Qhov sib txawv tseem ceeb ntawm diethyl ether thiab ethyl acetate yog tias diethyl ether muaj ntxhiab tsw zoo li rum, whereas ethyl acetate muaj ether zoo li txiv hmab txiv ntoo tsw.
Diethyl ether thiab ethyl acetate yog cov organic tebchaw tseem ceeb. Lawv muaj ntau daim ntawv thov hauv kev lag luam sib txawv thiab hauv chav kuaj, feem ntau yog cov kuab tshuaj.
Diethyl Ether yog dab tsi?
Diethyl ether yog cov organic compound nrog cov tshuaj formula C2H5OC2H5. Cov khoom no yog ib qho ether nrog ob pawg ethyl txuas rau tib lub hauv paus oxygen atom. Diethyl ether yog cov kua xim tsis muaj xim uas muaj qhov kub thiab txias heev. Tsis tas li ntawd, nws muaj rum-zoo li, qab zib tsw. Cov kua no muaj txiaj ntsig zoo raws li cov kuab tshuaj, tshuaj loog, thiab tshuaj lom neeg vim nws tsis muaj tshuaj lom.
Daim duab 01: Cov Qauv Tshuaj ntawm Diethyl Ether
Diethyl ether yog ib pawg ua haujlwm isomer ntawm butanol. Hauv lwm lo lus, ob qho tib si diethyl ether thiab butanol muaj tib cov tshuaj formula, tab sis diethyl ether muaj ether ua haujlwm pab pawg thaum butanol muaj cov dej cawv ua haujlwm.
Thaum xav txog kev tsim cov khoom noj khoom haus, nws feem ntau yog tsim los ntawm cov khoom siv dej ntawm ethylene thaum lub sij hawm tsim cov ethanol. Ntxiv mus, peb tuaj yeem npaj diethyl ether ntawm acid ether synthesis. Hauv cov txheej txheem no, peb yuav tsum sib tov ethanol nrog cov kua qaub sulfuric acid.
Muaj ntau yam siv tau zoo ntawm diethyl ether. Piv txwv li, nws yog ib qho tseem ceeb raws li cov kuab tshuaj nyob rau hauv lub chaw soj nstuam, raws li ib tug roj los yog ib tug pib kua, raws li ib tug general anaesthetic, thiab raws li ib feem ntawm cov tshuaj formulations. Txawm li cas los xij, txawm tias siv ntau qhov sib xyaw ua ke, nws yog qhov tsis tshua muaj hluav taws xob thiab tawg. Cov kua no kuj rhiab rau lub teeb thiab cua; Nws nyiam tsim cov peroxides tawg thaum tawg rau lub teeb thiab cua.
YEthyl Acetate yog dab tsi?
Ethyl acetate yog cov organic compound nrog cov tshuaj formula CH3CH2COOCH3. Cov molar loj ntawm cov tshuaj no yog 88 g / mol. Peb tuaj yeem categorize cov khoom no ua carboxylate ester vim ethyl acetate cov ntaub ntawv los ntawm kev sib cuam tshuam ntawm pawg carboxylate thiab ib pawg ethyl, tsim ib daim ntawv cog lus ester. Ntxiv mus, Ethyl acetate yog ester ntawm ethanol thiab acetic acid.
Daim duab 02: Cov Qauv Tshuaj ntawm Ethyl Acetate
Nyob rau hauv chav tsev kub, ethyl acetate yog cov kua tsis muaj xim nrog cov ntxhiab tsw qab. Cov kua no kuj tau siv dav los ua cov kuab tshuaj. Ethyl acetate vapor yog hnyav dua li huab cua. Muaj ntau yam kev siv rau cov kua no vim nws tus nqi qis, tsis muaj tshuaj lom, thiab tsw qab ntxiag.
Lub melting point ntawm ethyl acetate yog -83.6 ° C, thaum lub boiling point yog 77 ° C. Nws yog ib tug flammable kua thiab yog ib qho irritant. Ntxiv mus, hydrolysis ntawm Ethyl acetate ua rau acetic acid thiab ethanol. Qhov no hydrolysis yog ob-kauj ruam txheej txheem uas tshwm sim nyob rau hauv lub xub ntiag ntawm ib tug muaj zog puag xws li sodium hydroxide (NaOH). Thawj kauj ruam suav nrog kev tsim cov ethanol thiab sodium acetate, qhov thib ob kauj ruam suav nrog kev hloov pauv ntawm sodium acetate rau hauv acetic acid.
Dab tsi zoo sib xws ntawm Diethyl Ether thiab Ethyl Acetate?
- Diethyl ether thiab ethyl acetate yog cov organic compounds.
- Ob leeg yog cov tseem ceeb ua kuab tshuaj.
- Cov tshuaj no muaj ethyl functional pawg.
Qhov txawv ntawm Diethyl Ether thiab Ethyl Acetate yog dab tsi?
Diethyl ether yog cov organic compound nrog cov tshuaj formula C2H5OC2H5 thaum ethyl acetate yog cov organic compound nrog cov tshuaj formula CH3CH2COOCH3. Qhov sib txawv tseem ceeb ntawm diethyl ether thiab ethyl acetate yog tias diethyl ether muaj cov ntxhiab tsw zoo li rum, whereas ethyl acetate muaj cov ntxhiab tsw zoo li ether.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm diethyl ether thiab ethyl acetate hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Diethyl Ether vs Ethyl Acetate
Diethyl ether thiab ethyl acetate yog cov organic tebchaw tseem ceeb. Lawv muaj ntau daim ntawv thov hauv kev lag luam sib txawv thiab hauv chav kuaj, feem ntau yog cov kuab tshuaj. Qhov sib txawv tseem ceeb ntawm diethyl ether thiab ethyl acetate yog tias diethyl ether muaj cov ntxhiab tsw zoo li rum, whereas ethyl acetate muaj cov ntxhiab tsw zoo li ether.
