Kaihanga Utu Pai ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

whakaahuatanga poto:

Ko te ACETYL ACETONE, e mohiotia ana ko te diacetylmethane, pentamethylene dione, he takenga mai i te acetone, tauira ngota CH3COCH2COCH3, he kore tae ki te kowhai marama te wai maramara.Ko te ACETYL ACETONE he ranunga o nga tautomers e rua, te enol me te ketone, kei roto i te taurite hihiri.Enol Chemicalbook isomers e hanga here hauwai i roto i te rāpoi ngota.I roto i te ranunga, ko te keto te 18%, me te alkenes Ko te waipiro he 82%.Ko te wairewa eter hinu o te ranunga i whakamatao ki te -78°C, a, ka toia te ahua o te enol hei totoka, kia wehea ai nga mea e rua;i te hokinga mai o te ahua o te enol ki te pāmahana rūma, ka noho aunoa a ACETYL ACETONE ki te ahua taurite i runga ake nei.
