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

Kufotokozera mwachidule:

ACETYL ACETONE, yomwe imadziwikanso kuti diacetylmethane, pentamethylene dione, imachokera ku acetone, formula ya molekyulu CH3COCH2COCH3, yopanda utoto mpaka yachikasu yowonekera.ACETYL ACETONE nthawi zambiri imakhala yosakanikirana ndi ma tautomer awiri, enol ndi ketone, omwe amakhala ofanana kwambiri.Ma isomers a Enol Chemicalbook amapanga ma hydrogen bond mu molekyulu.Mu osakaniza, keto amawerengera pafupifupi 18%, ndipo alkenes Mawonekedwe a mowa amakhala 82%.Mafuta a petroleum ether yankho la osakaniza anali atakhazikika mpaka -78 ° C, ndipo mawonekedwe a enol adawombedwa ngati olimba, kotero kuti awiriwa adalekanitsidwa;mawonekedwe a enol atabwerera ku kutentha kwachipinda, ACETYL ACETONE idangokhala momwemo.

Kugwiritsa ntchito kwa 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.
