Isingeniso
Ikhwalithi:
I-Pentafluoropropionic anhydride iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elimnandi. Ayincibiliki emanzini ngamazinga okushisa asekamelweni, incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-acetone, njll. Iwuketshezi oluvuthayo futhi luyavutha.
Sebenzisa:
I-Pentafluoropropionic anhydride isetshenziswa kakhulu ekuphenduleni kwe-fluorination ekuphenduleni kwe-organic synthesis futhi ivame ukusetshenziswa esikhundleni se-hydrofluoric acid.
Indlela:
Indlela yokulungiselela i-pentafluoropropionic anhydride iyinkimbinkimbi kakhulu, futhi indlela evamile iwukusabela nge-fluoroethanol nge-bromoacetic acid ukuze yakhe i-fluoroethyl acetate, bese i-deether ukuze ithole i-pentafluoropropionic anhydride.
Ulwazi Lokuphepha:
I-Pentafluoropropionic anhydride iyacasula futhi ingabangela ukucasuka kwamehlo, umgudu wokuphefumula kanye nesikhumba uma uhogela, ungeniswa, noma uthintana nesikhumba. Ukuhogela umhwamuko wawo kufanele kugwenywe lapho kusetshenziswa noma kwenziwa. Kufanele kuthathwe izinyathelo zokuphepha ezidingekayo, njengokugqoka izingubo zamehlo zokuzivikela namagilavu ezifanele, kanye nokuqinisekisa ukuthi asetshenziswa endaweni enomoya omuhle. Lapho kwenziwa ukusabela kwe-fluorination, izimo zokusabela kufanele zilawulwe ngokuqinile ukuze kugwenywe ukukhiqizwa kwemfucuza ye-fluoride eyingozi.
