1. Izinzile phantsi kobushushu obuqhelekileyo kunye noxinzelelo.Izinto ezingahambelaniyo: i-acids, i-alkali, i-agent yokunciphisa, i-oxidizing agents.Ludidi olunetyhefu ephantsi.Kuphephe ukuphefumla umphunga kwaye udibane nolusu.
Iimpawu zemichiza: Imfusa xa idibana neferric chloride.Xa i-hydrolyzed nge-asidi edibeneyo okanye i-alkali ye-dilute, i-acetone, i-ethanol kunye ne-carbon dioxide yenziwa.Ngaphantsi kwesenzo sesiseko esomeleleyo, iimolekyuli ezimbini ze-acetic acid kunye ne-ethanol ziveliswa.Xa ukuncipha kwe-catalytic, i-β-hydroxybutyric acid yenziwa.Kwi-ethyl acetoacetate esanda kutshatyalaliswa, ifom ye-enol yenza i-7% kunye ne-ketone form i-93%.Xa isisombululo se-ethanol se-ethyl acetoacetate sipholile ukuya kwi-78 ° C, i-ketone compound yatshitshiswa kwi-crystalline state.Ukuba i-sodium derivative ye-ethyl acetoacetate inqunyanyisiwe kwi-dimethyl ether kunye nexabiso elincinci elincinci le-hydrogen chloride eyomileyo ligqithiswa kwi-78 ° C, i-oily enol compound inokufumaneka.
2. Le mveliso inetyhefu encinci, ngomlomo wempuku LD503.98g/kg.Kodwa ngokucaphuka okuphakathi kunye ne-anesthesia, izixhobo zokuvelisa kufuneka zitywinwe kwaye zifakwe kakuhle.Abaqhubi baxhotyiswe ngezixhobo zokukhusela.
