I-ACETYL ACETONE(2,4 PENTANEDIONE)

I-Acetylacetone,eyaziwa nangokuthi i-2, i-4-pentadione, iyinhlanganisela yezinto eziphilayo, ifomula yamakhemikhali i-C5H8O2, uketshezi olucacile olungenambala kuya kophuzi kancane, oluncibilikayo kancane emanzini, kanye ne-ethanol, i-ether, i-chloroform, i-acetone, i-ice acetic acid nezinye izinto eziphilayo ezixutshwayo, ezisetshenziswa kakhulu njenge-solvent, i-ejenti yokukhipha, zingasetshenziswa futhi ekulungiseleleni izithasiselo zikaphethiloli, izinto zokugcoba, izibulala-zinambuzane zesikhunta, izibulala-zinambuzane, udayi, njll.

Izakhiwo:I-Acetone ayilona umbala noma iphuzi kancane elivutha kalula. Iphuzu lokubila lingu-135-137 ° C, iphuzu lokusha lingu-34 ° C, kanti iphuzu lokuncibilika lingu-23 ° C. Ubuningi obuhlobene bungu-0.976, izinga lesaphulelo lingu-N20d1.4512. I-acetone iyancibilika ku-8g wamanzi, futhi ixutshwe ne-ethanol, i-benzene, i-chloroform, i-ether, i-acetone, kanye ne-methampitic acid, futhi ibola ibe yi-acetone kanye ne-acetic acid esixazululweni se-alkali. Uma kukhulunywa ngomkhuhlane omkhulu, umlilo okhanyayo kanye ne-oxidant enamandla, kulula ukubangela ukusha. Ayizinzile emanzini, i-hydrolyzed kalula ibe yi-acetic acid kanye ne-acetone.

Okuphakathi kokwenziwa kwezinto eziphilayo:

I-Acetylacetone iyinto ebalulekile ekwakhiweni kwezinto eziphilayo, esetshenziswa kabanzi kwezemithi, amakha, izibulala-zinambuzane kanye neminye imboni.

I-Acetone iyinto ebalulekile yokusetshenziswa embonini yezemithi, njengokwenziwa kwe-4,6 - dimethylpyrimidine derivatives. Iphinde isetshenziswe njenge-solvent ye-cellulose acetate, i-desiccant yopende nama-varnish, kanye ne-reagent ebalulekile yokuhlaziya.

Ngenxa yokuba khona kwesimo se-enol, i-acetylacetone ingakha ama-chelates ane-cobalt (Ⅱ), i-cobalt (Ⅲ), i-beryllium, i-aluminium, i-chromium, i-iron (Ⅱ), ithusi, i-nickel, i-palladium, i-zinc, i-indium, i-tin, i-zirconium, i-magnesium, i-manganese, i-scandium kanye ne-thorium kanye nezinye i-ion zensimbi, ezingasetshenziswa njengezithasiselo ku-fuel oil kanye namafutha okugcoba.

I-Chemicalbook ingasetshenziswa njenge-ejenti yokuhlanza izinsimbi ezisema-micropores ngokuchelation kwayo nezinsimbi. Isetshenziswa njenge-catalyst, i-resin crosslinking agent, i-resin curing accelerator; I-Resin, izithasiselo zerabha; Isetshenziselwa ukusabela kwe-hydroxylation, ukusabela kwe-hydrogenation, ukusabela kwe-isomerization, ukwakheka kwe-ketone okungaphansi kwama-molecule kanye ne-low carbon olefin polymerization kanye ne-copolymerization; Isetshenziswa njenge-organic solvent, esetshenziselwa i-cellulose acetate, uyinki, i-pigment; I-ejenti yokomisa upende; Izinto zokusetshenziswa zokulungiselela izibulala-zinambuzane kanye ne-fungicides, izidakamizwa zokulwa nohudo lwezilwane kanye nezithasiselo zokudla; ​​Ingilazi yokubonisa ye-infrared, ifilimu ekhanyayo ekhanyayo (usawoti we-indium), i-ejenti yokwakha i-superconducting (usawoti we-indium); I-Acetylacetone metal complex inombala okhethekile (usawoti wethusi oluhlaza, usawoti wensimbi obomvu, usawoti we-chromium onsomi) futhi ayincibiliki emanzini; Isetshenziswa njengezinto zokusetshenziswa zokwelapha; Izinto zokwenziwa ze-organic.

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.

Izimo zokugcina:

1. Hlala kude ne-Minghuo futhi uvikele i-oxidant enamandla, vala bese wonga.

2. Yisonge esikhwameni sepulasitiki noma ebhodleleni lepulasitiki emgqonyeni wensimbi; Ukupakisha komkhiqizo ojwayelekile: 200kg/isigubhu. Ayishisi, ayishisi, ayibi nomswakama, igcinwe endaweni yokugcina impahla eyingozi. Isitoreji kanye nokuthuthwa ngokwemithetho yamakhemikhali ayingozi.
