Taw qhia
2,2-bis (3,4-dimethylphenyl) hexafluoropropane yog cov organic compound nrog cov tshuaj formula C20H18F6. 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:
2,2-bis (3,4-dimethylphenyl) hexafluoropropane yog cov kua tsis muaj xim rau daj ntseg daj nrog lub siab vapor tsawg. Nws muaj qhov hnyav molecular ntawm 392.35g / mol, qhov ntom ntawm 1.20-1.21g / mL (20 ° C), thiab qhov kub ntawm txog 115-116 ° C.
Siv:
2,2-bis (3,4-dimethylphenyl) hexafluoropropane feem ntau yog siv los ua cov stabilizer thiab preservative rau polymers. Nws tuaj yeem muab ntxiv rau cov khoom yas thiab roj hmab los txhim kho lawv cov oxidation tsis kam thiab kub tsis kam. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv cov khoom siv hluav taws xob xws li thermoplastic polymers, adhesives, coatings thiab resins.
Txoj kev:
Kev npaj ntawm 2,2-bis (3,4-dimethylphenyl) hexafluoroppane feem ntau ua tiav los ntawm fluorination cov tshuaj tiv thaiv ntawm aniline. Ua ntej, Aniline reacts nrog hydrofluoric acid los tsim aniline fluoride, thiab tom qab ntawd tom qab electrophilic hloov cov tshuaj tiv thaiv, aniline fluoride reacts nrog trans-carbon tetrafluoride los tsim cov khoom lag luam.
Cov ntaub ntawv kev nyab xeeb:
2,2-bis (3,4-dimethylphenyl) hexafluoropropane muaj toxicity tsawg nyob rau hauv kev lag luam kev lag luam. Txawm li cas los xij, raws li kev siv tshuaj, nws tseem yuav tsum tau them sai sai rau kev siv nyab xeeb. Nyob rau hauv rooj plaub ntawm cov tawv nqaij los yog ob lub qhov muag, yaug tam sim ntawd nrog dej ntau. Thaum siv lossis khaws cia, yuav tsum tau them nyiaj kom tsis txhob muaj hluav taws kub thiab oxidizing cov neeg ua haujlwm thiab tsis txhob sib cuag nrog cov oxidizing muaj zog thiab cov kua qaub. Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv yog pom zoo thaum tuav cov khoom sib xyaw no.
