Taw qhia
2-Bromo-5-fluorotrifluorotoluene yog ib qho organic compound.
Nws muaj zog hydrophobicity thiab solubility, thiab muaj kev ruaj ntseg siab. Nws tuaj yeem siv los ua cov tshuaj reagent hauv tshuaj lom neeg thiab feem ntau siv los hloov cov tshuaj tiv thaiv thiab sib txuas cov tshuaj tiv thaiv hauv cov organic synthesis.
Txoj kev npaj ntawm 2-bromo-5-fluorotrifluorotoluene feem ntau yuav ua tau los ntawm reacting trifluorotoluene nrog 2-bromophenylfluoride. Cov tshuaj tiv thaiv tuaj yeem ua tiav nyob rau hauv acidic lossis alkaline, thiab hydrofluoric acid lossis hydrobromic acid uas ua los ntawm cov tshuaj tiv thaiv tuaj yeem rov qab los yog pov tseg los ntawm kev kho nruab nrab.
Nws yog cov kua nplaum uas muaj ntxhiab tsw uas tuaj yeem ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag. Hnav cov cuab yeej tiv thaiv tsim nyog thaum ua haujlwm thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Tsis txhob tiv tauj nrog cov nplaim taws qhib lossis qhov chaw kub. Thaum lub sij hawm cia thiab siv, nws yuav tsum tau muab kaw kom tsis txhob volatilization thiab to los ntawm huab cua. Yog tias muaj qhov xau, kev ntsuas tsim nyog yuav tsum tau ua kom huv thiab pov tseg. Thaum muab pov tseg, nws yuav tsum tau muab pov tseg raws li cov cai hauv zos.
