Igiciro cyiza cy'umusaruro ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

ibisobanuro bigufi:

ACETYL ACETONE, izwi kandi nka diacetylmethane, pentamethylene dione, ni ikintu gikomoka kuri acetone, formula ya molekile CH3COCH2COCH3, idafite ibara cyangwa umuhondo woroshye ubonerana. ACETYL ACETONE ubusanzwe ni uruvange rw'ibice bibiri bya tautomer, enol na ketone, biri mu buryo buhindagurika. Isomeri za Enol Chemicalbook zikora imigozi ya hydrogen muri molekile. Muri urwo ruvange, keto ingana na 18%, naho alkenes Alcohol form ingana na 82%. Umuti wa ether ya peteroli y'uruvange wakonjeshejwe kugeza kuri -78°C, maze inol form ihinduka nk'ikintu gikomeye, ku buryo byombi byatandukanye; igihe inol form yasubiraga ku bushyuhe bw'icyumba, ACETYL ACETONE yahise iba mu buryo bwavuzwe haruguru.

Imikoreshereze ya ACETYL ACETONE

1. Pentanedione, izwi kandi ku izina rya acetylacetone, ni yo ikoreshwa mu gutera imiti yica udukoko nka pyraclostrobin, azoxystrobin na rimsulfuron.

2. Ishobora gukoreshwa nk'ibikoresho fatizo n'ibikomoka ku bimera mu miti, ndetse ishobora no gukoreshwa nk'ibishongesha.

3. Ikoreshwa nk'igikoresho cyo gusesengura no gukurura aluminiyumu muri tungsten na molybdenum.

4. Asetilacetone ni igikoresho cy’ingenzi mu gukora organic synthesis, kandi ikora amino-4,6-dimethylpyrimidine hamwe na guanidine, ikaba ari igikoresho cy’ingenzi mu buvuzi. Ishobora gukoreshwa nk'umusemburo wa cellulose acetate, inyongeramusaruro ya lisansi n'amavuta, desiccant yo gusiga irangi na varnish, fungicide, n'umuti wica udukoko. Asetilacetone ishobora kandi gukoreshwa nk'umusemburo wo gucika kwa peteroli, hydrogenation na carbonylation reactions, ndetse n'umusemburo wo kwihutisha ogisijeni. Ishobora gukoreshwa mu gukuraho ogiside z'icyuma mu bintu bikomeye bifite imyenge no kuvura catalysts za polypropylene. Mu bihugu by'i Burayi na Amerika, ibirenga 50% bikoreshwa mu miti irwanya impiswi n'ibiryo by'amatungo.

5. Uretse imiterere isanzwe ya alkoholi na ketone, inagaragaza ibara ry'umutuku wijimye hamwe na ferric chloride kandi ikora chelate hamwe n'imyunyu myinshi y'icyuma. Binyuze muri acetic anhydride cyangwa acetyl chloride na acetone condensation, cyangwa binyuze mu buryo acetone na ketene byabonetse. Chemicalbook ikoreshwa nk'icyuma gikuramo iyoni mu gutandukanya iyoni za trivalenti na tetravalenti, irangi n'inki byumisha, imiti yica udukoko, imiti yica udukoko, fungicides, solvents kuri polymer nyinshi, reagents zo kumenya thallium, icyuma, fluorine, n'ibintu bihuza organic synthesis.

6. Impinduka mu byuma bipima ubushyuhe. Gupima icyuma na fluorine mu buryo bw'amabara, no kumenya thallium mu gihe hari disulfide ya karuboni.

7. Ikimenyetso cya Fe(III) complexometric titration; gikoreshwa mu guhindura amatsinda ya guanidine (nka Arg) n'amatsinda ya amine muri poroteyine.

8. Ikoreshwa nk'igikoresho cyo guhindura icyuma gipima ubushyuhe; ikoreshwa mu kumenya icyuma na fluorine mu buryo bw'amabara, no kumenya thallium mu gihe hari disulfide ya karuboni.

9. Ikimenyetso cyerekana imiterere y'icyuma (III) complexometric. Gikoreshwa mu guhindura amatsinda ya guanidine muri poroteyine n'amatsinda ya amine muri poroteyine.
