Intshayelelo
Phenyl bromoacetate. Lulwelo olungenambala kunye nevumba elimnandi elingaqhelekanga. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-phenyl bromoacetate:
Umgangatho:
Iphenyl bromoacetate lulwelo oluguquguqukayo olunyibilika kwizinyibilikisi ezininzi eziphilayo, ezifana ne-ethanol, i-ether kunye nebenzene, kwiqondo lobushushu begumbi. Inokungena kwi-hydrolysis reaction ukuvelisa i-terephthalic acid.
Sebenzisa:
I-Phenyl bromoacetate isetyenziswa ngokuqhelekileyo njenge-solvent kunye nephakathi. Isenokusetyenziswa njengento ekrwada yokwaleka, iiplasticizers kunye nezithambisa zelaphu, phakathi kwabanye.
Indlela:
Indlela eqhelekileyo yokulungiswa kwe-phenyl bromoacetate kukusabela kwe-benzoyl bromide kunye ne-ethanol phantsi kweemeko ze-alkaline. Yongeza i-benzoyl bromide kwisisombululo se-alkaline uze wongeze kancinci i-ethanol. Emva kokuba impendulo igqityiwe, imveliso ye-phenyl bromoacetate ifunyenwe nge-distillation.
Ulwazi ngoKhuseleko:
