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

Intshayelelo

I-2,2-bis (3,4-dimethylphenyl) i-hexafluoropropane i-organic compound kunye ne-chemical formula C20H18F6. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

Indalo:

I-2,2-bis (3,4-dimethylphenyl) i-hexafluoropropane lulwelo olungenambala ukuya kumthubi oluluthuthu olunoxinzelelo oluphantsi lomphunga. Inobunzima be-molecular 392.35g / mol, ubuninzi malunga ne-1.20-1.21g / mL (20 ° C), kunye nendawo yokubilisa malunga ne-115-116 ° C.

Sebenzisa:

I-2,2-bis (3,4-dimethylphenyl) i-hexafluoropropane isetyenziswa ikakhulu njenge-stabilizer kunye ne-preservative for polymers. Inokongezwa kwiimveliso zeplastiki kunye neerabha ukuphucula ukuxhathisa kwe-oxidation kunye nokuxhathisa ukushisa. Ukongeza, inokusetyenziswa kwiimveliso ze-elektroniki ezifana neepolymers ze-thermoplastic, i-adhesives, i-coatings kunye ne-resins.

Indlela:

Ukulungiswa kwe-2,2-bis (3,4-dimethylphenyl) i-hexafluoroppane idla ngokufezekiswa ngokuphendula kwe-fluorination ye-aniline. Okokuqala, i-Aniline isabela nge-hydrofluoric acid ukuze yenze i-aniline fluoride, kwaye emva kwe-electrophilic substitution reaction, i-aniline fluoride isabela nge-trans-carbon tetrafluoride ukwenza imveliso ekujoliswe kuyo.

Ulwazi ngoKhuseleko:

I-2,2-bis (3,4-dimethylphenyl) i-hexafluoropropane inetyhefu ephantsi phantsi kwemisebenzi eqhelekileyo yoshishino. Nangona kunjalo, njengekhemikhali, kusafuneka ukuba ubeke ingqalelo ekusebenziseni ngokukhuselekileyo. Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi. Ngethuba lokusetyenziswa okanye ukugcinwa, ingqwalasela kufuneka ihlawulwe ukugcina kude nomlilo kunye ne-oxidizing agents kwaye ugweme ukudibanisa ne-oxidizing agents ezinamandla kunye ne-acids eqinile. Ukunxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu zokhuselo, iiglasi kunye nempahla yokhuselo kuyacetyiswa xa uphethe le khompawundi.
