Isingeniso
I-2,5-I-Difluorotoluene iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
2,5-I-Difluorotoluene iwuketshezi olungenambala olunephunga elimnandi le-benzene. Ayincibiliki kahle emanzini futhi incibilika kuzincibilikisi zemvelo njenge-ethanol, i-ether ne-benzene. I-2,5-I-Difluorotoluene izinzile emoyeni, kodwa kancane kancane iyabola lapho ibekwe ekukhanyeni.
Sebenzisa:
I-2,5-Difluorotoluene inezinhlobonhlobo zezinhlelo zokusebenza zezimboni. Okwesibili, iphinde isetshenziswe njenge-reagent ye-fluorination ku-organic synthesis, engakwazi ukwethula ama-athomu e-fluorine kuma-molecule, ikhulise umsebenzi wama-molecule futhi iguqule izakhiwo zamakhemikhali. Ngenxa yezakhiwo zayo ezikhethekile zomzimba namakhemikhali, i-2,5-difluorotoluene ingasetshenziswa njenge-solvent kanye ne-ejenti yokukhipha.
Indlela:
Ukuhlanganiswa kwe-2,5-difluorotoluene ngokuvamile kutholakala ngokusabela kwe-fluorinated. Izindlela eziqondile zifaka ukusabela kwe-benzene negesi ye-fluorine lapho kukhona i-ejenti ene-fluorinating eqinile, noma ukusetshenziswa kwe-bisulfate fluoric acid njengomthombo we-fluorine wokusabela kwe-fluorinated.
Ulwazi Lokuphepha:
Uma usebenzisa futhi ugcina i-2,5-difluorotoluene, okulandelayo kufanele kuqashelwe: i-solvent ephilayo, eguquguqukayo futhi kufanele igwenywe ekuhogeleni nasekuthintaneni nesikhumba. Okwesibili, kuyacasula emehlweni, esikhunjeni nasemgudwini wokuphefumula, futhi kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokugqoka izibuko zokuzivikela, ukugqoka izingubo zokuzivikela nokusebenzisa amagilavu okuzivikela. Kufanele isetshenziswe endaweni enomoya omuhle futhi igweme ukuthintana nemithombo yomlilo ukuvimbela izimo ezingalindelekile njengomlilo nokuqhuma.
