Isicelo somkhiqizo:
I-1.I-Chemical synthesis: I-Propionic anhydride iyinto ebalulekile yokusetshenziswa kwamakhemikhali amaningi, evame ukusetshenziswa kuma-esters, ama-amide, ukusabela kwe-acylation nokunye ukuhlanganiswa kwezinto eziphilayo.
I-2.I-solvent ye-Organic: I-propionic anhydride ingasetshenziswa njenge-solvent ephilayo yokuchithwa nokulungiswa kwamadayi, ama-resin, amapulasitiki nokunye.
I-3.Inkundla yezemithi: I-propionic anhydride ingasetshenziswa ekuhlanganiseni ezinye izidakamizwa, njenge-finasteride, i-chloramphenicol propionate nokunye.
Ulwazi Lokuphepha:
I-1.Propionic anhydride ingabangela ukucasuka kwamehlo, ukuphefumula kanye nesikhumba; geza ngokushesha ngemva kokuxhumana.
2.Gqoka amagilavu okuzivikela, izibuko kanye nemaski lapho usebenzisa i-propionic anhydride futhi ugcine indawo yokusebenza enomoya omuhle.
I-3.Propionic anhydride iyavutha, gwema ukuthintana nokushisa noma ilangabi elivulekile.
4.Gcina esitsheni esivalekile kude nemithombo yokuthungela kanye nama-oxidising agents.
