Acetylasetone, oo sidoo kale loo yaqaan 2, 4-pentadione, waa isku-dhis dabiici ah, qaacido kiimiko ah C5H8O2, dareere aan midab lahayn ilaa huruud khafiif ah, oo wax yar ku milma biyaha, iyo ethanol, ether, chloroform, acetone, ice acetic acid iyo dareere kale oo dabiici ah oo la isku misi karo, oo inta badan loo isticmaalo dareere ahaan, wakiil soo saar, ayaa sidoo kale loo isticmaali karaa diyaarinta waxyaabaha lagu daro gaaska, saliidaha, cayayaanka caaryada, cayayaanka, rinjiga, iwm.
Guryaha:Acetone waa dareere aan midab lahayn ama huruud yar oo dab qabsan kara. Barta karkarinta waa 135-137 ° C, barta iftiimintu waa 34 ° C, barta dhalaalkuna waa -23 ° C. Cufnaanta qaraabada ah waa 0.976, heerka dhimista waa N20d1.4512. Acetone-ku wuxuu ku milmaa 8g oo biyo ah, waxaana lagu qasaa ethanol, benzene, chloroform, ether, acetone, iyo methampitic acid, waxaana loo kala saaraa acetone iyo acetic acid xalka alkali. Marka ay timaado qandho sare, dab fudud iyo oksaydh xooggan, way fududahay in la gubo. Ma deggana biyaha, si fudud ayaa loogu shubaa acetic acid iyo acetone.

Isticmaalka Acetyl Acettone:
1. Pentanedione, oo sidoo kale loo yaqaan acetylacetone, waa dhexdhexaadka sunta cayayaanka ee pyraclostrobin, azoxystrobin iyo rimsulfuron-ka sunta cayayaanka.
2. Waxaa loo isticmaali karaa walxo ceeriin ah iyo dhexdhexaadin dabiici ah oo loogu talagalay daawooyinka, waxaana sidoo kale loo isticmaali karaa dareere ahaan.
3. Waxaa loo isticmaalaa sidii falanqayn falanqayn iyo wakiil soo saarid ah oo aluminium ah oo ku jira tungsten iyo molybdenum.
4. Acetylacetone waa dhexdhexaad ka mid ah isku-darka dabiiciga ah, waxayna sameysaa amino-4,6-dimethylpyrimidine oo leh guanidine, kaas oo ah walax muhiim ah oo dawooyin cayriin ah. Waxaa loo isticmaali karaa sidii dareere loogu talagalay cellulose acetate, lagu daro gaaska iyo saliidaha, qalajiye rinjiga iyo varnish, fungicidal, iyo cayayaan dilaha.

Waxaa loo isticmaali karaa in laga saaro oksaydhyada birta ah ee ku jira adag ee daloolsan iyo in lagu daaweeyo kiciyeyaasha polypropylene. Wadamada Yurub iyo Ameerika, in ka badan 50% ayaa loo isticmaalaa daawooyinka ka hortagga shubanka xoolaha iyo waxyaabaha lagu daro quudinta.
5. Marka laga soo tago sifooyinka caadiga ah ee khamriga iyo ketones, waxay sidoo kale muujisaa midab casaan madow oo leh ferric chloride waxayna sameysaa chelates oo leh cusbo bir ah oo badan. Iyada oo loo marayo acetic anhydride ama acetyl chloride iyo isku-darka acetone, ama falcelinta acetone iyo ketene ee la helo. Chemicalbook waxaa loo isticmaalaa sidii soo-saare bir ah si loo kala saaro ion-yada trivalent iyo tetravalent, qalajiyaha rinjiga iyo khad, sunta cayayaanka, sunta cayayaanka, fungicides, dareereyaasha polymers-ka sare, reagents si loo go'aamiyo thallium, birta, fluorine, iyo dhexdhexaadiyeyaasha isku-darka dabiiciga ah.
