Taw qhia
Bromoacetyl bromide yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm bromoacetyl bromide:
Zoo:
Cov tsos mob: Bromoacetyl bromide yog cov kua tsis muaj xim rau daj ntseg daj.
Solubility: Nws yooj yim soluble hauv cov kuab tshuaj organic, tab sis nws nyuaj rau yaj hauv dej.
Instability: Bromoacetyl bromide decomposes ntawm qhov kub thiab txias los tsim cov pa phem.
Siv:
Bromoacetyl bromide feem ntau yog siv los ua brominating reagent hauv organic synthesis, thiab nws tuaj yeem siv los ua brominating reagent rau ketone-derived compounds.
Nws kuj tseem siv tau rau hauv kev npaj cov kuab tshuaj, catalysts thiab surfactants.
Txoj kev:
Bromoacetyl bromide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm bromoacetic acid nrog ammonium bromide hauv acetic acid:
CH3COOH + NH4Br + Br2 → BrCH2COBr + NH4Br + HBr
Cov ntaub ntawv kev nyab xeeb:
Bromoacetyl bromide yuav tsum tau ua nrog kev tiv thaiv kev tiv thaiv, xws li hnav tsom iav tiv thaiv, hnab looj tes thiab cov tsho tiv no.
Nws yog ib qho tshuaj caustic uas tuaj yeem ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij lossis qhov muag. Yaug nrog dej ntau tam sim ntawd tom qab kis tau thiab nrhiav kev kho mob.
Thaum khaws cia thiab siv bromoacetyl bromide, nws yuav tsum khaws cia kom deb ntawm qhov chaw hluav taws kub thiab qhib nplaim taws, thiab tsis txhob muaj qhov kub thiab txias los tiv thaiv kev tawg thiab tso tawm cov pa phem.
