Qhov sib txawv tseem ceeb ntawm ethanamide thiab methylamine yog tias ethanamide yog ib qho yooj yim amide uas tshwm sim raws li cov khoom tsis muaj xim, whereas methylamine yog ib qho yooj yim amine uas tshwm sim raws li cov xim tsis muaj xim thiab hygroscopic khoom compound.
Ethanamide thiab methylamine yog cov organic tebchaw tseem ceeb. Ethanamide los yog acetamide yog cov organic compound uas muaj cov tshuaj formula CH3CONH2. Methylamine, ntawm qhov tod tes, yog cov organic compound uas muaj cov tshuaj formula CH3NH2.
Ethanamide yog dab tsi?
Ethanamide yog cov organic compound uas muaj cov tshuaj formula CH3CONH2. Nws yog qhov yooj yim tshaj plaws amide compound, thiab nws tsim raws li ib tug derivative ntawm acetic acid. Cov tshuaj no muaj nyob rau hauv ib qho kev sib xyaw nruab nrab ntawm acetone thiab urea. Acetone compound muaj ob pawg methyl txuas rau C=O chaw, thaum urea muaj ob pawg amide txuas rau C=O chaw. Ntxiv mus, ethanamide yog ib qho kev sib xyaw ua ke, lossis peb tuaj yeem tsim nws hauv kev lag luam.
Daim duab 01: Cov Qauv Tshuaj ntawm Ethanamide
Cov tshuaj no muaj cov molar loj ntawm 58 g / mol, thiab nws tshwm sim raws li cov xim tsis muaj xim, hygroscopic cov khoom sib xyaw uas tsis muaj ntxhiab thaum ntshiab. Nws muab cov ntxhiab tsw zoo li nas thaum nws muaj impurities.
Thaum xav txog cov txheej txheem tsim khoom ntawm ethanamide, ntawm chav kuaj ntsuas, peb tuaj yeem npaj nws los ntawm lub cev qhuav dej ntawm ammonium acetate. Tsis tas li ntawd, peb tuaj yeem siv cov tshuaj tiv thaiv aminolysis rau acetylacetone nyob rau hauv kev txo qis amination. Raws li lwm txoj kev, peb tuaj yeem npaj ethanamide los ntawm anhydrous acetic acid. Ntawm qhov ntsuas kev lag luam, peb tuaj yeem tsim ethanamide los ntawm dehydrating ammonium acetate los yog los ntawm hydration ntawm acetonitrile.
Muaj ntau qhov kev siv ethanamide, uas suav nrog kev siv nws ua cov yas yas thiab ua cov kuab tshuaj ua haujlwm. Piv txwv li, molten ethanamide yog ib qho tseem ceeb raws li ib tug zoo hnyav nyob rau hauv dissolving ntau inorganic tebchaw vim nws siab dielectric tas li. Ntxiv mus, ethanamide muaj cov ntawv thov hauv electrochemistry thiab organic synthesis, tshuaj, tshuaj tua kab ntau lawm, thiab kev tsim tshuaj antioxidant. Tsis tas li ntawd, qhov sib xyaw no muaj txiaj ntsig zoo ua ntej rau thioacetamide.
Methylamine yog dab tsi?
Methylamine yog cov organic compound uas muaj cov tshuaj formula CH3NH2. Nws tshwm sim raws li cov roj tsis muaj xim uas tsim los ntawm cov roj ammonia. Tsis zoo li hauv ammonia molecule, methylamine molecule muaj ib hydrogen atom hloov nrog ib pawg methyl. Peb tuaj yeem txheeb xyuas cov tshuaj methylamine ua cov amine yooj yim tshaj plaws.
Daim duab 02: Cov Qauv Tshuaj ntawm Methylamine
Peb tuaj yeem pom cov tshuaj methylamine raug muag raws li cov tshuaj hauv methanol, ethanol, tetrahydrofuran, lossis dej. Nws muaj ib tug fishy, ammoniacal tsw. Peb tuaj yeem tsim cov tshuaj methylamine ua lag luam los ntawm cov tshuaj tiv thaiv ntawm ammonia nrog methanol thaum muaj aluminosilicate catalyst. Hauv chav kuaj, peb tuaj yeem tsim methylamine los ntawm ntau txoj hauv kev, xws li cov tshuaj tiv thaiv ntawm formaldehyde nrog ammonium chloride.
Muaj ntau daim ntawv thov ntawm methylamine: siv nws ua lub hauv paus tsis muaj zog amine, ua tus thawj coj ntawm kev tsim cov tshuaj xws li ephedrine thiab theophylline.
Qhov txawv ntawm Ethanamide thiab Methylamine yog dab tsi?
Ethanamide thiab methylamine yog ib qho tseem ceeb nitrogen-muaj cov organic tebchaw. Qhov sib txawv tseem ceeb ntawm ethanamide thiab methylamine yog tias ethanamide yog ib qho yooj yim amide uas tshwm sim raws li cov khoom tsis muaj xim whereas methylamine yog ib qho yooj yim amine uas tshwm sim raws li cov khoom tsis muaj xim thiab hygroscopic. Ntxiv mus, ethanamide tuaj yeem npaj tau los ntawm lub cev qhuav dej ntawm ammonium acetate thaum methylamine tuaj yeem npaj los ntawm ntau txoj hauv kev xws li cov tshuaj tiv thaiv ntawm formaldehyde nrog ammonium chloride.
Cov lus qhia hauv qab no nthuav tawm qhov sib txawv ntawm ethanamide thiab methylamine hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Ethanamide vs Methylamine
Ethanamide thiab methylamine yog ib qho tseem ceeb nitrogen-muaj cov organic tebchaw. Qhov sib txawv tseem ceeb ntawm ethanamide thiab methylamine yog tias ethanamide yog ib qho yooj yim amide uas tshwm sim raws li cov khoom tsis muaj xim thaum methylamine yog ib qho yooj yim amine uas tshwm sim raws li cov xim tsis muaj xim thiab hygroscopic khoom compound.
