Qhov sib txawv tseem ceeb ntawm aniline thiab benzylamine yog tias pawg amine ntawm aniline txuas rau lub nplhaib benzene ncaj qha whereas pawg amine ntawm benzylamine txuas rau lub nplhaib benzene indirect, los ntawm ib qho -CH 2 – pab pawg.
Aniline thiab benzylamine yog cov tshuaj tsw qab organic. Ob lub tebchaw no muaj benzene rings thiab amine pawg, tab sis pawg amine muab cov benzene sib txawv; ncaj qha los yog tsis ncaj. Yog li ntawd, ob lub tebchaw muaj tshuaj lom neeg thiab lub cev sib txawv.
Aniline yog dab tsi?
Aniline yog cov tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2Nws muaj ib pawg phenyl (ib lub nplhaib benzene) nrog ib pawg amine txuas (-NH2). Nws yog qhov yooj yim tshaj plaws aromatic amine. Ntxiv mus, qhov sib xyaw no yog me ntsis pyramidalized thiab yog flatter dua li aliphatic amine. Nws qhov hnyav yog 93.13 g / mol. Lub 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;
Tsis tas li ntawd, qhov sib xyaw no feem ntau 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.
Benzylamine yog dab tsi?
Benzylamine yog ib qho tshuaj tsw qab organic nrog cov tshuaj formula C 6 H 5CH 2 NH2 Nws muaj ib pab pawg amine txuas rau pawg phenyl ntawm ib pawg -CH2-. Tsis tas li ntawd, qhov sib xyaw no tshwm sim raws li cov kua tsis muaj xim, thiab nws muaj cov ntxhiab tsw zoo li ammonia. Cov molar loj ntawm Benzylamine yog 107.15 g / mol. Lub melting point yog 10 ° C thaum lub boiling point yog 185 ° C.
Peb tuaj yeem tsim cov tshuaj no los ntawm cov tshuaj tiv thaiv ntawm benzyl chloride nrog ammonia. Tsis tas li, peb tuaj yeem tsim nws los ntawm benzonitrile txo. Cov tshuaj tiv thaiv yog raws li nram no;
Ntxiv mus, qhov sib xyaw no yog ib qho ua ntej rau cov organic synthesis thiab ntau cov tshuaj.
Qhov txawv ntawm Aniline thiab Benzylamine yog dab tsi?
Aniline yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2 Thaum Benzylamine yog ib qho tshuaj tsw qab organic uas muaj cov tshuaj formula C6H5CH2NH 2 Qhov sib txawv tseem ceeb ntawm aniline thiab benzylamine yog nyob rau hauv aniline pawg amine txuas nrog lub nplhaib benzene ncaj qha whereas hauv benzylamine pawg amine txuas lub nplhaib benzene indirect, los ntawm ib pawg -CH2.
Ntxiv mus, peb tuaj yeem tsim aniline ntawm nitration ntawm benzene ua raws li hydrogenation nitrobenzene rau hauv aniline whereas peb tuaj yeem tsim benzylamine los ntawm cov tshuaj tiv thaiv ntawm benzyl chloride nrog ammonia. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm aniline thiab benzylamine yog lawv cov ntxhiab tsw. Aniline muaj cov ntxhiab tsw ntawm cov ntses lwj thaum cov ntxhiab ntawm benzylamine zoo ib yam li cov ntxhiab ntawm ammonia.
Summary – Aniline vs Benzylamine
Aniline yog cov tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2 Thaum Benzylamine yog ib qho tshuaj tsw qab organic uas muaj cov tshuaj formula C6H5CH2NH 2 Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm aniline thiab benzylamine yog nyob rau hauv aniline, pawg amine txuas nrog lub nplhaib benzene ncaj qha whereas, hauv benzylamine, pawg amine txuas lub nplhaib benzene indirect, los ntawm a - CH2– group.
