IsoPropanolThiab acetone yog ob hom organic uas muaj cov khoom zoo sib xws tab sis cov qauv txheej txheem molecular. Yog li ntawd, lo lus teb rau lo lus nug "IsoPropanol tib yam li acetone?" yog kom meej meej tsis muaj. Kab lus no yuav txheeb xyuas qhov sib txawv ntawm isopropanol thiab acetone hais txog cov qauv molecular, cov khoom siv lub cev, tshuaj lom neeg, thiab cov khoom siv tshuaj ntxuav tes.

Ua ntej tshaj plaws, cia saib ntawm cov qauv molecular ntawm isopropanol thiab acetone. IsoPropanol (CH3CHOHCH3) muaj cov mis molecular ntawm c3h8o, thaum acetone (ch3coch3) muaj molecular cov mis ntawm c3h6o. Nws tuaj yeem pom los ntawm cov qauv molecular uas isopropanol muaj ob pawg methyl ntawm txhua sab ntawm cov pab pawg hydroxyl, thaum acetone tsis muaj pawg methyl ntawm lub carbonyl pupbon atom.

Tom ntej no, cia saib ntawm lub cev lub cev ntawm isopropanol thiab acetone. Isopropanol yog cov kua tsis muaj kob nrog lub boiling point ntawm 80-85 ° C thiab ib qho chaw khov ntawm -124 ° C. Nws yog insoluble hauv dej tab sis soluble hauv cov kuab tshuaj organic. Acetone kuj yog cov kua tsis muaj kob nrog lub rwj ntawm 56-58 ° C thiab ib qho chaw khov ntawm -103 ° C. Nws yog miscible nrog dej tab sis soluble hauv cov kuab tshuaj organic. Nws tuaj yeem pom tau tias qhov cub kub thiab khov taw tes ntawm isopropanol yog siab dua li cov acetone, tab sis lawv solubility hauv dej sib txawv.

Thib peb, cia saib ntawm cov tshuaj lom neeg ntawm isopropanol thiab acetone. IsoPropanol yog dej cawv nrog cov pab pawg hydroxyl (-h) ua pab pawg ua haujlwm. Nws tuaj yeem hnov ​​cov kua qaub los ua cov ntsev thiab koom nrog kev hloov pauv ntawm cov lus sib txuas lus halogen. Tsis tas li ntawd, isopropanol tseem tuaj yeem ua kom lub cev qhuav dej los tsim khoom tshwm sim. Acetone yog Ketone compound nrog CarbonyL Pab Pawg (-c = o) ua pab pawg ua haujlwm. Nws tuaj yeem hnov ​​cov kua qaub rau cov ntawv ESTORS thiab koom nrog ntxiv nrog aldehydes lossis ketones. Tsis tas li ntawd, acetone kuj tseem tuaj yeem ua polymerized los tsim polystyrene. Nws tuaj yeem pom tau tias lawv cov tshuaj lom neeg muaj ntau yam tshuaj sib txawv, tab sis lawv muaj lawv tus kheej cov yam ntxwv hauv cov tshuaj lom neeg.

Thaum kawg, cia peb saib ntawm daim ntawv thov ntawm isopropanol thiab acetone. IsoPropanol tau siv dav hauv cov tshuaj, tshuaj tua kab, tshuaj tua kab, cov khoom siv ua haujlwm, nws feem ntau siv los ua cov tshuaj lom neeg rau kev rho tawm thiab cais cov khoom txau. Ib qho ntxiv, nws tseem siv rau kev sib txuas ntawm lwm cov ocegic tebchaw thiab polymers. Acetone feem ntau yog siv rau kev tsim cov khoom sib txuas thiab cov khoom siv polystyrene cob, yog li nws tau ua rau cov roj hmab, pleev xim rau, acetone tuaj yeem Kuj siv ua cov hom phiaj dav dav rau kev rho tawm thiab cais cov khoom txau ntuj.

Hauv cov ntsiab lus, txawm hais tias isopropanol thiab acetone muaj qee qhov zoo sib xws hauv cov duab thiab cov qauv molecular thiab tshuaj lom neeg sib txawv. Yog li ntawd, peb yuav tsum nkag siab txog lawv qhov sib txawv hauv kev txiav txim kom siv tau zoo dua thiab tshawb fawb.
