Umkhiqizi Intengo Enhle I-ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

Intengo Enhle Yomkhiqizi I-ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6 Isithombe Esifakiwe

incazelo emfushane:

I-ACETYL ACETONE, eyaziwa nangokuthi i-diacetylmethane, i-pentamethylene dione, iyi-derivative ye-acetone, ifomula yamamolekyuli i-CH3COCH2COCH3, uketshezi olukhanyayo oluphuzi olukhanyayo. I-ACETYL ACETONE ngokuvamile iyingxube yama-tautomers amabili, i-enol ne-ketone, akwi-dynamic equilibrium. Ama-isomers e-Enol Chemicalbook akha ama-hydrogen bond ku-molecule. Engxubeni, i-keto ilinganiselwa ku-18%, kanti i-alkenes Alcohol form ilinganiselwa ku-82%. Isixazululo se-petroleum ether sengxube sapholiswa ku--78°C, futhi ifomu le-enol laqiniswa njenge-solid, ukuze lokhu kokubili kuhlukaniswe; lapho ifomu le-enol libuyela ekushiseni kwegumbi, i-ACETYL ACETONE yayisesimeni sokulingana esingenhla ngokuzenzakalelayo.

Ukusetshenziswa kwe-ACETYL ACETONE

1. I-Pentanedione, eyaziwa nangokuthi i-acetylacetone, iyisithako esiphakathi kwe-fungicides i-pyraclostrobin, i-azoxystrobin kanye ne-herbicide rimsulfuron.

2. Ingasetshenziswa njengezinto zokusetshenziswa kanye nezinto ezisetshenziswayo eziphilayo zemithi, futhi ingasetshenziswa njengezinto zokuncibilikisa.

3. Isetshenziswa njenge-reagent yokuhlaziya kanye ne-ejenti yokukhipha i-aluminium ku-tungsten kanye ne-molybdenum.

4. I-Acetylacetone iyinto ephakathi kokwenziwa kwezinto eziphilayo, futhi yakha i-amino-4,6-dimethylpyrimidine ene-guanidine, okuyizinto ezibalulekile zokusetshenziswa kwemithi. Ingasetshenziswa njenge-solvent ye-cellulose acetate, isithasiselo sephethiloli kanye nezinto zokugcoba, i-desiccant yopende ne-varnish, i-fungicide, kanye ne-insecticide. I-Acetylacetone ingasetshenziswa futhi njenge-catalyst yokuqhekeka kwephethiloli, i-hydrogenation kanye ne-carbonylation reactions, kanye ne-oxidation accelerator ye-oxygen. Ingasetshenziswa ukususa ama-metal oxides ezintweni eziqinile ezinezimbobo kanye nokwelapha ama-polypropylene catalysts. Emazweni aseYurophu naseMelika, angaphezu kwama-50% asetshenziswa emithini yokulwa nohudo kanye nezithasiselo zokudla kwezilwane.

5. Ngaphezu kwezimpawu ezijwayelekile zama-alcohols nama-ketone, ibuye ibonise umbala obomvu omnyama nge-ferric chloride futhi yakha ama-chelates anosawoti amaningi ensimbi. Nge-acetic anhydride noma i-acetyl chloride kanye ne-acetone condensation, noma ngokusabela kwe-acetone ne-ketene okutholiwe. I-Chemicalbook isetshenziswa njenge-metal extractant ukuhlukanisa ama-ion e-trivalent nama-tetravalent, okomisa upende noyinki, izibulala-zinambuzane, izibulala-zinambuzane, izibulala-zinambuzane, izinyibilikisi zama-polymer aphezulu, ama-reagent okunquma i-thallium, insimbi, i-fluorine, kanye ne-organic synthesis intermediates.

6. Ama-chelator ensimbi aguqukayo. Ukunqunywa kwe-colorimetric kwensimbi ne-fluorine, kanye nokunqunywa kwe-thallium lapho kukhona i-carbon disulfide.

7. Inkomba ye-Fe(III) complexometric titration; esetshenziselwa ukuguqulwa kwamaqembu e-guanidine (njenge-Arg) kanye namaqembu e-amino kumaprotheni.

8. Isetshenziswa njenge-ejenti yokuguqula insimbi; isetshenziselwa ukunquma umbala wensimbi ne-fluorine, kanye nokunquma i-thallium lapho kukhona i-carbon disulfide.

9. Inkomba ye-iron (III) complexometric titration. Isetshenziselwa ukuguqula amaqembu e-guanidine kumaphrotheni kanye namaqembu ama-amino kumaphrotheni.
