Umkhiqizi wentengo enhle ye-acetyl acetyl (2,4 pentanedione) i-CAS 123-54-6

Umkhiqizi wentengo enhle ye-acetyl acetyl (2,4 pentanedione) CAS 123-54-6 isithombe esifakiwe

Incazelo emfushane:

I-Acetyl Acetone, eyaziwa nangokuthi diacetylmethane, i-pentamethylene dione, iyona etholwa yi-acetone, ifomula ye-ch3coch2coch3, ingenamibala ukulula uketshezi olusobala olusobala. I-Acetyl Acetone imvamisa iyingxube yama-tautomers amabili, e-Enol neKetone, okukulokulingana okunamandla. Ama-Isomes ama-Isol e-ELBOOK ama-Isomers akha ama-hydrogen bond ku-molecule. Engxube, i-KETO ibala cishe ama-18%, kanye nama-alkene alcohol Alcohol Alcohol Akhawunti ka-82%. Isixazululo se-petroleum ether sengxube saphola saya ku -78 ° C, nefomu le-Enol laligcwele njengeliqinile, kangangokuba laba bobabili bahlukaniswa; Lapho ifomu le-ENOL libuya ekushiseni kwamakamelo, i-acetyl acetone yayisesimweni esilinganayo se-Equilibrium.

Ama-Synonyms: acetyl; i-acetyl2-propapone; i-acetyl-2-propanon; i-acetyl2-propapone; i-acetyl2-propanon; i-ch3coch2cone;

Case: 123-54-6

Izicelo ze-Acetyl Acetone

1. IPentanedione, eyaziwa nangokuthi i-acetylacetone, ingumphakathi wama-fungicides Pyraclostrobin, Azoxystrobin kanye ne-herbicide rimsulfuron.

2. Ingasetshenziswa njengezinto zokwenziwa eziluhlaza kanye ne-organic phakathi kwe-organic eziphakathi kwemithi, futhi nazo zingasetshenziswa njengezixazululo.

I-3. Isetshenziswa njenge-ejenti ye-realegent ye-aunorytical kanye ne-agent ye-aluminium eTungsten naseMolybdenum.

I-4. I-acetylacetone ingumuntu ophakathi nendawo ekuhlolweni kwe-organic, futhi yakha i-Amino-4,6-dimethylpylidine nge-guanidine, okuyinto ebalulekile yezemithi eluhlaza. Ingasetshenziswa njenge-solvent ye-cellulose acetate, isengezo sophethiloli kanye nezithako, i-desiccant yopende ne-varnish, i-fungicide, kanye nesinambuzane. I-acetylacetone nayo ingasetshenziswa njenge-catalyst yokuqhekeka kaphethiloli, i-hydrogenation kanye nokuphendula kwe-carbondlation, kanye ne-accelerator ye-oxidation ye-oksijini. Ingasetshenziswa ukususa ama-wetal oxides kuma-solids anama-porous kanye nokwelapha ama-polypropylene catalysts. Emazweni ase-Europe nakwaseMelika, ngaphezu kwama-50% asetshenziswa emithini ye-Livestock Antidiarrheal kanye nezengezo zokondle.

I-5 Nge-acetic anhydride noma i-acetyl chloride kanye nokuvuselelwa kwe-acetone, noma ngokusabela kwe-acetone ne-ketene etholakele. I-ChemicalBook isetshenziswa njenge-metal extractint ukwehlukanisa i-ion e-trivallent kanye ne-tetravalent, ama-pesticides, ama-pesticides, ama-fungicides, ama-solic for the allium, iron, ama-fluorine, kanye ne-organic synthesis okuphakathi.

6. Ama-Metal Metal Chelators. Ukuzimisela kombala wensimbi kanye ne-fluorine, kanye nokunqunywa kwe-thallium phambi kwe-carbon disfonfide.

7 Isetshenziselwa ukuguqulwa kwamaqembu e-guanidine (as arr) namaqembu e-Amino kumaprotheni.

8. Kusetshenziswe njenge-ejela yensimbi yensimbi yokuguqula i-ejenti; Isetshenziselwa ukuzimisela kombala wensimbi kanye ne-fluorine, kanye nokunqunywa kwe-thallium phambi kwe-carbon disfonfide.

I-9. Isikhombisi sensimbi (iii) Ukutholwa kwe-Colology. Kusetshenziselwa ukuguqula amaqembu e-Guanidine kumaprotheni namaqembu e-Amino kuma-protein.
