1-bromo-3,4,5-trifluorobenzene (CAS # 138526-69-9) Kev taw qhia
Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:
xwm:
1-Bromo-3,4,5-trifluorobenzene yog cov kua tsis muaj xim uas tsis yooj yim volatile ntawm chav tsev kub.
Lub hom phiaj:
1-Bromo-3,4,5-trifluorobenzene yog dav siv hauv cov organic synthesis. Nws cov polarity thiab solubility tuaj yeem siv los ua cov kuab tshuaj hauv cov organic synthesis.
Txoj kev tsim khoom:
1-Bromo-3,4,5-trifluorobenzene feem ntau yog npaj los ntawm brominating 1,3,4,5-tetrafluorobenzene. Thaum 1,3,4,5-tetrafluorobenzene reacts nrog bromine, bromine hloov txoj hauj lwm ntawm fluorine kom tau lub hom phiaj cov khoom.
Cov ntaub ntawv kev ruaj ntseg:
1-Bromo-3,4,5-trifluorobenzene yog ib qho organic compound nrog qee yam toxicity. Kev sib cuag nrog daim tawv nqaij, qhov muag, lossis nqus tau lawv cov vapors tuaj yeem ua rau khaus thiab kub hnyiab. Kev tiv thaiv tus kheej tsim nyog yuav tsum tau ua thaum lub sijhawm ua haujlwm thiab siv, xws li hnav hnab looj tes, tsom iav, thiab cov cuab yeej tiv thaiv ua pa. Qhov sib xyaw no yuav tsum tau muab khaws cia rau hauv lub thawv kaw, tsis txhob sib cuag nrog cov pa oxygen, qhov chaw kub thiab qhov hluav taws kub tiv thaiv kom tsis txhob tawg lossis tawg. Ceev faj thaum lub sij hawm tuav thiab ua raws li txoj kev tuav thiab pov tseg kom raug rau cov tshuaj kom txo tau qhov kev pheej hmoo ntawm kev nyab xeeb.
