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 o te ethyl acetoacetate ki te dimethyl ether ka tukuna he hau hau hauwai pūhaumāota maroke ki te -78°C, ka taea te whiwhi i te 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.
