Taw qhia
Bromotrifluoromethoxybenzene (BTM) yog ib qho organic compound. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb ntawm BTM:
Zoo:
- Cov tsos mob: Bromotrifluoromethoxybenzene yog cov kua tsis muaj xim lossis lub teeb daj.
- ntxhiab tsw: muaj ntxhiab tsw tshwj xeeb.
- Solubility: tuaj yeem yaj hauv cov kuab tshuaj organic xws li ethanol thiab ether.
Siv:
Bromotrifluoromethoxybenzene feem ntau yog siv los ua cov tshuaj tiv thaiv reagent hauv organic synthesis. Nws tuaj yeem siv los ua tus neeg sawv cev phenyl brominating, fluorinating reagent, thiab methoxylating reagent.
Txoj kev:
Txoj kev npaj ntawm bromotrifluoromethoxybenzene feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm bromotrifluorotoluene thiab methanol. Rau cov txheej txheem kev npaj tshwj xeeb, thov xa mus rau phau ntawv qhia ntawm cov organic synthesis chemistry lossis cov ntaub ntawv cuam tshuam ntawm organic chemistry.
Cov ntaub ntawv kev nyab xeeb:
- Bromotrifluoromethoxybenzene ua rau khaus thiab tuaj yeem ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag.
- Tsis txhob nqus cov vapors lossis gases los ntawm cov khoom thiab ua kom nws ua pa zoo.
- Hnav hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv thaum siv.
- Cov tshuaj no yuav tsum tau muab khaws cia rau hauv lub thawv airtight, kom deb ntawm qhov hluav taws kub thiab cua sov, thiab tsis txhob sib cuag nrog oxidants thiab muaj zog acids.
