ACETYL ACETONE(2,4 PENTANEDIONE)

Acetylacetone, amadziwikanso kuti 2, 4-pentadione, ndi organic pawiri, mankhwala chilinganizo C5H8O2, colorless kwa pang'ono chikasu mandala madzi, pang'ono sungunuka m'madzi, ndi Mowa, efa, chloroform, acetone, ayezi asidi ndi zina organic solvents miscible, makamaka ntchito monga zosungunulira, m'zigawo wothandizira, Angagwiritsidwenso ntchito pokonza zina petulo, lubricant, nkhungu tizilombo, mankhwala, utoto, utoto, etc.

ACETYL ACETONE 1

Katundu:Acetone ndi madzi opanda mtundu kapena achikasu pang'ono omwe amatha kuyaka.Malo otentha ndi 135-137 ° C, kung'anima ndi 34 ° C, ndipo malo osungunuka ndi -23 ° C. Kuchulukana kwachibale ndi 0.976, kutsika mtengo ndi N20d1.4512.Acetone amasungunuka mu madzi 8g, ndipo amasakanikirana ndi ethanol, benzene, chloroform, ether, acetone, ndi methampitic acid, ndipo amawola kukhala acetone ndi acetic acid mu alkali solution.Pankhani ya kutentha kwambiri, moto wopepuka komanso wothira oxidant wamphamvu, ndizosavuta kuyambitsa kuyaka.Osakhazikika m'madzi, amasungunuka mosavuta kukhala acetic acid ndi acetone.

Pakatikati pa organic synthesis:

Acetylacetone ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic, yomwe imagwiritsidwa ntchito kwambiri muzamankhwala, kununkhira, mankhwala ophera tizilombo ndi mafakitale ena.

Acetone ndizofunikira kwambiri pamakampani opanga mankhwala, monga kaphatikizidwe ka 4,6 - dimethylpyrimidine zotumphukira.Amagwiritsidwanso ntchito ngati chosungunulira cha cellulose acetate, desiccant ya utoto ndi ma vanishi, komanso chinthu chofunikira chowunikira.

Chifukwa cha mawonekedwe a enol, acetylacetone imatha kupanga chelates ndi cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminium, chromium, chitsulo (Ⅱ), mkuwa, faifi tambala, palladium, zinki, indium, tini, zirconium, magnesium, manganese, scandium ndi thorium ndi ayoni zitsulo zina, zomwe zingagwiritsidwe ntchito ngati zowonjezera mu mafuta amafuta ndi mafuta opaka mafuta.

Chemicalbook itha kugwiritsidwa ntchito ngati choyeretsera zitsulo mu ma micropores ndi chelation ndi zitsulo.Amagwiritsidwa ntchito ngati chothandizira, utomoni crosslinking wothandizira, utomoni kuchiritsa accelerator;utomoni, zowonjezera mphira;Amagwiritsidwa ntchito pa hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis ndi otsika carbon olefin polymerization ndi copolymerization;Amagwiritsidwa ntchito ngati zosungunulira organic, ntchito mapadi acetate, inki, pigment;utoto kuyanika wothandizira;Zopangira zopangira mankhwala ophera tizilombo ndi fungicides, mankhwala oletsa kutsekula m'mimba ndi zina zowonjezera chakudya;Galasi yowonetsera infuraredi, filimu yowoneka bwino (mchere wa indium), filimu ya superconducting (indium salt) kupanga wothandizira;Acetylacetone zitsulo zovuta zimakhala ndi mtundu wapadera (wobiriwira wamchere wamkuwa, mchere wachitsulo wofiira, chromium mchere wofiirira) ndi wosasungunuka m'madzi;Amagwiritsidwa ntchito ngati zopangira mankhwala;Zinthu zopangidwa ndi organic.

Ntchito za ACETYL ACETONE:

1. Pentanedione, yomwe imatchedwanso acetylacetone, ndi yapakati pa fungicides pyraclostrobin, azoxystrobin ndi herbicide rimsulfuron.

2. Itha kugwiritsidwa ntchito ngati zida zopangira ndi organic intermediates kwa mankhwala, komanso ingagwiritsidwe ntchito ngati zosungunulira.

3. Amagwiritsidwa ntchito ngati reagent yowunikira komanso yotulutsa aluminiyamu mu tungsten ndi molybdenum.

4. Acetylacetone ndi yapakatikati mwa organic synthesis, ndipo imapanga amino-4,6-dimethylpyrimidine ndi guanidine, yomwe ndi yofunika kwambiri ya mankhwala.Itha kugwiritsidwa ntchito ngati chosungunulira cha cellulose acetate, chowonjezera chamafuta ndi mafuta, desiccant ya utoto ndi varnish, fungicide, ndi mankhwala ophera tizilombo.Acetylacetone ingagwiritsidwenso ntchito ngati chothandizira kuti mafuta awonongeke, hydrogenation ndi carbonylation reactions, ndi okosijeni accelerator kwa mpweya.Angagwiritsidwe ntchito kuchotsa zitsulo oxides mu zolimba porous ndi kuchiza polypropylene catalysts.M'mayiko a ku Ulaya ndi ku America, oposa 50% amagwiritsidwa ntchito ngati mankhwala oletsa kutsekula m'mimba ndi zakudya zowonjezera.

5. Kuphatikiza pa zomwe zimakhala za mowa ndi ketoni, zimasonyezanso mtundu wofiira wakuda ndi ferric chloride ndikupanga chelates ndi mchere wambiri wachitsulo.Ndi acetic anhydride kapena acetyl chloride ndi acetone condensation, kapena ndi momwe acetone ndi ketene adalandira.Chemicalbook imagwiritsidwa ntchito ngati zitsulo zopangira zitsulo zolekanitsa ma ion a trivalent ndi tetravalent, utoto ndi zowumitsira inki, mankhwala ophera tizilombo, mankhwala ophera tizilombo, ma fungicides, zosungunulira za ma polima apamwamba, ma reagents kuti athe kudziwa za thallium, chitsulo, fluorine, ndi organic synthesis intermediates.

6. Kusintha zitsulo chelators.Colorimetric kutsimikiza kwachitsulo ndi fluorine, ndi kutsimikiza kwa thallium pamaso pa carbon disulfide.

7. Fe (III) complexometric titration chizindikiro;amagwiritsidwa ntchito posintha magulu a guanidine (monga Arg) ndi magulu amino mu mapuloteni.

8. Ntchito ngati kusintha zitsulo chelating wothandizira;amagwiritsidwa ntchito pozindikira mtundu wa chitsulo ndi fluorine, komanso kutsimikiza kwa thallium pamaso pa carbon disulfide.

9. Chizindikiro chachitsulo (III) complexometric titration.Ntchito kusintha guanidine magulu mapuloteni ndi amino magulu mapuloteni.

Zosungirako:

1. Khalani kutali ndi Minghuo ndi oxidant wamphamvu, sindikizani ndikusunga.

2. Amangireni mu thumba la pulasitiki kapena mbiya ya pulasitiki mu mbiya yachitsulo;Kuyika kwa zinthu zanthawi zonse: 200kg/drum.Zosatentha, zosapsa, zosunga chinyezi, zosungidwa m'nkhokwe yowopsa.Kusungirako ndi zoyendera malinga ndi malamulo a mankhwala owopsa.
