Mtengo Wabwino Wopanga ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

kufotokozera mwachidule:

ACETYL ACETONE, yomwe imadziwikanso kuti diacetylmethane, pentamethylene dione, ndi yochokera ku acetone, molecular formula CH3COCH2COCH3, yopanda utoto kapena yachikasu yowala yowonekera. ACETYL ACETONE nthawi zambiri imakhala chisakanizo cha ma tautomers awiri, enol ndi ketone, omwe ali mu dynamic equilibrium. Ma isomers a Enol Chemicalbook amapanga ma hydrogen bond mu molekyulu. Mu chisakanizocho, keto imakhala pafupifupi 18%, ndipo alkenes Alcohol form imakhala 82%. Yankho la petroleum ether la chisakanizocho linaziziritsidwa mpaka -78°C, ndipo mawonekedwe a enol adasinthidwa kukhala olimba, kotero kuti awiriwa adalekanitsidwa; pamene mawonekedwe a enol adabwerera kutentha kwa chipinda, ACETYL ACETONE idakhala yokha mu mkhalidwe wofanana ndi womwe uli pamwambapa.

Kugwiritsa ntchito kwa 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.
