Umenzi Ixabiso Elihle I-ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

inkcazo emfutshane:

I-ACETYL ACETONE, ekwaziwa ngokuba yi-diacetylmethane, i-pentamethylene dione, yi-derivative ye-acetone, i-molecular formula CH3COCH2COCH3, ulwelo olukhanyayo olungenambala ukuya koluphuzi. I-ACETYL ACETONE idla ngokuba ngumxube wee-tautomers ezimbini, i-enol kunye ne-ketone, ezikwi-dynamic equilibrium. Ii-isomers ze-Enol Chemicalbook zenza ii-hydrogen bonds kwi-molecule. Kumxube, i-keto imalunga ne-18%, kwaye i-alkenes Alcohol form ingama-82%. Isisombululo se-petroleum ether somxube sipholisiwe ukuya kwi--78°C, kwaye i-enol form yaqiniswa njenge-solid, ukuze zombini zahlulwe; xa i-enol form ibuyela kubushushu begumbi, i-ACETYL ACETONE yaya ngokuzenzekelayo kwimeko ye-equilibrium engentla.

Ukusetyenziswa kwe-ACETYL ACETONE

1. I-Pentanedione, ekwaziwa ngokuba yi-acetylacetone, yindawo ephakathi kwe-pyraclostrobin, i-azoxystrobin kunye ne-rimsulfuron ye-herbicide.

2. Ingasetyenziswa njengezinto eziluhlaza kunye nezinto ezisetyenziswa kwizinto eziphilayo kwiimveliso zamayeza, kwaye ingasetyenziswa njengezinto zokunyibilikisa.

3. Isetyenziswa njenge-analytical reagent kunye ne-extraction agent ye-aluminium kwi-tungsten kunye ne-molybdenum.

4. I-Acetylacetone yi-intermediate kwi-organic synthesis, kwaye yenza i-amino-4,6-dimethylpyrimidine ene-guanidine, eyimveliso ebalulekileyo ye-pharmacy. Ingasetyenziswa njengesinyibilikisi se-cellulose acetate, isongezo sepetroli kunye nezinto zokuthambisa, i-desiccant yepeyinti kunye ne-varnish, i-fungicide, kunye ne-insecticide. I-Acetylacetone ingasetyenziswa njenge-catalyst yokuqhekeka kwe-petroleum, i-hydrogenation kunye neempendulo ze-carbonylation, kunye ne-oxidation accelerator ye-oxygen. Ingasetyenziswa ukususa ii-metal oxides kwi-solids ezinemingxuma kunye nokunyanga ii-polypropylene catalysts. Kumazwe aseYurophu naseMelika, ngaphezulu kwe-50% zisetyenziswa kwizilwanyana ezilwa norhudo kunye nezongezo zokutya.

5. Ukongeza kwiipropati eziqhelekileyo ze-alcohols kunye nee-ketones, ikwabonisa umbala obomvu omnyama nge-ferric chloride kwaye yenza i-chelates enetyuwa ezininzi zesinyithi. Nge-acetic anhydride okanye i-acetyl chloride kunye ne-acetone condensation, okanye ngempendulo ye-acetone kunye ne-ketene efunyenweyo. I-Chemicalbook isetyenziswa njenge-metal extractant ukwahlula ii-ion ze-trivalent kunye ne-tetravalent, i-paint and ink driers, i-pesticides, i-pesticides, i-fungicides, i-solvents ze-polymers eziphezulu, ii-reagents zokumisela i-thallium, i-iron, i-fluorine, kunye ne-organic synthesis intermediates.

6. Ii-chelators zesinyithi eziguqukayo. Ukuchonga isinyithi kunye ne-fluorine ngemibala, kunye nokuchonga i-thallium xa kukho i-carbon disulfide.

7. Isalathisi se-Fe(III) complexometric titration; sisetyenziselwa ukuguqula amaqela e-guanidine (afana ne-Arg) kunye namaqela e-amino kwiiproteni.

8. Isetyenziswa njenge-arhente ye-transition metal chelating; isetyenziselwa ukumisela umbala wesinyithi kunye ne-fluorine, kunye nokumisela i-thallium xa kukho i-carbon disulfide.

9. Isalathisi se-iron (III) complexometric titration. Isetyenziselwa ukuguqula amaqela e-guanidine kwiiproteni kunye namaqela e-amino kwiiproteni.
