    Fa'aaogāga

    E masani ona faʻaaogaina i vailaʻau, vali, vailaau faʻasaina ma isi. E faʻaaogaina foʻi i meaʻai faʻaopoopo ma mea manogi ma mea manogi.

    Meatotino

    O le Ethyl acetoacetate o se vai e leai ni lanu ma le manogi suamalie suamalie. E faigofie ona solu i le ethanol, ethyl ehter, propylene glycol ma le ethyl acetate, ma solu i le vai e pei ole 1:12.

    Teuina

    Teuina i se nofoaga mago, paolo, matala.

    Maumau

    1. Stable i lalo o le vevela masani ma le mamafa. Mea e le fetaui: acids, alkalis, fa'aitiitiga fa'aitiitiga, oxidizing agents. O se vaega maualalo-o'ona. Aloese mai le manavaina o le ausa ma faʻafesoʻotaʻi ma le paʻu.

    O mea tau vaila'au: E lanu viole pe a fetaui ma ferric chloride. Pe a fa'asusu i le vai fa'afefete po'o le alkali fa'afefe, e fa'atupuina le acetone, ethanol ma le carbon dioxide. I lalo o le gaioiga a se faʻavae malosi, e lua mole o le acetic acid ma le ethanol e gaosia. Pe a faʻaitiitia faʻamaʻi, faʻapipiʻi le β-hydroxybutyric acid. I totonu o le ethyl acetoacetate fou faatoa fa'amama, o le enol e maua ai le 7% ae o le ketone fomu e 93%. Ina ua malulu le vaifofo o le ethanol o le ethyl acetoacetate i le -78 ° C, o le ketone compound na faʻapipiʻiina i se tulaga tioata. Afai o le sodium derivative o le ethyl acetoacetate o loʻo faʻamalolo le tumau i le dimethyl ether ma o se aofaiga laʻititi laʻititi o le kasa hydrogen chloride kasa e pasia i le -78 ° C, e mafai ona maua se faʻaogaina o le enol suauu.

    2. O lenei oloa e itiiti oona, isumu gutu LD503.98g/kg. Ae faʻatasi ai ma le faʻafefe faʻafefe ma faʻamaʻi faʻamaʻi, e tatau ona faʻamaufaʻailogaina meafaigaluega gaosiga ma faʻaleleia lelei. O lo'o fa'aauupegaina tagata fa'agaoioi mea e puipui ai.
