Isicelo seMveliso:
1.I-anhydride yeValeric isetyenziswa kakhulu njenge-reagent kwaye iphakathi kwi-organic synthesis.
2.Ingasetyenziselwa ukulungiselela iikhompawundi kunye namaqela ahlukeneyo asebenzayo, njenge-ethyl acetate, i-anhydride esters kunye ne-amides.
3.I-anhydride yeValeric nayo ingasetyenziswa ekudibaneni kwezinambuzane kunye neziqholo.
Ulwazi ngoKhuseleko:
I-1.I-anhydride ye-Valeric iyacaphukisa kwaye iyancipha, ugweme ukudibanisa nesikhumba kunye namehlo kwaye uqinisekise ukuba iphathwa kwindawo enomoya.
I-2.Ngexesha lokuphatha kunye nokugcinwa, gwema ukudibanisa ne-oxidising agents okanye i-acids eqinile kunye neziseko zokuthintela ukusabela okuyingozi.
3.Landela iinkqubo zokuphatha ngokukhuselekileyo kwiikhemikhali ngexesha lokusebenza kwaye ube nezixhobo ezifanelekileyo zokukhusela ezifana neiglavu zelabhoratri, iiglasi zokhuseleko, njl.
