Propanol yog ib hom cawv uas muaj peb carbon atoms hauv nws cov qauv molecular. Txawm li cas los xij, muaj ob hom propanol sib txawv, nyob ntawm qhov chaw ntawm hydroxyl (-OH) pawg ntawm cov saw hlau. Cov ntaub ntawv no yog hu ua 1-propanol thiab 2-propanol, thiab lawv muaj cov khoom sib txawv thiab siv. Hauv tsab xov xwm no, peb yuav piav qhia yuav ua li cas kom paub qhov txawv ntawm 1-propanol thiab 2-propanol siv qee qhov kev sim tshuaj yooj yim.
Cov qauv thiab kev faib tawm ntawm Propanols
Qhov sib txawv tseem ceeb ntawm 1-propanol thiab 2-propanol yog qhov chaw ntawm pawg hydroxyl ntawm cov pob txha carbon. Nyob rau hauv 1-propanol, pawg hydroxyl txuas rau lub davhlau ya nyob twg carbon atom, uas yog nyob rau ntawm qhov kawg ntawm cov saw hlau. Hauv 2-propanol, pawg hydroxyl txuas nrog nruab nrab carbon atom, uas tsis yog qhov kawg ntawm cov saw hlau. Qhov sib txawv ntawm cov qauv no cuam tshuam rau kev faib tawm ntawm propanols ua thawj lossis theem nrab cawv.
Ib qho cawv tseem ceeb yog ib qho cawv uas muaj pawg hydroxyl txuas rau lub davhlau ya nyob twg carbon atom, uas tsuas muaj ib qho ntawm lwm cov pa roj carbon atom txuas rau nws. Ib qho cawv thib ob yog ib qho cawv uas muaj pawg hydroxyl txuas nrog rau qhov tsis yog -terminal carbon atom, uas muaj ob lwm carbon atoms sib txuas rau nws. Yog li, 1-propanol yog thawj cawv thiab 2-propanol yog cawv thib ob.
Daim ntawv thov sib txawv
Propan-1-olFeem ntau yog siv los tsim cov tshuaj xws li propane, propylene, thiab dimethyl carbonate, thaum Propan-2-ol yog siv dav hauv kev tsim cov polyethers, coatings, thiab lwm yam kev siv.
