    Taupānga

    Ka whakamahia te nuinga ki te rongoa, te waikano, te pesticide me etahi atu. Ka whakamahia ano ki nga taapiri kai me nga mea kakara me nga kakara.

    Taonga

    Ko te Ethyl acetoacetate he wai taekore me te haunga hua reka. He ngawari te whakarewa ki te waiwaro, te ethyl ehter, te propylene glycol me te ethyl acetate, ka memeha ki te wai hei 1:12.

    Rokiroki

    Whakaorangia ki te wahi maroke, marumaru, whai hau.

    Te pumau

    1. Pumau i raro i te pāmahana me te pehanga noa. Ko nga mea e kore e hototahi: te waikawa, te kawakore, nga mea whakaheke, nga mea whakahaora. He waahanga iti-paitini. A ape i te hau kohu me te pa ki te kiri.

    Ngā āhuatanga matū: He papura ina tutaki ana ki te ferric chloride. Ina whakamarohia ki te waikawa waimeha, kawakawa waimeha ranei, ka puta te acetone, te waihano me te waro hauhauora. I raro i te mahi a te turanga kaha, ka puta nga ngota ngota e rua o te waikawa ahetiki me te waihano. I te whakahekenga o te catalytic, ka hangaia te waikawa β-hydroxybutyric. I roto i te ethyl acetoacetate hou, ko te ahua o te enol e 7% me te ahua ketone mo te 93%. I te whakamataonga o te wairewa waiwaro o te ethyl acetoacetate ki te -78°C, ka heke te puhui ketone i roto i te ahua tioata. Mēnā ka whakatārewahia te konutai konutai o te ethyl acetoacetate ki te dimethyl ether ka tukuna he hau hau hauwai pūhaumāota maroke ki te -78°C, ka taea te whiwhi pūhui enol hinuhinu.

    2. He iti ake te paitini o tenei hua, kiore waha LD503.98g/kg. Engari me te iti o te riri me te rewharewha, me hiri nga taputapu whakaputa me te pai o te hau. Ko nga kaiwhakahaere he taputapu tiaki.
