    Ukucaciswa

    Izinto Imininingwane
    Ukubukeka Uketshezi olungenambala
    Ubumsulwa ≥99%
    Umbala(Co-Pt) 10
    Ukuhlolwa kwesixazululo se-Ethyl acetate Ufanelekile
    I-Acidity (ku-acetic acid) ≤0.5%
    Amanzi ≤0.2%

    Isicelo

    Isetshenziswa kakhulu kwezokwelapha, udayi, izibulala-zinambuzane nokunye. Ibuye isetshenziselwe izithasiselo zokudla kanye nama-flavour kanye namakha.

    Impahla

    I-Ethyl acetoacetate iwuketshezi olungenambala olunephunga elimnandi lezithelo. Incibilika kalula ku-ethanol, i-ethyl ehter, i-propylene glycol ne-ethyl acetate, futhi inyibilika emanzini njengo-1:12.

    Isitoreji

    Igcinwe endaweni eyomile, enomthunzi, nengena umoya.

    Ukuzinza

    1. Izinzile ngaphansi kwezinga lokushisa elivamile nokucindezela. Izinto ezingahambelani: ama-asidi, ama-alkali, ama-ejenti anciphisayo, ama-oxidizing agents. Kuyisigaba esinobuthi obuphansi. Gwema umhwamuko ophefumulayo kanye nokuthintana nesikhumba.

    Izakhiwo zamakhemikhali: Insomi uma ihlangana ne-ferric chloride. Uma i-hydrolyzed nge-asidi ehlanjululwe noma i-alkali ehlanjululwe, i-acetone, i-ethanol ne-carbon dioxide iyakhiqizwa. Ngaphansi kwesenzo sesisekelo esiqinile, ama-molecule amabili e-acetic acid ne-ethanol akhiqizwa. Lapho ukuncipha kwe-catalytic, kwakheka i-β-hydroxybutyric acid. Ku-ethyl acetoacetate esanda kugaywa, ifomu le-enol libalelwa ku-7% kanti ifomu le-ketone libalelwa ku-93%. Lapho isixazululo se-ethanol se-ethyl acetoacetate sipholile safinyelela ku--78°C, inhlanganisela ye-ketone yancipha esimweni se-crystalline. Uma i-sodium derivative ye-ethyl acetoacetate imisiwe ku-dimethyl ether kanye nenani elincishisiwe kancane legesi eyomile ye-hydrogen chloride lidlula ku--78°C, kungatholakala inhlanganisela ye-oily enol.

    2. Lo mkhiqizo awunabuthi obuncane, ngomlomo wegundane LD503.98g/kg. Kodwa ngokucasuka okumaphakathi kanye ne-anesthesia, imishini yokukhiqiza kufanele ivalwe futhi ifakwe umoya kahle. Ama-operators ahlome ngezinto zokuzivikela.
