Qhov sib txawv tseem ceeb ntawm isomerization thiab aromatization yog tias isomerization cuam tshuam nrog kev hloov pauv ntawm isomer mus rau lwm isomer whereas aromatization koom nrog kev hloov pauv ntawm aliphatic compound rau hauv ib qho aromatic compound.
Isomerization thiab aromatization yog qhov tseem ceeb ntawm kev sib xyaw ua ke hauv cov organic chemistry. Cov tshuaj tiv thaiv no koom nrog kev hloov pauv ntawm cov qauv tshuaj uas twb muaj lawm rau hauv cov qauv tshuaj sib txawv me ntsis. Hauv isomerization, ib daim ntawv isomeric hloov mus rau lwm daim ntawv isomeric, thaum nyob rau hauv aromatization, ib qho aliphatic compound hloov mus rau hauv ib qho aromatic compound.
Isomerization yog dab tsi?
Isomerization yog ib hom tshuaj tiv thaiv uas ib hom isomeric ntawm cov organic compound hloov mus rau lwm daim isomeric. Cov tshuaj lom neeg feem ntau tsuas muaj ib qho isomer xwb; Yog li, isomerization ntawm cov tebchaw no hais txog kev hloov pauv ntawm nws cov qauv rau hauv nws daim ntawv isomeric. Txawm li cas los xij, qee cov tshuaj lom neeg muaj ntau tshaj ib daim ntawv isomeric; Tom qab ntawd, isomerization hais txog kev hloov pauv ntawm ib daim ntawv isomeric rau hauv ib qho ntawm nws lwm hom isomeric. Cov khoom tsim tshiab (lossis daim ntawv isomeric tshiab) cov ntaub ntawv nrog tib cov tshuaj muaj pes tsawg leeg tab sis sib txawv atomic connectivity lossis configuration.
Daim duab 01: Piv txwv ntawm Isomerization (Kev hloov pauv ntawm n-Pentane rau Isopentane)
Piv txwv li, kev hloov pauv ntawm butane rau hauv isobutene yog cov tshuaj tiv thaiv ntawm isomerization. Nyob rau hauv cov tshuaj tiv thaiv no, butane yog ib tug ncaj-chain hydrocarbon qauv. Txawm li cas los xij, isobutene yog cov qauv tsim. Peb tuaj yeem ua tiav qhov isomerization ntawm kev kho cua sov ntawm butane (txog 100 degrees Celsius). Qhov kev kho cua sov no yog ua tiav nyob rau hauv lub xub ntiag ntawm ib tug haum catalyst. Ntawm no, atomic connectivity ntawm cov tshuaj compound hloov. Yog li ntawd, cov tshuaj thiab lub cev lub cev ntawm cov tshuaj lom neeg kuj hloov.
Hauv alkenes, feem ntau hom isomerization yog cis-trans isomerization. Hauv cov txheej txheem no, kev sib txuas ntawm atomic tsis hloov ntau npaum li cas vim tias thaum cis isomer hloov mus rau hauv trans isomer, tsuas yog cov pab pawg hloov pauv txuas rau ob daim ntawv cog lus hloov pauv. Ntxiv rau qhov no, peb tuaj yeem soj ntsuam cov txheej txheem isomerization ntawm cov tshuaj inorganic thiab. Nyob rau hauv cov txheej txheem no, lub isomerization ntawm kev hloov hlau complexes yog cov feem ntau daim ntawv.
Aromatization yog dab tsi?
Aromatization yog cov txheej txheem tshuaj uas ib zaug uas tsis yog tus neeg ua ntej hloov mus rau hauv cov tshuaj tsw qab. Feem ntau, peb tuaj yeem ua tiav aromatization ntawm dehydrogenation ntawm cov khoom siv cyclic uas twb muaj lawm; Piv txwv li, kev hloov pauv ntawm cyclohexane rau benzene. Ntawm no, cov ntaub ntawv sib xyaw heterocyclic.
Daim duab 02: Aromatization
Ib qho piv txwv rau aromatization hauv roj refining yog dehydrogenation ntawm naphthene. Cov tshuaj tiv thaiv no yog catalyzed los ntawm platinum, thiab nyob rau hauv cov tshuaj tiv thaiv no, naphthene hloov mus rau hauv toluene, uas yog ib qho aromatic compound.
Qhov txawv ntawm Isomerization thiab Aromatization yog dab tsi?
Isomerization thiab aromatization yog qhov tseem ceeb ntawm kev sib xyaw ua ke hauv cov organic chemistry. Qhov sib txawv tseem ceeb ntawm isomerization thiab aromatization yog tias isomerization cuam tshuam nrog kev hloov pauv ntawm isomer mus rau lwm isomer whereas aromatization koom nrog kev hloov pauv ntawm ib qho aliphatic compound rau hauv cov tshuaj tsw qab. Ib qho piv txwv ntawm isomerization yog kev hloov pauv ntawm butane rau hauv isobutene thaum hloov ntawm cyclohexane rau hauv benzene yog ib qho piv txwv rau aromatization.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm isomerization thiab aromatization.
Summary – Isomerization vs Aromatization
Ib cov ntsiab lus, isomerization thiab aromatization yog qhov tseem ceeb ntawm kev sib xyaw ua ke hauv cov organic chemistry. Qhov sib txawv tseem ceeb ntawm isomerization thiab aromatization yog tias isomerization cuam tshuam nrog kev hloov pauv ntawm isomer mus rau lwm isomer whereas aromatization koom nrog kev hloov pauv ntawm aliphatic compound rau hauv ib qho aromatic compound.
