Taw qhia
Methyl trifluoromethylbenzoate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:
Zoo:
Cov tsos mob: Methyl trifluoromethylbenzoate yog cov kua tsis muaj xim thiab pob tshab.
Solubility: Nws yog soluble hauv ntau cov kuab tshuaj organic xws li ethanol, dimethylformamide, thiab chloroform.
Kub kub stability: ruaj khov ntawm qhov kub thiab txias, tsis yooj yim rau decompose.
Siv:
Methyl trifluoromethylbenzoate feem ntau yog siv los ua ib qho tseem ceeb sib txuas nruab nrab hauv cov organic synthesis.
Nws kuj tseem tuaj yeem siv los tsim cov khoom siv ntxiv hauv polymers thiab txheej.
Nws muaj kev txhawb zog rau cov qoob loo, thiab nws kuj yog siv rau hauv kev ua liaj ua teb.
Txoj kev:
Methyl trifluoromethylbenzoate feem ntau yog tsim los ntawm fluorination ntawm methyl benzoate thiab trifluorocarboxylic acid. Cov txheej txheem no feem ntau yog ua los ntawm qhov kub thiab txias kom tsis txhob muaj qhov tshwm sim ntawm qhov tshwm sim. Tom qab cov tshuaj tiv thaiv, cov khoom ntshiab yog tau los ntawm cov txheej txheem ntawm distillation thiab purification.
Cov ntaub ntawv kev nyab xeeb:
Methyl trifluoromethylbenzoate yog cov kua ua kua thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab kub kub.
Kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav ua rau khaus, thiab yuav tsum tau saib xyuas kom siv cov khoom tiv thaiv tus kheej xws li hnab looj tes thiab tsom iav.
Tsis txhob sib cuag nrog cov oxidants thiab cov kua qaub muaj zog thaum siv thiab khaws cia kom tsis txhob muaj qhov tshwm sim txaus ntshai.
Kev pov tseg pov tseg yuav tsum ua raws li cov cai thiab cov cai hauv zos, thiab yuav tsum tsis txhob muab pov tseg raws li qhov xav tau.
Nyob rau hauv dav dav, methyl trifluoromethylbenzoate yog ib qho tseem ceeb intermediate compound, uas yog dav siv nyob rau hauv tshuaj, tshuaj thiab ua liaj ua teb teb. Thaum siv, kev saib xyuas yuav tsum tau them rau kev ua haujlwm nyab xeeb kom tsis txhob muaj kev cuam tshuam nrog lwm yam tshuaj lom neeg.
