Qhov sib txawv tseem ceeb ntawm ethylamine thiab aniline yog tias ethylamine yog ib qho aliphatic compound, thaum aniline yog ib qho aromatic compound.
Ob leeg ethylamine thiab aniline yog cov organic tebchaw uas muaj pawg amine (-NH2). Hauv ethylamine, pawg amine txuas rau pawg ethyl, tab sis hauv aniline, pawg amine txuas rau lub nplhaib benzene.
YEthylamine yog dab tsi?
Ethylamine yog ib qho aliphatic organic compound uas muaj cov tshuaj formula CH3CH2NH2Nws tshwm sim raws li cov pa tsis muaj xim thiab muaj ntxhiab tsw zoo li ammonia. Feem ntau, nws yog miscible nrog tag nrho cov kuab tshuaj. Cov molar loj ntawm cov tshuaj no yog 45.08 g / mol.
Daim duab 01: Cov qauv ntawm Ethylamine
Nyob rau hauv kev sib txuas ntawm ethylamine, muaj ob txoj haujlwm tseem ceeb rau kev tsim khoom loj ntawm cov khoom sib xyaw no. Txoj kev uas feem ntau yog cov tshuaj tiv thaiv ntawm ethanol thiab ammonia nyob rau hauv lub xub ntiag ntawm ib tug catalyst. Lwm txoj hauv kev yog qhov txo qis ntawm acetaldehyde.
Muaj ntau yam kev siv tseem ceeb ntawm ethylamine. Nws yog ib qho precursor rau zus tau tej cov herbicides xws li atrazine thiab simazine. Ntxiv mus, nws yog ib qho tseem ceeb precursor rau synthesis ntawm cyclidine dissociative anesthetic agents.
Aniline yog dab tsi?
Aniline yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2Nws muaj ib lub nplhaib benzene (ib pawg phenyl) txuas rau ib pawg amine (-NH2). Nws yog qhov yooj yim tshaj plaws aromatic amine vim tias tsis muaj cov khoom sib xws li pawg amine thiab cov nplhaib uas muaj ntxhiab. Tsis tas li ntawd, qhov sib xyaw no yog me ntsis pyramidalized thiab yog flatter dua li aliphatic amine. Nws qhov hnyav yog 93.13 g / mol. Tsis tas li ntawd, nws melting point yog -6.3 ° C thaum lub boiling point yog 184.13 ° C. Nws muaj tus ntxhiab tsw ntawm ntses lwj.
Industrially, peb tuaj yeem tsim qhov sib xyaw no ntawm ob kauj ruam. Thawj kauj ruam yog nitration ntawm benzene nrog ib tug concentrated sib tov ntawm nitric acid thiab sulfuric acid (ntawm 50 mus rau 60 ° C). Nws muab nitrobenzene. Tom qab ntawd peb tuaj yeem hydrogenate nitrobenzene rau hauv aniline nyob rau hauv lub xub ntiag ntawm ib tug hlau catalyst. Cov tshuaj tiv thaiv yog raws li nram no:
Ntxiv mus, hais txog kev siv, qhov sib xyaw no tsuas yog siv hauv kev tsim cov polyurethane precursors. Tsis tas li ntawd, peb tuaj yeem siv cov khoom sib xyaw no hauv kev tsim cov dyes, tshuaj, cov khoom tawg, plastics, photographic thiab rubbery chemicals, thiab lwm yam.
Qhov txawv ntawm Ethylamine thiab Aniline yog dab tsi?
Ethylamine yog ib qho aliphatic organic compound uas muaj cov tshuaj formula CH3CH2NH2thaum aniline yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2 Qhov sib txawv tseem ceeb ntawm ethylamine thiab aniline yog tias ethylamine yog ib qho aliphatic compound, thaum aniline yog ib qho tshuaj tsw qab. Tsis tas li ntawd, ethylamine tshwm sim raws li cov roj tsis muaj xim, tab sis aniline tshwm sim raws li cov xim tsis muaj xim rau cov kua daj.
Thaum xav txog cov txheej txheem tsim khoom, muaj ob txheej txheem rau ethylamine: cov tshuaj tiv thaiv ntawm ethanol thiab ammonia nyob rau hauv muaj cov catalyst thiab txo cov amination ntawm acetaldehyde. Ntxiv mus, rau aniline, muaj ob kauj ruam rau kev tsim khoom: nitration ntawm benzene nrog cov concentrated sib tov ntawm nitric acid thiab sulfuric acid ua raws li hydrogenating nitrobenzene rau hauv aniline nyob rau hauv lub xub ntiag ntawm ib tug hlau catalyst.
Hauv qab infographic muab qhov tseeb ntau ntxiv ntawm qhov sib txawv ntawm ethylamine thiab aniline.
Summary – Ethylamine vs Aniline
Ethylamine yog ib qho aliphatic organic compound uas muaj cov tshuaj formula CH3CH2NH2thaum Aniline yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2 Hauv cov ntsiab lus, Qhov sib txawv tseem ceeb ntawm ethylamine thiab aniline yog tias ethylamine yog ib qho aliphatic compound, thaum aniline yog ib qho aromatic compound.
