Chaw tsim tshuaj paus zoo tus nqi acetyl acetone (2,4 pentanedione) CAS 123-54-6

Cov lus piav qhia luv luv:

Acetyl Acetone, tseem hu ua Diacetylramethane, Pentamethylene Dione, yog qhov kev ua yeeb yam ntawm acetone, molecular tus qauv ch3cochococh3, tsis muaj xim daj pob tshab. Acetyl acetone feem ntau yog kev sib xyaw ntawm ob lub sij hawm, enol thiab ketone, uas yog nyob rau hauv rynamic sib npaug. Enol Lockus Isomers Ua Hydrogen Bonds nyob rau hauv lub lwg me me. Hauv qhov sib tov, Keto cov nyiaj tau rau txog 18%, thiab alkenes Chocolate Form account rau 82%. Cov roj av roj ether ether ntawm cov sib tov yog txias rau -78 ° C, thiab EMOL daim ntawv tau ua ntej yog ib qho khoom siv, kom ob tug tau sib cais; Thaum cov ntawv tshaj tawm rov qab mus rau chav tsev kub, acetyl acetone tau cia li nyob rau hauv qhov kev sib txheeb saum toj no equilibrium.

Cov ntawv thov ntawm Acetyl Acetone

1. Pentanedione, tseem hu ua acetylacetone, yog qhov nruab nrab ntawm fungictrobin, azoxystrobin thiab cov tshuaj tua kab mob rimsulfuron.

2. Nws tuaj yeem siv los ua cov ntaub ntawv raw thiab cov organic intermediates rau cov tshuaj, thiab tseem siv tau ua cov kuab tshuaj.

3. Siv los ua kev ntsuas tshuaj thiab rho tawm tus neeg sawv cev ntawm txhuas hauv tungsten thiab molybdenum.

4. Acetylacetone is an intermediate in organic synthesis, and it forms amino-4,6-dimethylpyrimidine with guanidine, which is an important pharmaceutical raw material. Nws tuaj yeem siv los ua cov kuab tshuaj rau cov roj av thiab roj nplua nyeem thiab roj nplua nyeem thiab cov kua roj kua roj vuas, thiab tshuaj tua kab, thiab tshuaj tua kab. Acetylacetone kuj tseem siv tau ua portalyst rau roj av tawg, hydrogenation thiab carbonylation tshua, thiab oxidation nrawm rau oxygen. Nws tuaj yeem siv los tshem tawm cov hlau oxides hauv cov khib nyiab ntxig thiab los kho cov polypropylene catalysts. Hauv European thiab Asmeskas lub teb chaws, ntau tshaj 50% yog siv nyob rau hauv cov tsiaj txhu antidiarpyrhodheal tshuaj thiab pub tshuaj ntxiv.

5. Ntxiv rau cov khoom siv ntawm cov cawv thiab cov khoom Ketones, nws tseem ua rau pom cov xim liab liab liab nrog ntau cov ntsev hlau. Los ntawm acetic anhydride lossis acetyl chloride thiab acetone hws, lossis los ntawm cov tshuaj tiv thaiv ntawm acetone thiab ketene tau txais. Chemicalbook is used as metal extractant to separate trivalent and tetravalent ions, paint and ink driers, pesticides, pesticides, fungicides, solvents for high polymers, reagents for the determination of thallium, iron, fluorine, and organic synthesis intermediates.

6. Kev hloov pauv cov neeg hlau. Colorimetric txiav txim siab ntawm cov hlau thiab cov tshuaj fluorine, thiab kev txiav txim siab ntawm qhov weballium nyob rau hauv muaj cov carbon disulfide.

7. Fe (iii) cov txheej txheem ua hauj lwm qhia txog lub lim tiam no; Siv rau kev hloov kho ntawm cov pab pawg guanidine (xws li arg) thiab cov amino pawg hauv cov protein.

8. Siv ua cov neeg saib xyuas cov hlau chelating; Siv rau kev txiav txim siab Colorimetric txiav txim siab ntawm cov hlau thiab cov tshuaj fluorine, thiab kev txiav txim siab ntawm kev txiav txim siab hauv lub xub ntiag ntawm cov carbon disulfide.

9. Qhov taw qhia rau cov hlau (III) cov khoom sib dhos. Siv los hloov Guanidine pawg hauv cov protein thiab cov pab pawg amino hauv cov protein.
