Taw qhia
2,5-bis (trifluoromethyl) benzoic acid yog cov organic compound nrog cov tshuaj formula C9H4F6O2. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
- 2,5-bis (trifluoromethyl) benzoic acid yog xim tsis muaj xim rau daj daj crystalline lossis hmoov hmoov.
- Yuav luag insoluble nyob rau hauv dej ntawm chav tsev kub, tab sis soluble nyob rau hauv organic solvents xws li ether thiab dichloromethane.
-Nws muaj zog corrosive thiab pungent tsw.
Siv:
- 2,5-bis (trifluoromethyl) benzoic acid yog ib qho reagent feem ntau siv rau hauv cov organic synthesis, uas tuaj yeem siv los ua cov khoom sib txuas xws li tshuaj, dyes thiab cov ntaub ntawv.
-Nws tuaj yeem siv los ua cov tshuaj tiv thaiv rau cov organic synthesis, xws li aromatization cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv carboxylation.
-Tsis tas li ntawd, nws kuj yog siv rau kev npaj cov khoom siv hluav taws xob thiab kev hloov kho qhov chaw ntawm cov khoom siv kho qhov muag.
Txoj Kev Npaj:
- 2,5-bis (trifluoromethyl) benzoic acid tuaj yeem tsim los ntawm reacting 2,5-difluoromethylbenzoic acid nrog trifluoromethylating reagent (xws li trifluoromethyl chloride).
-Cov tshuaj tiv thaiv no feem ntau yog ua nyob rau hauv ib qho chaw inert thiab siv lub catalyst nyob rau hauv acidic los yog yooj yim tej yam kev mob.
Cov ntaub ntawv kev nyab xeeb:
- 2,5-bis (trifluoromethyl) benzoic acid yog corrosive heev thiab tuaj yeem ua rau mob hnyav thiab puas thaum sib cuag nrog daim tawv nqaij thiab qhov muag.
- Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav thiab khaub ncaws tiv thaiv thaum ua haujlwm.
-Qhov sib xyaw no yuav tsum tau khaws cia kom deb ntawm hluav taws thiab oxidizing cov neeg ua haujlwm, thiab muab tso rau hauv lub thawv kaw kom tsis txhob sib cuag nrog huab cua thiab dej.
-Txoj kev kuaj tshuaj lom neeg muaj kev nyab xeeb yuav tsum tau ua raws thaum siv thiab khaws cia.
