Intshayelelo
I-2,5-i-Difluorotoluene yi-organic compound.
Umgangatho:
I-2,5-Difluorotoluene lulwelo olungenambala kunye nevumba elimnandi lebenzene. Ayinyibiliki kakuhle emanzini kwaye inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether kunye ne-benzene. I-2,5-Difluorotoluene izinzile emoyeni, kodwa iyancipha ngokuthe ngcembe xa ibonakaliswe ekukhanyeni.
Sebenzisa:
I-2,5-i-Difluorotoluene ineendlela ezahlukeneyo zokusetyenziswa kwamashishini. Okwesibini, iphinda isetyenziswe njenge-reagent ye-fluorination kwi-organic synthesis, enokuthi ivelise i-athomu ye-fluorine kwiimolekyuli, ikhulise umsebenzi weemolekyuli kwaye iguqule iimpawu zekhemikhali. Ngenxa yezinto ezikhethekileyo zomzimba kunye neekhemikhali, i-2,5-difluorotoluene ingasetyenziselwa njenge-solvent kunye ne-agent agent.
Indlela:
I-synthesis ye-2,5-difluorotoluene ngokubanzi ifunyenwe ngokusabela kwe-fluorinated. Iindlela ezithile ziquka ukusabela kwe-benzene kunye negesi ye-fluorine xa kukho i-agent eyomeleleyo ye-fluorinating, okanye ukusetyenziswa kwe-bisulfate fluoric acid njengomthombo we-fluorine kwi-fluorinated reactions.
Ulwazi ngoKhuseleko:
Xa usebenzisa kunye nokugcina i-2,5-difluorotoluene, oku kulandelayo kufuneka kuqatshelwe: i-solvent ye-organic, i-volatile kwaye ifanele igwenywe kwi-inhalation kunye nokudibanisa nolusu. Okwesibini, kuyacaphukisa emehlweni, ulusu kunye nomgudu wokuphefumula, kwaye amanyathelo afanelekileyo okukhusela kufuneka athathwe, njengokugqoka iiglasi zokukhusela, ukugqoka iimpahla zokukhusela kunye nokusebenzisa iiglavu zokukhusela. Kufuneka iqhutywe kwindawo engena umoya kwaye igweme ukudibanisa nemithombo yomlilo ukukhusela iimeko ezingalindelekanga ezifana nomlilo kunye nokuqhuma.
