Acetylacetone,oo sidoo kale loo yaqaan 2, 4-pentadione, waa unug dabiici ah, qaacidada kiimikada C5H8O2, aan midab lahayn ama dareere hufnaan ah oo huruud ah, wax yar ku milmaya biyaha, iyo ethanol, ether, chloroform, acetone, acetic acid iyo dareerayaasha kale ee organic qallafsan, inta badan loo isticmaalo sida dareeraha, wakiilka soo saarista, sidoo kale waxaa loo isticmaali karaa diyaarinta waxyaabaha lagu daro shidaalka, saliidaha, cayayaanka caaryada, sunta cayayaanka, midabada, iwm.
Guryaha:Acetone waa mid aan midab lahayn ama wax yar oo huruud ah oo holac kara.Barta karkarinta waa 135-137 ° C, barta iftiimaya waa 34 ° C, barta dhalaaliduna waa -23 ° C. Cufnaanta qaraabada waa 0.976, heerka dhimista waa N20d1.4512.Acetone wuxuu ku milmaa 8g oo biyo ah, waxaana lagu daraa ethanol, benzene, chloroform, ether, acetone, iyo methampitic acid, waxayna u kala go'daa acetone iyo acetic acid ee xalka alkali.Marka ay timaado qandho sare, dab fudud iyo oksidant xooggan, way fududahay in la gubo.Biyo aan degganayn, oo si fudud hydrolyzed galay acetic acid iyo acetone.
Dhexdhexaad u ah isku-dhafka organic:
Acetylacetone waa dhexdhexaad muhiim ah oo ka mid ah isku-dhafka dabiiciga ah, oo si ballaaran loogu isticmaalo daawooyinka, udgoonka, sunta cayayaanka iyo warshadaha kale.
Acetone waa walxo muhiim ah oo ceeriin ah oo ku jira warshadaha dawooyinka, sida isku dhafka 4,6 - dimethylpyrimidine derivatives.Waxa kale oo loo isticmaalaa sida dareere loogu talagalay acetate cellulose, qalajiyaha rinjiga iyo varnishes, iyo reagent falanqayn muhiim ah.
Sababtoo ah jiritaanka qaabka enol, acetylacetone waxay sameyn kartaa chelates leh cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminium, chromium, iron (Ⅱ), copper, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium iyo thorium iyo ion bir kale, kuwaas oo loo isticmaali karo wax lagu daro saliida shidaalka iyo saliida saliidda.
Buugga Kiimikada waxaa loo isticmaali karaa sidii wax lagu nadiifiyo biraha ku jira mikropore-ka iyada oo ay la socoto birta.Loo istcimaalayo kicin ahaan, wakiilka iskutallaabta resin, xawaare daweynta resin;Resin, wax lagu daro caag;Loo isticmaalo falcelinta hydroxylation, falcelinta hydrogenation, falcelinta isomerization, synthesis ketone molecular hoose ee unsaturated iyo polymerization olefin carbon yar iyo copolymerization;Loo isticmaalo sida dareeraha organic, loo isticmaalo acetate cellulose, khad, midab;Wakiilka qalajinta rinjiga;Qalabka ceeriin ee loogu talagalay diyaarinta cayayaanka iyo fungicides, daawooyinka ka hortagga shubanka ee xayawaanka iyo wax lagu daro quudinta;Muraayadda muraayadda infrared, filim hufnaan leh (milix indium), filim superconducting (milix indium) wakiilka samaynta;Isku-dhafka birta acetylacetone wuxuu leeyahay midab gaar ah (cagaaran milix ah, guduud cusbo bir ah, chromium cusbo guduudan) oo aan lagu milmi karin biyaha;Loo isticmaalo sida alaabta ceeriin ee daawada;Qalabka dabiiciga ah ee dabiiciga ah.
Codsiyada ACETYL ACETONE：
1. Pentanedione, oo sidoo kale loo yaqaan acetylacetone, waa dhexdhexaadinta fungicides pyraclostrobin, azoxystrobin iyo herbicide rimsulfuron.
2. Waxaa loo isticmaali karaa sida alaabta ceeriin iyo dhexdhexaadiyaha organic ee farmashiyaha, iyo sidoo kale loo isticmaali karaa sida dareere ah.
3. Loo isticmaalo sidii falanqeeye falanqeeye iyo wakiilka soo saarista aluminium ee tungsten iyo molybdenum.
4. Acetylacetone waa dhex dhexaad u ah isku-dhafka dabiiciga ah, waxayna samaysaa amino-4,6-dimethylpyrimidine oo leh guanidine, taas oo ah alaabta ceeriin ee dawooyinka muhiimka ah.Waxaa loo isticmaali karaa sida dareere loogu talagalay acetate cellulose, wax lagu daro gaaska iyo saliidaha, qalajiyaha rinjiga iyo varnish, fungicides, iyo cayayaanka.Acetylacetone waxa kale oo loo isticmaali karaa kicinta dildilaaca batroolka, hydrogenation-ka iyo falcelinta kaarboonyaynta, iyo dardargeliyaha oksaydhka ee ogsijiinta.Waxa loo isticmaali karaa in laga saaro oksaydhyada biraha ah ee ku jira adkaha dabada ah iyo in lagu daweeyo kicinta polypropylene.Wadamada Yurub iyo Ameerika, in ka badan 50% ayaa loo isticmaalaa daawaynta ka hortagga shubanka xoolaha iyo waxyaabaha lagu daro quudinta.
5. Marka lagu daro sifooyinka caadiga ah ee alkolada iyo ketones, waxay sidoo kale soo bandhigaysaa midabka cas ee madow oo leh ferric chloride waxayna sameysaa chelates leh cusbo badan oo bir ah.By acetic anhydride ama acetyl chloride iyo uumiga acetone, ama falcelinta acetone iyo keene helay.Buuga kimikada waxaa loo isticmaalaa soo saarista birta ah si loo kala saaro trivalent iyo tetravalent ions, rinjiga iyo qalajiyaha qalinka, sunta cayayaanka, sunta cayayaanka, fungicides, dareerayaasha polymers sare, reagents ee go'aaminta thallium, birta, fluorine, iyo dhex abuurka organic.
6. Chelators biraha kala-guurka.Go'aaminta midabka midabka ee birta iyo fluorine, iyo go'aaminta thallium ee joogitaanka kaarboon disulfide.
7. Fe(III) tilmaame titration complexometric;loo isticmaalo wax ka beddelka kooxaha guanidine (sida Arg) iyo kooxaha amino ee borotiinnada.
8. Waxaa loo istcimaalaa sidii wakiilka chelating biraha kala guurka;loo isticmaalo go'aaminta colorimetric ee birta iyo fluorine, iyo go'aaminta thallium ee joogitaanka kaarboon disulfide.
9. Tilmaanta birta (III) titration-ka kakan.Loo isticmaalo in lagu beddelo kooxaha guanidine ee borotiinnada iyo kooxaha amino-yada ee borotiinnada.
Xaaladaha kaydinta:
1. Ka fogow Minghuo iyo oksidant xooggan, xir oo badbaadi.
2. Ku duub bac ama foosto caag ah foosto birta ah, Baakadaha caadiga ah: 200kg / durbaan.Kaydinta iyo gaadiidka iyadoo la raacayo qawaaniinta kiimikooyinka halista ah.
