    Ukunyibilika Inyibilika kancinci kwi-chloroform kunye ne-methanol.

    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 neeglavu zelabhoratri, iiglasi zokhuseleko, njl.
