Soosaaraha Qiimaha wanaagsan ee acetyl acetone (2,4 pentanudedione) CAS 123-54-6 muuqaal muuqaal

Sharraxaadda Gaaban:

Acetyl acetone, oo sidoo kale loo yaqaan diacetylmethethane, pentametylmethethane, pentametylmethethane, pentametylmethethane, ayaa ah mid ka mid ah acetone, qaaciddada molikal2coch2coch2coch2coch2Coch-ka, midab la'aanta ah ee iftiinka huruud huruud ah oo iftiin leh. Acetyl acetone badanaa waa isku dar ah laba tautomers, Enol iyo ketone, kuwaas oo ku jira isleegnaanta firfircoon. Enolflebook-ka-ku-soo-baxa ayaa ka dhigta boldhiciyaha hydrogen-ka ee moleeule. Isku darista, Keto xisaabaadka ku jira qiyaastii 18%, iyo alkenes aalkolada aalkolada akoonnada 82%. Xalka loo yaqaan 'batroolka' petroleum xalka isku dar ah ayaa la qaboojiyey -78 ° C, oo foomka Enol ayaa loo qaboojiyey sidii adkaa oo kale, si labadoodu ay kala tageen; Marka Foomka Enol uu ku soo celiyay heerkulka qolka, acetyl acetone wuxuu si otomaatig ah ugu jiray gobolka kor ku xusan.
