Taw qhia
1-Bromo-3,3,3-trifluoroacetone. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:
Zoo:
1-Bromo-3,3,3-trifluoroacetone yog cov kua tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb ntawm chav tsev kub thiab siab. Nws yog soluble hauv cawv, ethers, thiab qee cov organic solvents, thiab insoluble hauv dej. Lub compound muaj siab vapor siab thiab volatility.
Siv:
1-Bromo-3,3,3-trifluoroacetone muaj ntau yam kev siv hauv kev lag luam tshuaj. Ib qho ntawm cov kev siv tseem ceeb yog ua ib qho khoom nruab nrab rau fluoroacetone. Nws kuj yog siv los ua ib qho catalyst rau organic synthesis thiab ua surfactant.
Txoj kev:
Lub synthesis ntawm 1-bromo-3,3,3-trifluoroacetone feem ntau yog ua los ntawm txoj kev bromohydrofluoric acid. Acetone reacted nrog hydrofluoric acid nyob rau hauv lub reactor kom tau bromoacetone. Tom qab ntawd, sodium bromide tau ntxiv rau cov tshuaj tiv thaiv sib xyaw, thiab cov tshuaj tiv thaiv bromination tau ua tiav kom tau 1-bromo-3,3,3-trifluoroacetone. Lub hom phiaj khoom yog tau los ntawm distillation thiab purification.
Cov ntaub ntawv kev nyab xeeb:
1-Bromo-3,3,3-trifluoroacetone ua rau khaus thiab tej zaum yuav muaj teeb meem rau lub qhov muag, tawv nqaij, thiab ua pa. Thaum siv, kev tiv thaiv tus kheej tsim nyog yuav tsum tau siv cov looj tsom iav, hnab looj tes, thiab lub tshuab ua pa. Nws yuav tsum tau siv nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob sib cuag nrog cov khoom xws li muaj zog oxidants.
