Cov khoom siv lub cev thiab tshuaj lom neeg

Ethanolamine tseem hu ua "aminoethanol". Cov mis tshuaj HOCH2CH2NH2. Qhov hnyav molecular 61.08. Cov kua nplaum tsis muaj xim. Yooj yim nqus cov dej noo thiab tsw ntawm ammonia. Lub zog tshwj xeeb 1.0117 (25/4 ℃). Melting point 10.3 ℃. Boiling point 170.8 ℃. Refractive index 1.4539. Nws yog miscible nrog dej, methanol thiab acetone, me ntsis soluble hauv benzene thiab ether, thiab me ntsis soluble hauv n-pentane. Nws yog alkaline muaj zog, nrog rau qhov dissociation tas mus li K = 3.39 × 1Chemicalbook 0-10 (25 ℃); lub pH ntawm 25% aqueous kua yog 12.1, thiab nws tuaj yeem nqus cov pa roj carbon dioxide hauv huab cua. Nws cov hydrochloride yog cov siv lead ua hygroscopic nrog lub melting point ntawm 75 txog 77 ° C. Industrially tsim los ntawm kev sib xyaw ntawm ethylene oxide thiab ammonia. Ethanolamine yog ib yam khoom siv tshuaj tseem ceeb uas siv rau hauv tshuaj, txuj lom, surfactants, coatings, emulsifiers, thiab lwm yam. Nws kuj yog ib qho tshuaj ua kom tawv mos thiab tshuaj tua kab; nws kuj tseem siv tau rau kev ntxuav roj kom tshem tawm cov pa roj carbon dioxide thiab hydrogen sulfide hauv cov roj.

Siv

Ethanolamine siv rau hauv kev npaj ntau yam tshuaj thiab cov tshuaj inhibitors. Siv ethanolamine ua cov khoom siv raw los tsim cov tshuaj carboxyl hloov pauv, uas muaj cov haujlwm tiv thaiv qog noj ntshav zoo. Kuj tseem siv rau hauv kev tsim cov aminoquinolones nrog cov haujlwm tiv thaiv Plasmodium.
