Umenzi weXabiso eliLungileyo ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

Umenzi ngexabiso eliLungileyo ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6 Umfanekiso okhoyo

inkcazelo emfutshane:

I-ACETYL ACETONE, ekwabizwa ngokuba yi-diacetylmethane, i-pentamethylene dione, iphuma kwi-acetone, ifomula yemolekyuli CH3COCH2COCH3, engenambala ukuya kulwelo olukhanyayo olutyheli.I-ACETYL ACETONE idla ngokuba ngumxube we-tautomers ezimbini, i-enol kunye ne-ketone, ezikwi-dynamic equilibrium.Iisomers zeEnol Chemicalbook zenza iibhondi zehydrogen kwimolekyuli.Kulo mxube, i-keto ibala malunga ne-18%, kwaye i-alkenes i-Alcohol ifomu i-82%.Isisombululo se-petroleum ether somxube sipholile ukuya kwi-78 ° C, kwaye ifom ye-enol yatshitshiswa njengento eqinile, ukuze ezo zimbini zihlulwe;xa ifom ye-enol ibuyela kwiqondo lobushushu begumbi, i-ACETYL ACETONE yaba ngokuzenzekelayo kwimeko yokulingana engentla.

Ukusetyenziswa kwe-ACETYL ACETONE

1. I-Pentanedione, eyaziwa ngokuba yi-acetylacetone, iphakathi kwe-fungicides pyraclostrobin, i-azoxystrobin kunye ne-herbicide rimsulfuron.

2. Ingasetyenziswa njengezinto eziluhlaza kunye ne-organic intermediates kumachiza, kwaye ingasetyenziselwa njengezinto ezinyibilikayo.

3. Isetyenziswe njenge-reagent yokuhlalutya kunye ne-agent yokukhutshwa kwe-aluminium kwi-tungsten kunye ne-molybdenum.

4. I-Acetylacetone yinto ephakathi kwi-organic synthesis, kwaye yenza i-amino-4,6-dimethylpyrimidine kunye ne-guanidine, eyona nto ibalulekileyo ye-pharmaceutical material.Ingasetyenziselwa njenge-solvent ye-cellulose acetate, i-additive ye-petroli kunye ne-lubricant, i-desiccant yepeyinti kunye ne-varnish, i-fungicide, kunye ne-insecticide.I-acetylacetone ingasetyenziselwa njenge-catalyst ye-petroleum cracking, i-hydrogenation kunye ne-carbonylation reactions, kunye ne-accelerator ye-oxidation ye-oxygen.Ingasetyenziselwa ukususa ii-oxide zetsimbi kwiindawo eziqinileyo kunye nokunyanga i-polypropylene catalysts.Kumazwe aseYurophu naseMelika, ngaphezu kwama-50% asetyenziswa kwimfuyo yezilwanyana ezilwa norhudo kunye nezongezo zokutya.

5. Ukongeza kwiimpawu eziqhelekileyo zotywala kunye ne-ketones, iphinda ibonise umbala omnyama obomvu kunye ne-ferric chloride kwaye ifake i-chelates ngeetyuwa ezininzi zetsimbi.Nge-acetic anhydride okanye i-acetyl chloride kunye ne-acetone condensation, okanye ngokuphendula kwe-acetone kunye ne-ketene efunyenweyo.I-Chemicalbook isetyenziswa njenge-extractant yesinyithi ukwahlula i-ion ze-trivalent kunye ne-tetravalent, ipeyinti kunye ne-ink driers, i-pesticides, i-pesticides, i-fungicides, i-solvents ye-polymers eziphezulu, i-reagents yokumisela i-thallium, isinyithi, i-fluorine, kunye ne-organic synthesis intermediates.

6. Ii-chelator zetsimbi zenguqu.Ukuzimisela kwe-colorimetric yesinyithi kunye ne-fluorine, kunye nokuzimisela kwe-thallium phambi kwekhabhoni disulfide.

7. Isalathisi se-Fe(III) se-complexometric titration;isetyenziselwa ukuguqulwa kwamaqela e-guanidine (afana ne-Arg) kunye namaqela e-amino kwiiprotheni.

8. Isetyenziswe njenge-agent ye-metal chelating yenguqu;isetyenziselwa ukuzimisela kwe-colorimetric yentsimbi kunye ne-fluorine, kunye nokuzimisela kwe-thallium phambi kwekhabhoni disulfide.

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