Qhov sib txawv tseem ceeb ntawm acetone thiab isopropyl cawv yog tias acetone muaj C=O daim ntawv cog lus nyob nruab nrab ntawm cov qauv tshuaj, hos isopropyl cawv muaj C-OH pawg nyob nruab nrab ntawm cov qauv tshuaj.
Acetone thiab isopropyl cawv muaj cov qauv zoo sib xws; ob lub tebchaw no muaj peb carbon atoms ib molecule, thiab muaj kev hloov ntawm nruab nrab carbon. Cov pab pawg hloov ntawm nruab nrab carbon yog sib txawv ntawm ib leeg; acetone muaj pawg oxo thaum isopropyl cawv muaj pawg hydroxyl.
Acetone yog dab tsi?
Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3)2CO. Cov tshuaj no tshwm sim li cov kua uas tsis muaj xim thiab flammable uas yog volatile heev. Acetone yog qhov yooj yim tshaj plaws thiab tsawg tshaj plaws ntawm cov ketones. Qhov hnyav ntawm molar yog 58 g / mol. Cov tshuaj no muaj pungent, irritating tsw thiab miscible nrog dej. Acetone feem ntau yog cov kuab tshuaj polar. Qhov polarity tuaj vim qhov sib txawv ntawm electronegativity siab ntawm carbon thiab oxygen atoms ntawm carbonyl pawg. Txawm li cas los xij, nws tsis yog qhov polar heev; Yog li ntawd, acetone tuaj yeem yaj ob qho lipophilic thiab hydrophilic tshuaj.
Daim duab 01: Cov qauv tshuaj ntawm Acetone
Peb lub cev tuaj yeem tsim cov acetone hauv cov txheej txheem metabolic, thiab nws raug tshem tawm ntawm lub cev los ntawm cov txheej txheem sib txawv. Ntawm kev lag luam nplai, txoj kev tsim khoom suav nrog kev tsim khoom ncaj qha lossis tsis ncaj los ntawm propylene. Cov txheej txheem ntau yog txheej txheem cumene.
Isopropyl cawv yog dab tsi?
Isopropyl cawv lossis 2-propanol yog cawv muaj cov mis molecular C3H8O. Cov tshuaj no muaj tib lub qauv molecular li propanol. Qhov hnyav molecular yog nyob ib ncig ntawm 60 g mol -1 Yog li, peb tuaj yeem hais tias isopropyl cawv yog isomer ntawm propanol. Muaj ib pab pawg hydroxyl nyob rau hauv cov molecule no uas txuas nrog rau cov pa roj carbon thib ob hauv cov saw hlau. Qhov kev txuas no ua rau nws muaj cawv thib ob. Yog li ntawd, nws nkag mus rau tag nrho cov kev tshwm sim uas raug rau cov cawv thib ob.

Ntxiv mus, qhov melting point ntawm isopropyl cawv yog -88oC, thaum lub boiling point yog 83oC. Cov kua no yog miscible nrog dej thiab ruaj khov nyob rau hauv ib txwm muaj mob. Isopropyl cawv yog cov kua tsis muaj xim, ntshiab, thiab nplaim taws. Ntxiv mus, nws oxidizes nruj heev los tsim acetone. Thaum xav txog cov kev siv ntawm cov cawv no, nws yog ib qho tseem ceeb raws li cov kuab tshuaj thiab siv nyob rau hauv cov tshuaj, cov khoom siv hauv tsev, thiab cov khoom siv tu tus kheej. Peb kuj siv tau los ua lwm yam tshuaj.
Qhov txawv ntawm Acetone thiab Isopropyl cawv yog dab tsi?
Acetone thiab isopropyl cawv muaj cov qauv zoo sib xws; ob lub tebchaw no muaj peb carbon atoms ib molecule, thiab muaj kev hloov ntawm nruab nrab carbon. Qhov sib txawv tseem ceeb ntawm acetone thiab isopropyl cawv yog tias acetone muaj C=O daim ntawv cog lus nyob nruab nrab ntawm cov qauv tshuaj, hos isopropyl cawv muaj C-OH pawg hauv nruab nrab ntawm cov qauv tshuaj.
Cov hauv qab no infographic teev qhov sib txawv tseem ceeb ntawm acetone thiab isopropyl cawv hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Acetone vs Isopropyl Cawv
Cov pab pawg hloov ntawm nruab nrab carbon ntawm acetone thiab isopropyl cawv sib txawv ntawm ib leeg; acetone muaj pawg oxo thaum isopropyl cawv muaj pawg hydroxyl. Qhov sib txawv tseem ceeb ntawm acetone thiab isopropyl cawv yog tias acetone muaj C=O daim ntawv cog lus nyob nruab nrab ntawm cov qauv tshuaj, hos isopropyl cawv muaj C-OH pawg hauv nruab nrab ntawm cov qauv tshuaj.
