Intshayelelo
Umgangatho:
I-Pentafluoropropionic anhydride lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elinukayo. Ayinyibiliki emanzini kwiqondo lokushisa, i-soluble kwi-solvents eziphilayo ezifana ne-ethanol, i-acetone, njl njl. Ilulwelo olunokutsha kwaye luyatsha.
Sebenzisa:
I-Pentafluoropropionic anhydride isetyenziswa ngokubanzi kwi-fluorination reactions kwi-organic synthesis reactions kwaye isoloko isetyenziselwa indawo ye-hydrofluoric acid.
Indlela:
Indlela yokulungiselela i-pentafluoropropionic anhydride inzima ngakumbi, kwaye indlela eqhelekileyo kukusabela nge-fluoroethanol nge-bromoacetic acid ukwenza i-fluoroethyl acetate, kwaye emva koko i-deether ukuze ifumane i-pentafluoropropionic anhydride.
Ulwazi ngoKhuseleko:
I-Pentafluoropropionic anhydride iyacaphukisa kwaye inokubangela ukucaphuka kwamehlo, umgudu wokuphefumula kunye nolusu xa ifakwe, ifakwe, okanye idibene nolusu. Ukuphefumla imiphunga yayo kufuneka kuphetshwe xa isetyenziswa okanye iqhutywa. Kufuneka kuthatyathwe amanyathelo okhuseleko ayimfuneko, anjengokunxiba iimpahla zamehlo ezifanelekileyo zokuzikhusela neeglavu, nokuqinisekisa ukuba zisetyenziswa kwindawo engena umoya. Xa usenza i-fluorination reactions, iimeko zokusabela kufuneka zilawulwe ngokungqongqo ukuthintela ukuveliswa kwenkunkuma eyingozi ye-fluoride.
