Qhov sib txawv tseem ceeb ntawm acetylacetone thiab acetylacetonate ion yog tias acetylacetone yog cov organic compound uas nyob rau hauv qeb 1, 3-diketone, whereas acetylacetonate ion yog anion muab los ntawm acetylacetonate organic compound.
Acetylacetone yog cov organic compound uas muaj cov tshuaj formula CH3COCH2COCH3. Acetylacetonate ion yog ib hom tshuaj tsis zoo uas tau txais los ntawm acetylacetone. Peb tuaj yeem txheeb xyuas ob hom tshuaj no raws li lawv cov nqi raug cai; acetylacetonate muaj pes tsawg tus nqi thaum acetylacetonate ion muaj -1 tus nqi tsis zoo.
Acetylacetone yog dab tsi?
Acetylacetone yog cov organic compound uas muaj cov tshuaj formula CH3COCH2COCH3. Nws tshwm sim raws li cov kua tsis muaj xim, thiab peb tuaj yeem faib cov ntsiab lus no ua 1, 3-diketone. Feem ntau, qhov sib xyaw no muaj nyob rau hauv qhov sib npaug nrog tautomer daim ntawv. Tsis tas li ntawd, acetylacetone yog lub hauv paus rau acetylacetonate anion, uas yog bidentate ligand. Tsis tas li ntawd, nws ua haujlwm ua lub tsev thaiv rau kev sib txuas ntawm heterocyclic compounds. Acetylacetone yog cov kua qaub tsis muaj zog.
Daim duab 01: Cov Qauv Tshuaj ntawm Acetyacetone
Tsis tas li ntawd, keto thiab enol tautomers ntawm acetylacetone nyiam sib koom ua ke hauv kev daws teeb meem. Nyob rau hauv daim ntawv enol, hydrogen atom yog sib koom sib npaug ntawm ob lub atoms oxygen. Peb tuaj yeem paub qhov txawv ntawm ob daim ntawv tautomeric los ntawm NMR spectroscopy, IR spectroscopy, thiab lwm yam.
Tsis tas li ntawd, qhov sib npaug tas li yog siab nyob rau hauv cov kuab tshuaj tsis muaj polar, qhov twg daim ntawv keto ua tau zoo dua hauv cov polar, hydrogen-bonding solvents, suav nrog dej. Hauv qhov sib piv, daim ntawv enol yog cov vinylogous analogue ntawm carboxylic acid.
Peb tuaj yeem npaj cov khoom sib xyaw no los ntawm kev hloov kho thermal ntawm isopropenyl acetate. Txawm li cas los xij, hauv chav kuaj, peb tuaj yeem pib qhov kev npaj no nrog acetone thiab acetic anhydride nyob rau hauv lub xub ntiag ntawm boron trifluoride catalyst.
Acetylacetonate Ion yog dab tsi?
Acetylacetonate ion yog ib hom tshuaj tsis zoo uas tau txais los ntawm acetylacetone. Tus nqi raug cai ntawm no anion yog -1. Qhov no anion tuaj yeem ua raws li bidentate ligand rau txoj kev tsim hauv kev sib koom ua ke chemistry. Muaj ob lub pa oxygen atoms nyob rau hauv no anion muaj ib leeg electron khub uas tuaj yeem pub dawb rau lub chaw tsim khoom hlau cation. Yog li, acetylacetonate anion yog qhov tseem ceeb hauv kev sib koom ua ke chemistry raws li ligand.
Vim tias acetylacetone yog cov kua qaub tsis muaj zog, nws zoo li muaj nyob hauv qhov sib npaug nrog nws lub hauv paus conjugate thiab tso tawm proton thaum nws nyob hauv cov tshuaj aqueous. Lub hauv paus conjugate ntawm cov kua qaub no yog acetylacetonate anion. Qhov no anion yog attracted los ntawm cov hlau cations vim yog qhov opposite nqi attraction rog.
Qhov txawv ntawm Acetylacetone thiab Acetylacetonate Ion yog dab tsi?
Acetylacetone yog cov organic compound uas muaj cov tshuaj formula CH3COCH2COCH3, thaum Acetylacetonate ion yog cov tshuaj tsis zoo uas tau txais los ntawm acetylacetone. Yog li ntawd, qhov sib txawv tseem ceeb ntawm acetylacetone thiab acetylacetonate ion yog tias acetylacetone yog cov organic compound uas yog nyob rau hauv qeb 1, 3-diketone, whereas acetylacetonate ion yog anion tau los ntawm acetylacetonate organic compound. Acetylacetone compound muaj pes tsawg tus nqi, thaum lub acetylacetonate ion muaj tus nqi raug cai ntawm -1.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm acetylacetone thiab acetylacetonate ion nyob rau hauv daim ntawv tabular rau ib sab sib piv.
Summary – Acetylacetone vs Acetylacetonate Ion
Acetylacetone thiab acetylacetonate ions yog cov tshuaj muaj feem xyuam vim tias acetylacetonate ion yog tsim los ntawm kev tshem tawm cov protons los ntawm acetylacetone tebchaw. Qhov sib txawv tseem ceeb ntawm acetylacetone thiab acetylacetonate ion yog tias acetylacetone yog cov organic compound uas yog nyob rau hauv qeb 1, 3-diketone, whereas acetylacetonate ion yog anion tau los ntawm acetylacetonate organic compound.
