Qhov sib txawv tseem ceeb ntawm 1 propanol thiab 2 propanol yog tias 1 propanol muaj nws pawg hydroxyl txuas mus rau qhov kawg ntawm cov saw hlau hos 2 propanol muaj pawg hydroxyl txuas rau nruab nrab carbon atom ntawm cov saw hlau.
Ob leeg 1 propanol thiab 2 propanol yog ob hom isomeric ntawm propanol molecule. Propanol yog ib qho cawv uas muaj peb cov pa roj carbon atom hauv cov qauv ntawm cov saw hlau, thiab muaj ib pab pawg hydroxyl (-OH) raws li pawg ua haujlwm ntawm cov molecule. Tsis tas li ntawd, qhov sib txawv ntawm 1 propanol thiab 2 propanol yog qhov chaw uas pawg hydroxyl txuas nrog rau cov saw hlau.
1 Propanol yog dab tsi?
1 propanol yog cov organic compound uas muaj cov tshuaj formula C3H8O. Nws yog thawj cawv vim nws muaj cov pab pawg hydroxyl txuas nrog cov pa roj carbon atom kawg ntawm cov saw hlau. Txij li cov pa roj carbon atom no tsuas muaj ib qho ntawm lwm cov pa roj carbon atom txuas rau nws, cov compound yog cov cawv thawj. Ntxiv mus, nws yog ib qho isomer ntawm 2 propanol.

Ib txwm, qhov sib xyaw no yog tsim nyob rau hauv ntau cov txheej txheem fermentation hauv me me. Qhov hnyav ntawm molar yog 60.09 g / mol. Tsis tas li ntawd, nws zoo nkaus li cov kua uas tsis muaj xim, muaj xim me me, muaj ntxhiab tsw ntxhiab. Tsis tas li ntawd, qhov sib xyaw no yog qhov tseem ceeb ua cov kuab tshuaj hauv kev lag luam kws tshuaj. Nws kuj tseem haum raws li lub cav roj vim muaj tus lej octane siab.
2 Propanol yog dab tsi?
2 propanol yog cov organic compound uas muaj cov tshuaj formula C3H8O, thiab nws yog ib qho isomer ntawm 1 propanol. Raws li lub npe nrov, peb hu nws isopropyl cawv. Nws tshwm sim raws li cov kua tsis muaj xim thiab flammable. Tsis tas li ntawd, nws muaj ntxhiab tsw muaj zog. Cov pab pawg hydroxyl hauv qhov sib xyaw no yog txuas rau nruab nrab carbon atom ntawm cov saw hlau. Yog li, nws yog ib qho cawv thib ob. Tsis tas li ntawd, nws yog tus qauv isomer ntawm 1 propanol.

Ntxiv mus, cov tshuaj no yog miscible nrog dej, ethanol, ether thiab chloroform. Nrog rau qhov kub thiab txias, qhov viscosity ntawm cov kua no nce siab heev. Nws tuaj yeem raug oxidation los tsim acetone. Tsis tas li ntawd, txoj kev tsim khoom loj ntawm 2 propanol yog dej tsis ncaj; Cov tshuaj tiv thaiv ntawm propene nrog sulfuric acid tsim ib qho kev sib xyaw ntawm sulfate esters, thiab tom qab hydrolysis ntawm cov esters muab isopropyl cawv.
Hais txog kev siv tau, nws muaj txiaj ntsig zoo li cov kuab tshuaj kom yaj ntau yam tsis muaj polar compounds. Piv txwv li: ntxuav cov tsom iav qhov muag, cov khoom siv hluav taws xob, thiab lwm yam. Nws tseem yog ib qho tseem ceeb ua cov tshuaj nruab nrab hauv kev tsim cov isopropyl acetate. Ntxiv mus, kev tsim cov kua dej cawv los ntawm isopropyl cawv yog qhov tseem ceeb hauv kev siv tshuaj.
Qhov txawv ntawm 1 Propanol thiab 2 Propanol yog dab tsi?
1 propanol yog cov organic compound uas muaj cov tshuaj formula C3H8O hos 2 propanol yog cov organic compound uas muaj cov tshuaj formula. C3H8O thiab nws yog ib qho isomer ntawm 1 propanol. Yog li, qhov sib txawv tseem ceeb ntawm 1 propanol thiab 2 propanol yog tias 1 propanol muaj nws pawg hydroxyl txuas rau qhov kawg ntawm cov pa roj carbon chai thaum 2 propanol muaj pawg hydroxyl txuas rau nruab nrab carbon atom ntawm cov saw hlau.
Cov duab hauv qab no qhia ntau qhov tseeb ntawm qhov sib txawv ntawm 1 propanol thiab 2 propanol.
Summary – 1 Propanol vs 2 Propanol
1 propanol yog cov organic compound uas muaj cov tshuaj formula C3H8O hos 2 propanol yog cov organic compound uas muaj cov tshuaj formula. C3H8O thiab nws yog n isomer ntawm 1 propanol. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm 1 propanol thiab 2 propanol yog tias 1 propanol muaj nws pawg hydroxyl txuas mus rau qhov kawg ntawm cov pa roj carbon chai thaum 2 propanol muaj pawg hydroxyl txuas rau nruab nrab carbon atom ntawm cov saw hlau.
