Diethyl ether feem ntau hu ua ethyl ether , los yog txawm ntau yooj yim li xwb ether . Yog hais tias nws tau ua tib zoo qhuav ntawm tag nrho cov ya raws thiab raug xa mus rau raws li tsis muaj dej . Diethyl ether yog qhov tseem ceeb ntawm keeb kwm hauv kev tshuaj loog. Xyoo 1842, nws tau siv rau pej xeem thawj zaug rau tus neeg mob uas tau phais caj dab.
Tsis tas li ntawd, vim li cas peb thiaj siv anhydrous diethyl ether?
Rau ntau yam laj thawj, anhydrous diethyl ether yog Qhov hnyav ntawm kev xaiv rau kev ua tiav Grignard synthesis. Vapors los ntawm cov kuab tshuaj hnyav heev pab tiv thaiv cov pa oxygen kom tsis txhob ncav cuag cov tshuaj tiv thaiv. Thaum cov tshuaj tiv thaiv pib, nws yuav txuas ntxiv mus reflux nyob rau hauv qhov tsis muaj qhov cua sov sab nraud.
Ib yam li ntawd, ether yog tsim los ntawm dab tsi? Ethyl ether , kuj hu ua Diethyl ether , zoo-paub tshuaj loog, feem ntau hu ua yooj yim ether, ib qho organic compound teej tug mus rau ib pawg loj ntawm cov tebchaw hu ua ethers; nws cov qauv molecular muaj ob pawg ethyl txuas los ntawm cov pa atom, xws li hauv C2H5OC2H5.
Tsuas yog li ntawd, ether siv rau dab tsi?
Vim nws cov nyhuv anesthetic, ether kuj yog siv li ib qho tshuaj txhaum cai rau induce sedation thiab euphoria. Ether tuaj yeem yog siv li ib qho hnyav los tsim cov tshuaj tsw qab, ua kom zoo dua lwm cov waxes lossis rog, lossis tsim lwm yam tshuaj.
Dab tsi yog anhydrous hnyav?
Tsis muaj dej txhais tau tias "tsis muaj dej." Hauv chemistry, cov khoom tsis muaj dej tau sau npe tsis muaj dej . Lub sij hawm feem ntau yog siv rau cov khoom siv crystalline tom qab cov dej ntawm crystallization raug tshem tawm. Piv txwv ntawm cov tshuaj tiv thaiv nrog anhydrous kuab tshuaj suav nrog cov tshuaj tiv thaiv Wurtz thiab cov tshuaj tiv thaiv Grignard.

Petroleum ether (tus tsiaj ether) yog cov kuab tshuaj nquag siv vim nws tus nqi qis dua piv rau lwm cov kuab tshuaj organic. Nws yog hygroscopic tsawg dua li diethyl ether, tsis tshua muaj nplaim taws dua li diethyl ether, thiab yog xaiv ntau dua rau hydrophobic lipids dua li diethyl ether
Puas yog ether thiab ethanol tib yam?
Yog tias ethanol yog (organic compound) ib qho yooj yim aliphatic cawv tau tsim los ntawm ethane los ntawm kev hloov ib qho hydrogen atom nrog ib pawg hydroxyl: ch3-ch2-oh thaum ether yog (organic compound | suav tau) ib qho chaw uas muaj cov pa oxygen atom txuas rau ob lub hydrocarbon. pab pawg
Dab tsi ntawm cov kuab tshuaj yog roj av ether polar lossis nonpolar)? Piav?
Cov roj av ether yog sib xyaw ntawm ntau cov hydrocarbons, feem ntau yog pentane thiab hexane, uas nyob rau hauv lem tsuas yog tsim los ntawm Carbon thiab Hydrogen, (uas tam sim no qhov tseem ceeb ntawm ze electronegativity), yuav luag tsis muaj polar
