Qhov sib txawv tseem ceeb ntawm triethylamine thiab triethanolamine yog tias triethylamine muaj peb pawg ethyl txuas rau tib lub atom nitrogen whereas triethanolamine muaj peb ethyl cawv pawg txuas rau tib lub atom nitrogen.
Cov tshuaj sib xyaw ua ke triethylamine thiab triethanolamine yog cov organic tebchaw uas muaj nitrogen atoms. Cov tebchaw no muaj nitrogen atom ntawm qhov chaw ntawm lub molecule, thiab muaj peb cov organic moieties txuas mus rau lub chaw nitrogen.
Triethylamine yog dab tsi?
Triethylamine yog cov organic compound uas muaj cov tshuaj formula N(CH2CH3)3 Cov tshuaj no yog sau ua Et3N. Nws yog nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub, thiab nws tshwm raws li ib tug volatile, tsis muaj kob kua. Nws muaj cov ntxhiab tsw muaj zog uas zoo li tus ntxhiab ntawm ammonia.
Daim duab 01: Cov Qauv Tshuaj ntawm Triethylamine
Triethylamine tuaj yeem tsim los ntawm alkylation ntawm ammonia nrog ethanol. Lub pKa ntawm cov kua no yog hais txog 10.75 yog li, nws tuaj yeem siv rau kev npaj cov kev daws teeb meem ntawm pH 10.75. Triethylamine yog me ntsis dej-soluble. Txawm li cas los xij, nws yog miscible nrog qee cov kuab tshuaj organic ib yam nkaus. e.g. acetone, ethanol, thiab lwm yam. Cov hydrochloride ntsev ntawm triethylamine yog triethylamine hydrochloride, uas yog cov xim tsis muaj xim, tsis muaj ntxhiab, thiab hygroscopic hmoov.
Muaj ntau daim ntawv thov tseem ceeb ntawm triethylamine. Feem ntau, nws yog siv nyob rau hauv lub synthesis tshuaj nyob rau hauv cov organic chemistry ua lub hauv paus. E.g. Kev npaj ntawm esters, amides los ntawm acyl chlorides. Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv kev tsim cov quaternary ammonium compounds rau kev lag luam textile. Nws kuj tseem muaj txiaj ntsig zoo li catalyst thiab acid neutralizer rau cov tshuaj tiv thaiv condensation. Tsis tas li ntawd, nws muaj txiaj ntsig zoo li nruab nrab rau kev tsim tshuaj, tshuaj tua kab, thiab lwm yam.
Triethanolamine yog dab tsi?
Triethanolamine yog cov organic compound uas muaj cov tshuaj formula N(CH2CH2OH)3Nws muaj peb pawg cawv nrog rau lub hauv paus nitrogen atom. Yog li, peb tuaj yeem faib nws li triamine thiab ua triol. Cov tshuaj no tshwm sim raws li cov kua tsis muaj xim thiab viscous ntawm chav tsev kub. Txawm li cas los xij, yog tias nws muaj impurities, cov kua no tshwm hauv cov xim daj.
Peb tuaj yeem tsim triethanolamine los ntawm cov tshuaj tiv thaiv ntawm ethylene oxide thiab aqueous ammonia. Txawm li cas los xij, qhov tshuaj tiv thaiv no tuaj yeem tsim ethanolamine thiab diethanolamine, thiab. Los ntawm kev hloov cov stoichiometry ntawm cov reactants, peb tuaj yeem hloov qhov piv ntawm cov khoom tsim los ntawm cov tshuaj tiv thaiv no.
Muaj ntau daim ntawv thov ntawm triethanolamine. Feem ntau, nws muaj txiaj ntsig zoo rau kev tsim cov surfactants. Ntxiv mus, nws yog ib qho khoom muaj nyob rau hauv ob qho tib si kev lag luam thiab cov neeg siv khoom. Triethylamine tuaj yeem ua rau cov roj ntsha tsis zoo, kho pH, thiab solubilize roj thiab lwm cov khoom xyaw uas muaj dej me ntsis.
Qhov txawv ntawm Triethylamine thiab Triethanolamine yog dab tsi?
Triethylamine thiab triethanolamine yog cov organic tebchaw uas muaj nitrogen atoms ntawm qhov chaw ntawm cov molecule. Qhov sib txawv tseem ceeb ntawm triethylamine thiab triethanolamine yog tias triethylamine muaj peb pawg ethyl txuas nrog tib lub nitrogen atom thaum triethanolamine muaj peb pawg ethyl cawv uas txuas nrog tib lub atom nitrogen. Triethylamine yog ib qho amine compound, thaum triethanolamine yog ib qho cawv cawv.
Ntxiv mus, triethylamine muaj lub hauv paus nitrogen atom txuas rau peb pawg ethyl thaum triethanolamine muaj lub hauv paus nitrogen atom sib txuas rau peb pawg ethyl cawv. Yog li, qhov no yog qhov sib txawv ntawm triethylamine thiab triethanolamine.
Hauv qab infographic tabulates ntau qhov sib txawv ntawm triethylamine thiab triethanolamine.
Summary – Triethylamine vs Triethanolamine
Triethylamine thiab triethanolamine yog cov organic tebchaw uas muaj nitrogen atoms ntawm qhov chaw ntawm cov molecule. Qhov sib txawv tseem ceeb ntawm triethylamine thiab triethanolamine yog tias triethylamine muaj peb pawg ethyl txuas nrog tib lub nitrogen atom thaum triethanolamine muaj peb pawg ethyl cawv uas txuas nrog tib lub atom nitrogen.
