Taw qhia
3-(trifluoromethyl) pyridine, tseem hu ua 1-(trifluoromethyl) pyridine, yog cov organic compound.
Zoo:
3-(trifluoromethyl) pyridine yog cov kua tsis muaj xim uas muaj ntxhiab tsw muaj zog. Nws yog soluble hauv ntau cov kuab tshuaj organic xws li ethanol, dimethylformamide, thiab dimethyl sulfoxide.
Siv:
3-(trifluoromethyl) pyridine yog dav siv los ua catalysts, kuab tshuaj thiab reagents hauv organic synthesis. Nws tuaj yeem siv los ua boron chloride reagent hauv kev sib txuas ntawm cawv, acids, thiab ester derivatives. Nws tseem tuaj yeem siv los ua sodium hydroxide-catalyzed borate esterification reagent rau aldehydes thiab ketones.
Txoj kev:
Muaj ntau txoj hauv kev los npaj 3-(trifluoromethyl) pyridine. Ib txoj hauv kev yog kom tau cov khoom los ntawm cov tshuaj tiv thaiv ntawm pyridine thiab trifluoromethylsulfonyl fluoride. Cov pyridine tau yaj hauv ether hnyav, thiab tom qab ntawd trifluoromethylsulfonyl fluoride tau maj mam ntxiv dropwise. Cov tshuaj tiv thaiv feem ntau yog ua los ntawm qhov kub thiab txias thiab yuav tsum muaj qhov cua txaus kom tsis txhob kis cov pa phem.
Cov Lus Qhia Txog Kev Nyab Xeeb: Nws yog cov kua hluav taws xob uas tuaj yeem ua rau hluav taws tau yooj yim thaum raug cov nplaim taws qhib lossis kub siab. Nws kuj yog ib qho kuab tshuaj organic uas yuav muaj kev cuam tshuam rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Cov hnab looj tes tiv thaiv, tsom iav, thiab cov cuab yeej ua pa yuav tsum tau hnav thaum lub sijhawm ua haujlwm, thiab kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov chaw muaj cua zoo.
