree (sublimes, decomposes rau hauv fecl₂ thiab clr. |
| Crystal Qauv | Hexagonal Crystal system nrog cov yam ntxwv sib txawv ionic. | Fawm txheej txheej nrog ob qho tib si ionic thiab kev sib tw sib cog lus; nquag los tsim polymer molecules (piv txwv li Fe₂cl₆). |
Ferrous chloride (FECL₃)
Chaw thov
Hlau 3 chloride:
- Siv cov flocculant high-efficiency nyob rau hauv kev kho dej (adsorbing impurities los ntawm FE (OH) ₃ colloids tsim los ntawm hydrolysis);
- Catalysts hauv cov synthic synthesis (xws li alkylation ntawm cov ntxhiab hydrocarbons);
- Cov ntawv luam tawm cov board (PCB) Etchant (hnov mob nrog CU kom yaj tooj liab);
- Siv nyob rau hauv cov tshuaj rau hemostatic lossis antiperspirant;
- Extract cov khoom muaj nqis sib xws (xws li kub thiab nyiaj) los ntawm kev lag luam metallurgical.
Hlau 2 chloride:
- Siv los npaj lwm cov hlau sib txuas (xws li fe₃o₄);
- Raws li tus neeg sawv cev txo qis (xws li kev kho ntawm chromium-muaj dej khib nyiab);
- Ua mottled tus neeg sawv cev hauv kev luam ntawv thiab dyeing kev lag luam;
- Nws yog siv nyob rau hauv kev ua liaj ua teb los kho cov hlau tsis muaj mob yelitis hauv nroj tsuag.
Fe²⁺ yog txo, Fe³⁺ yog oxidizing. Qhov kev sib txawv no ua rau muaj qhov sib txawv tseem ceeb ntawm ob hauv cov khoom siv lub cev, tshuaj lom neeg thiab siv cov kev siv.
