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

incazelo emfushane:

I-ACETYL ACETONE, eyaziwa nangokuthi i-diacetylmethane, i-pentamethylene dione, iphuma ku-acetone, ifomula ye-molecular CH3COCH2COCH3, engenambala ukuya kuketshezi olukhanyayo olukhanyayo olukhanyayo.I-ACETYL ACETONE imvamisa iyingxube yama-tautomer amabili, i-enol ne-ketone, asekulinganisweni okuguquguqukayo.Ama-isomers e-Enol Chemicalbook akha amabhondi e-hydrogen ku-molecule.Kule ngxube, i-keto yenza cishe u-18%, futhi i-alkenes ifomu le-Alcohol libalelwa ku-82%.Isixazululo se-petroleum ether sengxube sapholiswa ku--78 ° C, futhi ifomu le-enol lancipha njengento eqinile, ukuze lezi ezimbili zihlukaniswe;lapho ifomu le-enol libuyela kuzinga lokushisa legumbi, i-ACETYL ACETONE yaba sesimweni sokulingana esingenhla ngokuzenzakalelayo.

Izicelo ze-ACETYL ACETONE

1. I-Pentanedione, eyaziwa nangokuthi i-acetylacetone, iyisibulala-sikhunta i-pyraclostrobin, i-azoxystrobin kanye ne-herbicide rimsulfuron.

2. Ingasetshenziswa njengezinto ezingavuthiwe kanye ne-organic intermediates kwezemithi, futhi ingasetshenziswa njengezincibilikisi.

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

4. I-Acetylacetone iyingxenye ephakathi kwe-organic synthesis, futhi yakha i-amino-4,6-dimethylpyrimidine ne-guanidine, into ebalulekile yemithi eluhlaza.Ingasetshenziswa njenge-solvent ye-cellulose acetate, isithasiselo sikaphethiloli kanye nezinto zokugcoba, i-desiccant yopende ne-varnish, isibulala-fungi, nesibulala-zinambuzane.I-acetylacetone ingasetshenziswa futhi njenge-catalyst yokuqhekeka kwe-petroleum, i-hydrogenation kanye ne-carbonylation reactions, kanye ne-accelerator ye-oxidation ye-oxygen.Ingasetshenziselwa ukususa ama-oxide ensimbi ezintweni eziqinile nezimbotshana nokwelapha ama-catalyst e-polypropylene.Emazweni aseYurophu naseMelika, ngaphezu kuka-50% asetshenziswa emfuyweni antidiarrheal izidakamizwa kanye izithasiselo feed.

5. Ngaphandle kwezakhiwo ezivamile zotshwala nama-ketones, iphinde ibonise umbala obomvu omnyama nge-ferric chloride futhi yakha ama-chelates anosawoti amaningi ensimbi.Nge-acetic anhydride noma i-acetyl chloride ne-acetone condensation, noma ngokusabela kwe-acetone ne-ketene etholiwe.I-Chemicalbook isetshenziswa njenge-extractant yensimbi ukuhlukanisa ama-ion a-trivalent nama-tetravalent, okomisa upende noyinki, izibulala-zinambuzane, izibulala-zinambuzane, ama-fungicides, izinyibilikisi zama-polymers aphezulu, ama-reagents ekunqumeni i-thallium, insimbi, i-fluorine, kanye ne-organic synthesis intermediates.

6. Transition metal chelators.Ukunqunywa kwe-colorimetric yensimbi ne-fluorine, nokunqunywa kwe-thallium phambi kwe-carbon disulfide.

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

8. Isetshenziswa njenge-ejenti yenguquko yensimbi ye-chelating;isetshenziselwa ukunqunywa kwe-colorimetric yensimbi ne-fluorine, nokunqunywa kwe-thallium lapho kukhona i-carbon disulfide.

9. Inkomba ye-iron (III) i-complexometric titration.Isetshenziselwa ukuguqula amaqembu e-guanidine kumaprotheni nasemaqenjini amino kumaprotheni.
