Soo saaraha Qiimaha Wanaagsan ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

sharaxaad gaaban:

ACETYL ACETONE, oo sidoo kale loo yaqaano diacetylethane, pentamethylene dione, waa ka soo jeeda acetone, qaacidada kelli CH3COCH2COCH3, aan midab lahayn ama iftiin huruud ah oo dareere ah.ACETYL ACETONE inta badan waa isku dhafka laba tautomers, enol iyo ketone, kuwaas oo ku jira dheelitirnaan firfircoon.Enol Chemicalbook isomers waxay sameeyaan curaarta hydrogen ee molecule-ka.Isku darka, keto waxay ku xisaabtamaysaa 18%, iyo alkenes foomka alkoholku wuxuu xisaabiyaa 82%.Xalka ether-ka batroolka ee isku dhafka ah ayaa la qaboojiyey ilaa -78 ° C, qaabka enol-ka ayaa loo soo dajiyay sidii mid adag, sidaas darteed labada waa la kala saaray;markii foomka enolku uu ku soo noqday heerkulka qolka,ACETYL ACETONE si toos ah ayay ugu jirtay xaalada dheellitirka ee sare.

La mid ah:acetyl;Acetyl2-propanone;acetyl-2-propanon;acetyl2-propanone;acetyl-aceton;CH3COCH2COCH3;pentan-2,4-dione;Pentanedione

Codsiyada ACTYL 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.
