Taw qhia
2- (trifluoromethoxy) fluorobenzene (2- (trifluoromethoxy) fluorobenzene) yog cov organic compound nrog cov tshuaj formula C7H4F4O. Cov hauv qab no yog cov lus piav qhia ntawm cov khoom, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm lub compound:
Xwm:
-Cov tsos mob: 2-(trifluoromethoxy) fluorobenzene yog cov kua tsis muaj xim.
-Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic, xws li ether, chlorinated hydrocarbons.
- Melting point thiab boiling point: Lub melting point yog -30 ° C, thiab boiling point yog 50-51 ° C.
-Density: Qhov ceev ntawm cov compound yog hais txog 1.48g / cm³.
-Kev phom sij: 2-(trifluoromethoxy) fluorobenzene yog cov kua hluav taws xob uas tuaj yeem ua rau hluav taws kub thaum raug hluav taws kub los yog kub kub.
Siv:
-Pharmaceutical Chemistry: 2-(trifluoromethoxy) fluorobenzene tuaj yeem siv los ua ib qho tseem ceeb nruab nrab rau kev npaj tshuaj, tshuaj tua kab thiab lwm yam organic compounds.
-Synthesis ntawm heterocyclic tebchaw: Nws tuaj yeem siv los ua ke ntau yam sib xyaw heterocyclic, xws li hydrogen-muaj heterocycles, nitrogen-muaj heterocycles, thiab lwm yam.
Txoj kev:
2-(trifluoromethoxy) fluorobenzene feem ntau yog npaj los ntawm reacting aryne thiab fluorinating tus neeg saib xyuas, thiab cov kauj ruam tshwj xeeb yog raws li nram no:
1. Lub arylalkyne yog reacted nrog ib tug fluorinating tus neeg sawv cev. Cov tshuaj fluorinating feem ntau yog ammonium hydrogen borate (NH4HF2) thiab hlau fluorides.
2. Qhov nruab nrab tsim los ntawm cov tshuaj tiv thaiv reacts nrog methanol kom tau 2-(trifluoromethoxy) fluorobenzene.
Cov ntaub ntawv kev nyab xeeb:
-Thaum siv thiab khaws cia 2-(trifluoromethoxy) fluorobenzene, ua raws li cov txheej txheem kev nyab xeeb thiab tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab nqus pa ntawm nws cov vapors.
-Cov khoom sib xyaw no yog flammable thiab yuav tsum tau ceev kom deb ntawm hluav taws thiab kub.
- Hnav cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv kom muaj cua zoo thaum tuav cov khoom sib xyaw.
Thov nco ntsoov tias 2-(trifluoromethoxy) fluorobenzene yog cov khoom siv tshuaj, thiab cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li kev ua haujlwm kom tsis txhob muaj xwm txheej thiab raug mob.
