Isicelo seMveliso:
I-1.I-Chemical synthesis: I-anhydride ye-propionic yinto ebalulekileyo ekrwada kwiimpendulo ezininzi zeekhemikhali, ezisetyenziswa ngokuqhelekileyo kwi-esters, i-amides, i-acylation reactions kunye nezinye i-organic synthesis.
I-2.I-solvent ye-Organic: I-anhydride ye-propionic ingasetyenziselwa njenge-solvent ye-organic for dissolution kunye nokulungiswa kwedayi, i-resin, iiplastiki kunye nokunye.
I-3.Intsimi ye-Pharmaceutical: I-anhydride ye-propionic ingasetyenziselwa ukuhlanganiswa kwamanye amachiza, njenge-finasteride, i-chloramphenicol propionate kunye nokunye.
Ulwazi ngoKhuseleko:
I-1.Propionic anhydride inokubangela ukucaphuka kwamehlo, ukuphefumla kunye nolusu; hlamba ngokukhawuleza emva koqhagamshelwano.
2.Nxiba iiglavu ezikhuselayo, iiglasi kunye nemaski xa usebenzisa i-anhydride yepropionic kwaye ugcine indawo yokusebenza enomoya.
I-3.I-anhydride ye-propionic inokutsha, ugweme ukudibanisa nobushushu okanye ilangatye elivulekileyo.
4.Gcina kwisikhongozeli esitywiniweyo kude nemithombo yokutshisa kunye nee-oxidizing agents.
