Ethers li Solvents Vim tias diethyl ether muaj lub sijhawm dipole, cov tshuaj polar tau yooj yim yaj hauv nws. Polar tebchaw uas muaj peev xwm ua hauj lwm raws li hydrogen daim ntawv cog lus pub rau yaj nyob rau hauv diethyl ether vim hais tias lawv muaj peev xwm tsim hydrogen bonds rau cov nonbonding electron khub ntawm ether oxygen atoms. Ethers yog aprotic.
Vim li cas peb thiaj siv ether?
Ua ntej nws txoj kev loj hlob raws li kev phais mob, ether tau siv thoob plaws hauv keeb kwm ntawm cov tshuaj, suav nrog kev kho mob xws li scurvy lossis pulmonary o. Cov ntxhiab tsw qab ntxiag, tsis muaj xim thiab cov kua nplaum heev, ether tuaj yeem vaporized rau hauv cov pa uas ua rau mob loog tab sis ua rau cov neeg mob tsis nco qab.
Vim li cas diethyl ether siv los ua cov kuab tshuaj hauv Grignard cov tshuaj tiv thaiv?
q Diethyl ether yog cov kuab tshuaj zoo tshwj xeeb rau kev tsim cov Grignard reagents vim ethers tsis yog-acidic (aprotic). Dej los yog cawv yuav protonate thiab yog li rhuav tshem Grignard reagent, vim hais tias Grignard carbon yog heev nucleophilic. Qhov no yuav tsim ib hydrocarbon.
YPuas yog diethyl ether acidic lossis yooj yim?
Ethyl ether H3CH2−O−CH2CH3 yog Bronsted base vim tias tuaj yeem txais tau ib qho proton los ntawm cov kua qaub HX uas muab lub hauv paus conjugate X- thiab cov conjugate acid H3CH2−OH+ − CH2CH3.
Diethyl ether siv rau dab tsi?
Diethyl ether (CAS 60-29-7) yog ib feem ntawm cov kua dej pib thiab siv ua cov kuab tshuaj hauv kev tsim khoom.hluavtaws dyes thiab plastics. Vim tias nws cov yam ntxwv diethyl ether tau siv dav hauv ntau lub tebchaws los ua tshuaj loog, tab sis tom qab ntawd tau hloov los ntawm lwm yam tshuaj hauv xyoo 1960.
