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 kukhishwa, 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, ingatholakala 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.
