Taw qhia
4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) yog cov organic compound. Nws yog dawb crystalline hmoov nrog siab thermal stability thiab huab cua tsis kam.
Cov khoom siv tuaj yeem siv los npaj cov ntaub ntawv polyester zoo nrog kev ua haujlwm siab oxidation thiab kub tsis kam, thiab muaj ntau yam kev siv. Nws tuaj yeem siv los ua tus hloov kho los txhim kho cov khoom ntawm cov ntaub ntawv polyester, xws li ductility, lub zog, thiab huab cua tsis kam. Nws kuj tseem siv tau los ua cov photosensitizer thiab ib qho ntxiv rau polymerization catalysts.
Txoj kev npaj ntawm 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis (1,2-benzenedicarboxylic acid) yog complex thiab yuav tsum tau los ntawm ntau cov kauj ruam cov tshuaj tiv thaiv. Ib txoj kev siv feem ntau yog ua kom phthalic acid nrog methylene trifluoride nyob rau hauv alkaline tej yam kev mob muab 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Cov ntaub ntawv kev nyab xeeb: Cov txheej txheem tuav tsim nyog thiab kev ceev faj yuav tsum tau ua thaum npaj thiab siv cov khoom sib xyaw no. Nws muaj qee yam toxicity thiab khaus khaus, thiab yuav tsum zam kom tsis txhob nqus cov plua plav thiab nkag mus rau hauv daim tawv nqaij, qhov muag, thiab lwm yam. Hnav cov hnab looj tes tiv thaiv, qhov ncauj qhov ntswg, thiab tsom iav kom muaj cua zoo thaum ua haujlwm.
