I-Acetyl Acetone (2,4 Pentanedione)

I-acetylacetone, eyaziwa nangokuthi 2, 4-Pentadione, iyingxenye ye-organic, iFomula C5h8o2, engenamibala kuya koketshezi olunombala omncane, i-ethanol, i-acetic acetic acid kanye nezinye izinsimbi eziphilayo ezingaqondakali, ikakhulukazi isetshenziswa njenge-solvent, ument we-extraction, nayo ingasetjenziswa ekuhlelweni kwezithasiselo zikaphethiloli, ama-lubricident, insecticides yokubumba, Ama-pesticides, amadayi, njll.

Izakhiwo:I-Acetone inguketshezi olungenamibala noma oluphuzi kancane. Iphuzu elibilayo lingu-135-137 ° C, i-Flash Point ingu-34 ° C, futhi iphuzu lokuncibilika lingu-23 ° C. Ubuningi obuhlobene ngu-0.976, inani lesaphulelo lingu-N20D1.4512. I-acetone iyanyibilika kuma-8g wamanzi, futhi ixubene ne-ethanol, i-benzene, i-chloroform, ether, i-acetone, ne-methampitic acid, futhi ibolile ibe yi-acetone ne-acetic acid kwikhambi le-alkali. Uma kukhulunywa ngomkhuhlane omkhulu, umlilo okhanyayo kanye ne-oxidant eqinile, kulula ukudala ukushiswa. Ingazinzile emanzini, i-hydrolyzed kalula ibe yi-acetic acid ne-acetone.

I-Intermediate ye-Organic Synthesis:

I-acetylacetone ingumphakathi obalulekile ekuhlolweni kwe-organic, esetshenziswa kabanzi ekhemisi, amakha, ama-pesticide kanye nezinye izimboni.

I-Acetone iyinto ebalulekile eluhlaza embonini yezemithi, efana nokuhlanganiswa kuka-4,6 - Dimethylpyrimidine okuvela kona. Iphinde isetshenziswe njenge-solvent ye-cellulose acetate, i-desiccant for Paints nama-varnish, kanye ne-realent ebalulekile yokuhlaziya.

Ngenxa yokuba khona kwefomu le-ENOL, i-acetylacetone ingakha ama-chelates nge-cobalt (ⅱ), i-cobalt (ⅱ), i-aluminium, i-aluminium, i-aluminium, i-palladium, i-zinc, i-indonium, i-magnesium, I-Manganese, Scandium ne-Thorium namanye ama-Ion wensimbi, angasetshenziswa njengezengezo kumafutha kaphethiloli nokuthambisa uwoyela.

I-ChemicalBook ingasetjenziswa njenge-ejenti yokuhlanza yezinsimbi ku-micropores nge-chelation yayo ngezinsimbi. Isetshenziswa njenge-catalyst, i-resin crosslinking ejenti, resin efuna ukusheshisa; Resin, izengezo zenjoloba; Isetshenziselwe ukusabela kwe-hydroxylation, ukusabela kwe-hydrogenation, ukusabela kwe-isomerization, ukuhlanganiswa okuphansi kwamangqamuzana ama-ketone kanye ne-carbon olefin ephansi ye-carbon Olefin Elefin; Isetshenziswa njenge-organic solvent, esetshenziselwa i-cellulose acetate, inki, i-pigment; Upende omisiwe; Izinto ezivuthiwe zokulungiswa kwezinambuzane kanye nama-fungicides, izidakamizwa zezilwane anatidiarrheal kanye nezithasiselo zokuphakelayo; I-infrared ekhombisa ingilazi, ifilimu ebonakalayo yefilimu (usawoti we-indis), ifilimu ebabazekayo (usawoti we-Indium) owakha i-ejenti; I-acetylacetone yensimbi eyinkimbinkimbi inombala okhethekile (i-SALTER kasawoti eluhlaza, i-iron usawoti obomvu, onsomi kasawoti we-chromium) nokungabonakali emanzini; Isetshenziswa njengezinto ezingavuthiwe zemithi; Izinto zokwenziwa ze-organic.

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.

Izimo Zokugcina:

1. Hlala kude neMinghuo ne-oxidant eqinile, uphawu bese ugcine.

2. Sisonge esikhwameni sepulasitiki noma umgqomo wepulasitiki emgqonyeni wensimbi; ukufakwa komkhiqizo okujwayelekile Ukugcinwa Nokuhamba Ngokusho kwemithethonqubo yamakhemikhali ayingozi.
