Qhov sib txawv tseem ceeb ntawm phenylamine thiab aminobenzene yog lub npe phenylamine piav qhia tias aniline muaj ib pawg phenyl thiab ib pawg amine thaum lub npe aminobenzene piav qhia tias aniline muaj ib pawg amino hloov mus rau lub nplhaib benzene.
Ob lo lus phenylamine thiab aminobenzene yog cov npe nrov rau cov tshuaj aniline. Yog li ntawd, cov no yog ob lub npe rau tib lub compound. Tsis tas li ntawd xwb, qhov sib txawv ntawm phenylamine thiab aminobenzene yog qhov nthuav dav txhua lub npe muab hais txog cov qauv ntawm cov khoom sib xyaw no.
Phenylamine yog dab tsi?
Phenylamine yog ib lub npe nrov rau cov tshuaj, aniline. Lub npe piav qhia tias aniline muaj ib pawg phenyl thiab ib pawg amine. Aniline yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H5NH2 Nws muaj phenyl pawg. (ib lub nplhaib benzene) nrog ib pawg amine txuas (-NH2). Tsis tas li ntawd, qhov no yog qhov yooj yim tshaj plaws aromatic amine. 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. Ntxiv mus, lub melting point yog -6.3 ° C, thiab 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 muaj peev xwm 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:
Daim duab 01: Cov qauv tshuaj ntawm Aniline
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.
Aminobenzene yog dab tsi?
Aminobenzene yog lwm lub sijhawm rau cov khoom sib xyaw uas paub los ntawm aniline lossis phenylamine. Lub npe piav qhia tias aniline muaj ib pab pawg amino hloov mus rau lub nplhaib benzene.
Qhov txawv ntawm Phenylamine thiab Aminobenzene yog dab tsi?
Phenylamine thiab aminobenzene yog ob lub npe uas peb siv rau tib cov tshuaj hu ua aniline; txhua lub npe muab cov ntsiab lus hais txog tus qauv ntawm lub compound. Qhov sib txawv tseem ceeb ntawm phenylamine thiab aminobenzene yog lub npe phenylamine piav qhia tias aniline muaj ib pawg phenyl thiab ib pawg amine thaum lub npe aminobenzene piav qhia tias aniline muaj cov amino pawg hloov mus rau lub nplhaib benzene.
Summary – Phenylamine vs Aminobenzene
Phenylamine thiab aminobenzene yog ob lub npe uas peb siv rau tib lub npe tshuaj hu ua aniline, thiab txhua lub npe muab cov ntsiab lus hais txog cov qauv ntawm cov khoom sib xyaw. Qhov sib txawv tseem ceeb ntawm phenylamine thiab aminobenzene yog lub npe phenylamine piav qhia tias aniline muaj ib pawg phenyl thiab ib pawg amine thaum lub npe aminobenzene piav qhia tias aniline muaj cov amino pawg hloov mus rau lub nplhaib benzene. Txawm li cas los xij, ob lub ntsiab lus npe tib yam tshuaj lom neeg.
