    Taupānga

    Ka whakamahia te nuinga ki te rongoa, te waikano, te pesticide me etahi atu. Ka whakamahia ano i roto i 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 wairewa i roto i 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.

    Nga āhuatanga matū: He papura ina tutaki ki te ferric chloride. Ina whakamarohia ki te waikawa waimeha, ki te kawakawa waimeha ranei, ka puta te acetone, te waihano me te hauhā. 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 ethyl acetoacetate ki te -78°C, ka heke te 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 ngawari o te riri me te mate whakahiato, me hiri nga taputapu whakaputa me te pai o te hau. Ko nga kaiwhakahaere he taputapu tiaki.
