4-[2-(3 4-dimethylphenyl)-1 1 1 3 3 3-hexafluoropropan-2-yl]-1 2-dimethylbenzene（CAS# 65294-20-4)

Folasaga

2,2-bis (3,4-dimethylphenyl)hexafluoropropane o se faʻalapotopotoga faʻapitoa faʻatasi ma le fua faʻasolosolo C20H18F6. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:

natura:

2,2-bis (3,4-dimethylphenyl)hexafluoropropane o se vai e leai se lanu i le samasama samasama ma le mamafa o le ausa. E iai le mamafa mole mole e 392.35g/mol, e tusa ma le 1.20-1.21g/mL (20°C), ma le vevela e tusa ma le 115-116°C.

Fa'aaogā:

2,2-bis (3,4-dimethylphenyl) hexafluoropropane e masani ona faʻaaogaina e fai ma faʻamautu ma faʻasao mo polymers. E mafai ona faʻaopopo i mea palasitika ma paʻu e faʻaleleia ai le faʻamaʻiina o le faʻamaʻi ma le vevela. E le gata i lea, e mafai foi ona faʻaaogaina i mea faʻaeletoroni e pei o polymers thermoplastic, faʻapipiʻi, faʻapipiʻi ma resini.

Metotia:

O le sauniuniga o le 2,2-bis (3,4-dimethylphenyl) hexafluoroppane e masani lava ona ausia e ala i le fluorination tali o le aniline. Muamua, e tali Aniline i le hydrofluoric acid e fausia ai le aniline fluoride, ona sosoo ai lea ma le electrophilic substitution reaction, e tali atu le aniline fluoride i le trans-carbon tetrafluoride e fausia ai le oloa taulaʻi.

Fa'amatalaga Saogalemu:

2,2-bis (3,4-dimethylphenyl)hexafluoropropane e maualalo le oona i lalo o galuega masani o fale gaosi oloa. Ae ui i lea, i le avea ai o se vailaʻau, e manaʻomia pea le faʻalogo i le faʻaogaina saogalemu. Afai e pa'i i le pa'u po'o mata, fufulu vave i le tele o vai. I le taimi o le faʻaaogaina poʻo le teuina, e tatau ona gauai atu e aloese mai le afi ma mea faʻamaʻi ma aloese mai le faʻafesoʻotaʻi ma vailaʻau malosi faʻamaʻi ma vailaʻau malosi. E fautuaina le ofuina o mea e puipui ai le tagata lava ia e pei o totigilima puipui, matatioata ma lavalava puipui pe a tago i lenei mea.
