Qhov txawv ntawm acetone thiab acetate yog acetone yog ketone whereas acetate yog anion muab los ntawm acetic acid.
Ob qho tib si acetone thiab acetate tau kawm nyob rau hauv cov organic chemistry vim lawv yog cov organic tebchaw lossis cov derivatives ntawm cov organic compounds. Acetone yog qhov yooj yim tshaj plaws ntawm tsev neeg ketone thaum acetate yog anion tsim los ntawm acetic acid.
Acetone yog dab tsi?
Acetone yog ketone uas muaj cov tshuaj formula (CH3)2CO. Nws tshwm sim raws li cov xim tsis muaj xim, flammable thiab volatile kua nyob rau hauv chav tsev kub. Nws yog qhov yooj yim tshaj plaws, yog li, qhov tsawg tshaj plaws ketone hauv tsev neeg ketone. Tsis tas li ntawd, nws yog ib qho organic hnyav peb siv nyob rau hauv ob qho tib si tsev neeg thiab kev lag luam xav tau. Tsis tas li, nws yog ib qho khoom muaj nyob rau hauv cov ntsia thawv polish tshem tawm, kua roj vanish, kua nplaum, roj hmab cement, thiab lwm yam.
Txoj kev tam sim no ntawm acetone ntau lawm yog los ntawm propylene. Peb hu txoj kev no cov txheej txheem cumene. Nws koom nrog benzene reacting nrog propylene (alkylation ntawm benzene), muab cumene, uas yog ib qho organic compound raws li ib tug aromatic hydrocarbon nrog ib tug aliphatic hloov. Los ntawm oxidation ntawm cumene, peb tuaj yeem tau txais phenol thiab acetone. Cov tshuaj tiv thaiv yog raws li nram no:
Daim duab 01: Cov txheej txheem tsim khoom Acetone
Daim ntawv thov tseem ceeb ntawm acetone yog qhov hnyav. Nws yog ib qho hnyav hnyav rau plastics thiab hluavtaws fibers. Ntxiv mus, acetone muaj txiaj ntsig zoo li cov khoom siv raw rau kev sib txuas ntawm methyl methacrylate. Tsis tas li ntawd, nws muaj txiaj ntsig zoo li khoom noj khoom haus ntxiv.
Acetate yog dab tsi?
Acetate yog cov anion muab los ntawm acetic acid. Cov tshuaj formula ntawm anion yog CH3COO-. Peb tuaj yeem sau nws li OAc. Piv txwv li, peb tuaj yeem sau luv sodium acetate li NaOAc. Yog tias cov anion ua ke nrog hydrogen cation, ces nws tsim acetic acid (carboxylic acid). Yog hais tias cov acetate ion ua ke nrog ib pawg alkyl, nws tsim ib qho ester.
Daim duab 2: Cov qauv ntawm Acetate Ion
Feem ntau, peb siv lo lus acetate rau npe ntsev ntawm acetic acid. Cov ntsev no muaj kev sib xyaw ntawm acetic acid nrog alkaline, earthy, metallic lossis nonmetallic thiab lwm lub hauv paus. Ntxiv mus, lo lus no muaj nyob rau hauv biology raws li lub ntsiab compound siv los ntawm cov kab mob nyob, 'acetyl CoA'.
Qhov txawv ntawm Acetone thiab Acetate yog dab tsi?
Acetone yog ketone nrog cov tshuaj formula (CH3)2CO thaum acetate yog anion. Qhov sib txawv tseem ceeb ntawm acetone thiab acetate yog acetone yog ketone thaum acetate yog anion peb muab los ntawm acetic acid. Acetone yog ib qho nruab nrab nruab nrab thaum acetate muaj - 1 nqi.
Tsis tas li ntawd, peb tuaj yeem tsim acetone artificially los ntawm cov txheej txheem cumene, tab sis biologically, nws tsim nyob rau hauv peb lub cev thaum lub sij hawm cov rog tawg mus rau hauv ketone lub cev. Whereas, acetate cov ntaub ntawv los ntawm kev tshem tawm cov proton los ntawm acetic acid.
Cov ntaub ntawv hauv qab no-daim duab qhia txog qhov sib txawv ntawm acetone thiab acetate hauv daim ntawv tabular.
Summary – Acetone vs Acetate
Acetone yog cov organic compound thaum acetate yog anion muab los ntawm acetic acid (carboxylic acid). Qhov sib txawv tseem ceeb ntawm acetone thiab acetate yog acetone yog ketone whereas acetate yog anion muab los ntawm acetic acid.
