Acetylacetone,yomwe imadziwikanso kuti 2, 4-pentadione, ndi mankhwala achilengedwe, formula ya mankhwala C5H8O2, madzi owonekera opanda mtundu kapena achikasu pang'ono, osungunuka pang'ono m'madzi, ndipo ethanol, ether, chloroform, acetone, ayezi acetic acid ndi zosungunulira zina zachilengedwe zomwe zimagwiritsidwa ntchito kwambiri ngati zosungunulira, chotulutsira, chingagwiritsidwenso ntchito pokonza zowonjezera zamafuta, mafuta odzola, mankhwala ophera tizilombo, mankhwala ophera tizilombo, utoto, ndi zina zotero.
Katundu:Acetone ndi madzi opanda mtundu kapena achikasu pang'ono omwe amatha kuyaka. Kutentha kwake ndi 135-137 ° C, kuwala kwake ndi 34 ° C, ndipo kutentha kwake ndi -23 ° C. Kuchuluka kwake ndi 0.976, kuchotsera kwake ndi N20d1.4512. Acetone imasungunuka mu 8g ya madzi, ndipo imasakanizidwa ndi ethanol, benzene, chloroform, ether, acetone, ndi methampitic acid, ndipo imasungunuka kukhala acetone ndi acetic acid mu alkali solution. Ponena za kutentha kwambiri, moto wopepuka komanso oxidant wamphamvu, zimakhala zosavuta kuyambitsa kuyaka. Sizikhazikika m'madzi, zimasungunuka mosavuta kukhala acetic acid ndi acetone.
Pakati pa kapangidwe ka organic:
Acetylacetone ndi chinthu chofunikira kwambiri pakupanga zinthu zachilengedwe, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, zonunkhira, mankhwala ophera tizilombo ndi mafakitale ena.
Acetone ndi chinthu chofunikira kwambiri pamakampani opanga mankhwala, monga kupanga zinthu zotumphukira za 4,6 - dimethylpyrimidine. Imagwiritsidwanso ntchito ngati chosungunulira cha cellulose acetate, desiccant ya utoto ndi varnish, komanso reagent yofunika kwambiri yowunikira.
Chifukwa cha kukhalapo kwa mawonekedwe a enol, acetylacetone imatha kupanga ma chelates okhala ndi cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminiyamu, chromium, iron (Ⅱ), mkuwa, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium ndi thorium ndi ma ayoni ena achitsulo, omwe angagwiritsidwe ntchito ngati zowonjezera mu mafuta amafuta ndi mafuta opaka.
Buku la Chemicalbook lingagwiritsidwe ntchito ngati chotsukira zitsulo zomwe zili m'ma micropores chifukwa cha chelation yake ndi zitsulo. Limagwiritsidwa ntchito ngati chothandizira, cholumikizira resin, chothandizira kuchiritsa resin; Resin, zowonjezera za rabara; Limagwiritsidwa ntchito pa hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis ndi low carbon olefin polymerization ndi copolymerization; Limagwiritsidwa ntchito ngati organic solvent, limagwiritsidwa ntchito pa cellulose acetate, inki, pigment; Chotsukira utoto; Zipangizo zopangira mankhwala ophera tizilombo ndi fungicides, mankhwala oletsa kutsegula m'mimba ndi zowonjezera zakudya; Galasi lowunikira la infrared, filimu yowongolera yowonekera (indium salt), filimu yowongolera superconducting (indium salt) yopangira; Acetylacetone metal complex ili ndi mtundu wapadera (wobiriwira wamchere wamkuwa, wofiira wachitsulo, chromium salt purple) ndipo susungunuka m'madzi; Limagwiritsidwa ntchito ngati zopangira mankhwala; Zipangizo zopangidwa ndi organic.
Kugwiritsa Ntchito ACETYL ACETONE：
1. Pentanedione, yomwe imadziwikanso kuti acetylacetone, ndi mankhwala apakati a pyraclostrobin, azoxystrobin ndi rimsulfuron yophera tizilombo toyambitsa matenda.
2. Itha kugwiritsidwa ntchito ngati zipangizo zopangira zinthu komanso ngati zinthu zachilengedwe zopangira mankhwala, komanso ingagwiritsidwe ntchito ngati zosungunulira.
3. Amagwiritsidwa ntchito ngati chothandizira kusanthula komanso chothandizira kuchotsa aluminiyamu mu tungsten ndi molybdenum.
4. Acetylacetone ndi chinthu chapakati pa kapangidwe ka organic, ndipo imapanga amino-4,6-dimethylpyrimidine yokhala ndi guanidine, yomwe ndi chinthu chofunikira kwambiri chopangira mankhwala. Ingagwiritsidwe ntchito ngati chosungunulira cha cellulose acetate, chowonjezera cha mafuta ndi mafuta, desiccant ya utoto ndi varnish, fungicide, ndi mankhwala ophera tizilombo. Acetylacetone ingagwiritsidwenso ntchito ngati chothandizira kusweka kwa mafuta, hydrogenation ndi carbonylation reactions, komanso chothandizira okosijeni cha mpweya. Ingagwiritsidwe ntchito kuchotsa zitsulo zosungunuka mu zinthu zolimba komanso kuchiza polypropylene catalysts. M'mayiko aku Europe ndi America, opitilira 50% amagwiritsidwa ntchito mu mankhwala oletsa kutsegula m'mimba ndi zakudya zowonjezera.
5. Kuwonjezera pa makhalidwe abwino a ma alcohols ndi ma ketones, imawonetsanso mtundu wofiira wakuda ndi ferric chloride ndipo imapanga ma chelates okhala ndi mchere wambiri wachitsulo. Ndi acetic anhydride kapena acetyl chloride ndi acetone condensation, kapena ndi momwe acetone ndi ketene zimachitikira. Chemicalbook imagwiritsidwa ntchito ngati chotsitsa chachitsulo kulekanitsa ma ion a trivalent ndi tetravalent, zoumitsira utoto ndi inki, mankhwala ophera tizilombo, mankhwala ophera tizilombo, fungicides, zosungunulira ma polima ambiri, ma reagents otsimikizira thallium, iron, fluorine, ndi organic synthesis intermediates.
6. Transition metal chelators. Kuzindikira mtundu wa chitsulo ndi fluorine, ndi kudziwa thallium pamaso pa carbon disulfide.
7. Chizindikiro cha Fe(III) complexometric titration; chomwe chimagwiritsidwa ntchito posintha magulu a guanidine (monga Arg) ndi magulu a amino m'mapuloteni.
8. Amagwiritsidwa ntchito ngati chosinthira chitsulo choyezera; amagwiritsidwa ntchito poyesa colorimetric ya chitsulo ndi fluorine, komanso poyesa thallium pamaso pa carbon disulfide.
9. Chizindikiro cha titration ya chitsulo (III) complexometric. Chimagwiritsidwa ntchito kusintha magulu a guanidine m'mapuloteni ndi magulu a amino m'mapuloteni.
Mikhalidwe yosungirako:
1. Pewani Minghuo ndipo sungani oxidant wamphamvu, sungani ndikusunga.
2. Ikulungeni mu thumba la pulasitiki kapena mbiya ya pulasitiki mu mbiya yachitsulo; Mapaketi azinthu wamba: 200kg/ng'oma. Yosapsa ndi moto, yosapsa ndi moto, yosanyowa, yosungidwa m'nyumba yosungiramo zinthu zoopsa. Kusunga ndi kunyamula motsatira malamulo a mankhwala oopsa.
