Soo-saare Qiimo Fiican ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

sharraxaad gaaban:

ACETYL ACETONE, oo sidoo kale loo yaqaan diacetylmethane, pentamethylene dione, waa nooc ka mid ah acetone, qaacidada molecular CH3COCH2COCH3, dareere hufan oo aan midab lahayn ilaa huruud khafiif ah. ACETYL ACETONE badanaa waa isku darka laba tautomers, enol iyo ketone, kuwaas oo ku jira dheelitirka firfircoon. Isomers-ka Enol Chemicalbook waxay sameeyaan xidhmo hydrogen ah oo ku jira molecule-ka. Isku darka, keto waxay ka dhigan tahay qiyaastii 18%, qaabka alkenes Alcohol-na wuxuu ka dhigan yahay 82%. Xalka batroolka ether ee isku darka ayaa la qaboojiyey ilaa -78°C, qaabka enol-na waxaa lagu soo kiciyay sidii mid adag, si labadooduba loo kala saaro; markii qaabka enol uu ku soo laabtay heerkulka qolka, ACETYL ACETONE waxay si toos ah ugu jirtay xaaladda dheelitirka ee kor ku xusan.

Isticmaalka ACETYL ACETONE

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. Acetylacetone waxaa sidoo kale loo isticmaali karaa sidii kiciye dildilaaca batroolka, falgallada hydrogenation iyo carbonylation, iyo dardar-geliye oksaydh oo loogu talagalay oksijiinta. 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.

6. Chelators-ka birta ee kala-guurka ah. Go'aaminta midabka ee birta iyo fluorine, iyo go'aaminta thallium marka ay jirto kaarboon disulfide.

7. Tilmaanta isku-dhafka ah ee Fe(III); oo loo isticmaalo wax ka beddelka kooxaha guanidine (sida Arg) iyo kooxaha amino ee borotiinnada.

8. Waxaa loo isticmaalaa sidii wakiilka chelating biraha kala-guurka ah; waxaa loo isticmaalaa go'aaminta midabka birta iyo fluorine, iyo go'aaminta thallium marka ay jirto kaarboon disulfide.

9. Tilmaame loogu talagalay titration-ka isku-dhafka ah ee birta (III). Waxaa loo isticmaalaa in lagu beddelo kooxaha guanidine ee borotiinnada iyo kooxaha amino ee borotiinnada.
