| Chemical Properties |
Sodium bromate yog cov xim tsis muaj xim lossis dawb crystalline khoom. Tsis hnov tsw. |
| Siv |
Cov bromates ntawm kev lag luam tseem ceeb yog cov sodium thiab potassium. Sodium bromate yog siv nyob rau hauv kev sib tov nrog sodium bromide kom rho tawm kub los ntawm ore. Nws kuj yog siv los ua ib qho kev tshuaj ntsuam reagent, ua tus neeg saib xyuas rau boilers, thiab ua ib feem ntawm cov plaub hau-waving formulations. Potassium bromate feem ntau yog siv los ua cov tshuaj txias rau cov hmoov nplej thiab khob noom cookie; Qee qhov ntawm nws cov khoom siv tsis yog siv xws li siv los ua tus neeg sawv cev oxidizing rau chemistry analytic thiab ua tus neeg sawv cev brominating. Cov bromates ntawm calcium thiab barium muaj kev txwv tsis pub siv oxidizers, maturing agents nyob rau hauv hmoov, thiab analytic reagents. |
| Siv |
Sodium bromate yog siv los ua oxidant los hloov tetrahydropyranyl ethers rau carbonyl compounds. Nws ua raws li kev tshuaj ntsuam reagent. Nws kuj yog siv rau dissolving kub los ntawm nws cov ores, boiler tu, oxidation ntawm leej faj thiab vat dyes. Ntxiv mus, nws yog siv nyob rau hauv cov plaub hau kev kho mob formulations raws li ib tug plaub hau-permanent. |
| Siv |
Raws li kev sib xyaw nrog sodium bromide rau dissolving kub los ntawm nws cov ore. |

| Reactivity Profile |
Sodium bromate yog oxidizing tus neeg sawv cev. Tej zaum yuav hnov mob hnyav nrog combustibles thiab txo cov neeg ua haujlwm. Reacts nrog textiles, roj, roj, roj, qab zib, sawdust thiab ammonium ntsev, carbon, phosphorus, hlau hmoov thiab sulfides uas muaj kev phom sij ntawm hluav taws thiab tawg [Handling Chemicals Safely 1980 p. 831] ib. Ib qho kev sib xyaw ua ke ntawm cov hmoov txhuas sib xyaw nrog cov hmoov sib faib Sodium bromate tawg los ntawm tshav kub, percussion, thiab kev sib txhuam [Meller 2:310 1946-47]. |
| Hazard |
Cov khoom siv oxidizing, phom sij txaus ntshai nyob ze cov ntaub ntawv organic. Toxic los ntawm kev noj. |
| Health Hazard |
Toxic los ntawm kev noj. Kev nqus plua plav yog tshuaj lom. Hluav taws yuav ua rau khaus, corrosive thiab/los yog cov pa phem. Kev sib cuag nrog cov khoom yuav ua rau mob hnyav rau ntawm daim tawv nqaij thiab qhov muag. Cov dej ntws los ntawm kev tswj hluav taws kub lossis dej dilution tuaj yeem ua rau muaj kuab paug. |
| Hluav Taws Xob |
Cov tshuaj no yuav ua kom kub hnyiab thaum koom nrog hluav taws. Tej zaum yuav tawg los ntawm tshav kub los yog paug. Ib txhia yuav hlawv sai heev. Qee tus yuav hnov mob heev nrog hydrocarbons (roj). Tej zaum ignites combustibles (ntoo, ntawv, roj, khaub ncaws, thiab lwm yam). Cov thawv ntim khoom tuaj yeem tawg thaum cua sov. Kev khiav tawm tuaj yeem tsim hluav taws kub lossis tawg. |
| Kev ruaj ntseg Profile |
Cov tshuaj lom los ntawm kev noj tshuaj, intravenous, subcutaneous, thiab intraperitoneal txoj kev. Muaj zog oxidizer. Kev kub ntxhov nrog Al, As, C, Cu, roj, F2, hlau sulfides, organic teeb meem, P, S. lxtures nrog roj yog poob siab-sensitive explosives ntawm 120'C. Thaum rhuab mus rau decomposition nws emits cov pa phem ntawm Na2O thiab Br-. Saib kuj BROMATES. |
| Ntxim yuav nphav raug |
Siv rau kev tshawb fawb thiab kev loj hlob; raws li kev tshuaj ntsuam reagent; rau cais kub ntawm ores; ua vat dyes; boiler ntxuav. |
| Kev xa khoom |
UN1494 Sodium bromate, Hazard Class: 5.1; Cov ntawv lo: 5.1-Oxidizer. UN1450 Bromates, inorganic, nos, Hazard Class: 5.1; Cov ntawv lo: 5.1-Oxidizer, Technical Name Yuav tsum muaj. |
| Txoj kev Purification |
Nws yog crystallized los ntawm dej kub (1.1mL / g) kom txo cov pa paug los ntawm NaBr, bromine thiab hypobromite. [Noszticzius et al. J Am Chem Soc 107 2314 1985.] |
| Kev tsis sib haum xeeb |
Plua plav tuaj yeem tsim tawg sib xyaw nrog huab cua. Lub zog oxidizer muaj peev xwm nce qhov kev siv ntawm qhov hluav taws kub uas twb muaj lawm. Muaj peev xwm hnov mob, tejzaum nws ua nruj ua tsiv, nrog combustible, organic, los yog lwm yam oxidizable cov ntaub ntawv, cawv, glycols, txo cov neeg sawv cev, muaj zog acids, finely faib hlau, tshwj xeeb tshaj yog txhuas. Kev sib kis nrog cov pa roj carbon, cov khoom organic, thiab cov hlau sib xyaw ua kom zoo tuaj yeem ua rau sodium bromate ua rau poob siab. Decomposes ntawm 381 C. Sodium bromate yuav tawg thaum tshav kub kub. |
| Pov tseg pov tseg |
SRP: Txoj haujlwm zoo tshaj plaws ntawm kev nqis tes ua yog siv lwm yam khoom siv tshuaj lom neeg uas muaj qhov tsis zoo rau kev ua haujlwm raug lossis ib puag ncig. Rov ua dua ib feem ntawm cov khoom siv tsis tau siv rau nws qhov kev pom zoo siv lossis xa rov qab mus rau cov chaw tsim khoom lossis tus neeg muag khoom. Qhov kawg pov tseg ntawm cov tshuaj yuav tsum xav txog: cov khoom siv cuam tshuam rau huab cua zoo; muaj peev xwm tsiv teb tsaws hauv av lossis dej; cuam tshuam rau tsiaj, dej, thiab nroj tsuag lub neej; thiab ua raws li kev tswj hwm ib puag ncig thiab kev noj qab haus huv rau pej xeem.
