| Aluminium Fluoride Siv Thiab Synthesis |
| Kev piav qhia | Aluminium fluoride yog nyob rau hauv daim ntawv ntawm dawb crystalline khoom los yog ib tug dawb hmoov. Nws tshwm sim ib txwm muaj li minerals rosenbergite thiab oskarssonite.1 Nws kuj tuaj yeem npaj cov khoom siv hluavtaws. |
| Synthesis | Aluminium fluoride yog tsim los ntawm cov txheej txheem hauv qab no: 1) Fluosilicic acid nrog txhuas hydroxide2 H2SiF6 + 2 Al(OH)3 → 2 AlF3 + SiO2 + 4 H2O (I) Cov tshuaj tiv thaiv yog exothermal thiab ua rau ob peb kauj ruam. Nws tuaj yeem piav qhia los ntawm peb qhov kev xav hauv qab no: 3H2SiF6 + 2 Al(OH)3 → Al2(SiF6)3 + 6 H2O (II) Al2(SiF6)3 + 6 H2O → 2 AlF3 + 3 SiO2 + 12 HF (III) 12 HF + 4 Al(OH)3 → 4 AlF3 + 12 H2O Cov tshuaj tiv thaiv yog nqa ntawm 70 ° C thiab 100 ° C. Qhov concentration ntawm fluorosilicic acid tuaj yeem siab li 35 wt% hauv cov kua dej. Raws li cov tshuaj txhuas fluoride ua tau metastable thiab cov trihydrate pib crystalize sai sai ntawm qhov kub ntawm 90 ° C, precipitated khoom silica yuav tsum tau muab tshem tawm sai li sai tau. 2) Al2O3 nrog aqueous hydrofluoric acid3  Hydrofluoric acid yog ntxiv dropwise nyob rau hauv lub zog stirring ntawm chav tsev kub rau Al2O3 ncua kev kawm ntawv. Tom qab ntawd cov khoom oxide yog yaj tag. Lub resulting ntshiab tov yog stirred rau hnub nyob rau hauv chav tsev kub. Thaum lub sij hawm no, cov khoom dawb precipitates raug cais los ntawm cov kuab tshuaj, ntxuav nrog dej, thiab thiaj li qhuav. Tom qab kev kho mob nyob rau hauv ib tug muffle furnace ntawm qhov xav tau calcination kub, aluminium fluoride yog tau. 3) Aluminium alkoxide nrog non-aqueous HF tov4 Aluminium alkoxide, Al(OR) 3 (R=Me, Et, iPr, los yog tBu), reacts nrog non-aqueous HF tov nyob rau hauv cov organic hnyav. Cov tshuaj tiv thaiv yog nqa hauv lub xeev sol-gel. Tom qab aging, ib qho khoom yog tsim uas settles. Cov khoom yog sib cais los ntawm centrifugation thiab qhuav hauv lub tshuab nqus tsev. Gas theem fluorination ntawm cov gel qhuav yog thov kom tau txais txhuas fluoride. |
| Daim ntawv thov | Aluminium fluoride yog ib qho tseem ceeb tshaj plaws additives nyob rau hauv industrial zus tau tej cov txhuas. Kev siv cov txhuas fluoride tuaj yeem txo qhov melting point ntawm cryolite thiab zoo dua lub cev thiab tshuaj lom neeg ntawm electrolyte. Hauv kev tsim cov txhuas, txhuas oxide yog yaj hauv cov tshuaj ntawm cryolite. Los ntawm kev hla cov hluav taws xob tam sim no los ntawm kev daws teeb meem, aluminium yog tsim. Txawm li cas los xij, cov tshuaj cryolite melts ntawm txog 1000 degree. Thaum cov txhuas fluoride ntxiv, electrolysis tuaj yeem tshwm sim hauv cov tshuaj cryolite ntawm qhov kub thiab txias 40-60 degree qis dua, txo qhov yuav tsum tau ntawm lub zog los tsim aluminium.5 Aluminium fluoride yog siv los ua txheej thaiv txheej rau retard oxidation ntawm aluminium iav. 6 Nws yog siv los ua flux hauv ceramic glazes thiab enamels, hauv kev tsim cov txhuas silicate, thiab ua catalyst. Aluminium fluoride complexes nrog cov proteins tuaj yeem siv los kawm txog cov txheej txheem kev hloov pauv ntawm phosphoryl hloov pauv hauv biology, uas yog qhov tseem ceeb xws li phosphoric acid anhydrides xws li ATP thiab GTP tswj feem ntau ntawm cov kev cuam tshuam cuam tshuam hauv metabolism, kev loj hlob thiab kev sib txawv.8 Aluminium fluoride, ua ke nrog zirconium fluoride, yog siv los tsim fluoroaluminate iav. Hauv kev ua liaj ua teb, aluminium fluoride tuaj yeem siv los tiv thaiv fermentation. Lub cev vapor deposited txhuas fluoride yuav siv tau raws li ib tug tsawg Performance index optical nyias zaj duab xis nyob rau hauv lub sij hawm thaum nyob deb UV transparency yuav tsum tau.1 |
| Kev tshawb fawb txog toxicological | Qhov ncauj tsiaj tuag koob tshuaj (LD50) ntawm txhuas fluoride yog 0.1 g/kg. Aluminium fluoride tsis muaj tshuaj lom ntau dua li cov fluorides vim nws cov dej me ntsis solubility. Kev raug rau siab concentration ntawm aluminium fluoride ua rau hypocalcemia. Kev nqus tau thiab noj cov tshuaj txhuas fluoride ua rau cov tsos mob ntawm cov tshuaj fluoride lom. Cov tsos mob ntawm kev ua xua hnyav muaj xws li ua tsis taus pa luv, ua pa ntawm lub ntsws, cov leeg nqaij, thiab convulsions.8 Cov kab mob lom (lub sij hawm luv luv) muaj xws li kev tuag ntawm cov tsiaj, noog, los yog ntses thiab tuag los yog kev loj hlob ntawm cov nroj tsuag. Cov teebmeem tshwm sim tau pom nyob rau hauv 2 mus rau 4 hnub tom qab raug cov tsiaj lossis cov nroj tsuag rau txhuas fluoride. Cov kab mob ntev ntev (ntev) cov tshuaj lom yuav muaj xws li lub neej luv luv, muaj teeb meem kev loj hlob, qis fertility, thiab kev hloov pauv ntawm cov tsos lossis kev coj tus cwj pwm hauv cov tsiaj raug mob. |
| Kev nyab xeeb | Aluminium fluoride yog cov khoom tsis-combustible. Tab sis nws yog incompatible nrog ntau lwm yam khoom xws li tshuaj active hlau (xws li poov tshuaj thiab sodium), kua qaub, thiab kua qaub fumes. Kev sib cuag tuaj yeem ua rau hluav taws kub lossis tawg. Thaum cua sov, cov pa tshuaj fluoride, nrog rau cov tshuaj lom hydrogen fluoride, tuaj yeem tawm. |
