Qhov sib txawv tseem ceeb ntawm methylamine thiab dimethylamine yog tias methylamine muaj ib pawg methyl txuas nrog rau pawg amine, thaum dimethylamine muaj ob pawg methyl txuas rau pawg amine.
Methylamine thiab dimethylamine yog cov tshuaj amine yooj yim. Ob qho tib si cov organic tebchaw no tshwm sim raws li cov pa roj tsis muaj xim thiab muaj cov ntxhiab tsw zoo li ammonia.
Methylamine yog dab tsi?
Methylamine yog ib qho organic compound uas muaj cov tshuaj formula CH 5N. Lub compound muaj ib pawg methyl txuas nrog ib pawg amine. Yog li ntawd, nitrogen atom muaj ob hydrogen atoms txuas rau nws. Tsis tas li ntawd, qhov sib xyaw no yog qhov yooj yim tshaj plaws amine, thiab nws tshwm sim raws li cov roj tsis muaj xim nrog cov ntxhiab tsw zoo li fishy-ammonia. Cov molar loj yog 31.05 g / mol.
Nyob rau hauv cov txheej txheem ntawm methylamine, cov tshuaj tiv thaiv ntawm ammonia thiab methanol yog siv nyob rau hauv lub xub ntiag ntawm aluminosilicate catalyst. Txawm li cas los xij, hauv cov txheej txheem tsim khoom no, ob qho tib si dimethylamine thiab trimethylamine daim ntawv ua cov khoom sib koom ua ke. Ntawm no, peb yuav tsum hloov cov tshuaj tiv thaiv kinetics thiab reactant ratios kom tau cov khoom xav tau raws li qhov tshwm sim loj.
Dimethylamine yog dab tsi?
Dimethylamine yog cov organic compound uas muaj cov tshuaj formula (CH 3)2NH. Ntawm no, cov compound muaj ob pawg methyl txuas rau pawg amine. Yog li ntawd, nitrogen atom nyob rau hauv pawg amine tsuas muaj ib qho hydrogen atom txuas rau nws dua li cov methyl pawg. Nws tshwm sim raws li cov pa tsis muaj xim thiab muaj cov ntxhiab tsw ntses. Ntxiv mus, nws cov molar loj yog 45.08 g / mol. Peb categorize nws raws li ib tug thib ob amine vim yog ob pawg methyl.
Tsis tas li, qhov sib xyaw no tshwm sim hauv ntau cov nroj tsuag thiab tsiaj txhu. Tsis tas li ntawd, peb tuaj yeem tsim cov tshuaj no los ntawm cov tshuaj tiv thaiv ntawm methanol thiab ammonia nyob rau hauv lub xub ntiag ntawm ib tug catalyst, siab kub thiab siab tej yam kev mob.
Qhov txawv ntawm Methylamine thiab Dimethylamine yog dab tsi?
Methylamine yog cov organic compound uas muaj cov tshuaj formula CH 5N thaum Dimethylamine yog cov organic compound uas muaj cov tshuaj formula (CH3)2NH. Yog li, qhov sib txawv tseem ceeb ntawm methylamine thiab dimethylamine yog tias methylamine muaj ib pawg methyl txuas nrog rau pawg amine, thaum dimethylamine muaj ob pawg methyl txuas rau pawg amine. Yog li ntawd, dimethylamine yog lub hauv paus muaj zog dua methylamine.
Ntxiv mus, peb tuaj yeem tsim cov tshuaj sib xyaw no los ntawm cov tshuaj tiv thaiv ntawm methanol thiab ammonia nyob rau hauv lub xub ntiag ntawm aluminosilicate catalyst, tab sis nws muab methylamine, dimethylamine thiab trimethylamine ua cov khoom sib koom ua ke. Yog li, peb yuav tsum tswj xyuas qhov tseeb ntawm cov tshuaj tiv thaiv. xws li kev kub siab thiab kub kub yuav muab ntau dua dimethylamine.
Hauv qab infographic qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm methylamine thiab dimethylamine.
Summary – Methylamine vs Dimethylamine
Methylamine yog cov organic compound uas muaj cov tshuaj formula CH 5N thaum Dimethylamine yog cov organic compound uas muaj cov tshuaj formula (CH3)2NH. Qhov sib txawv tseem ceeb ntawm methylamine thiab dimethylamine yog tias methylamine muaj ib pawg methyl txuas nrog rau pawg amine, thaum dimethylamine muaj ob pawg methyl txuas rau pawg amine.
