Kapangidwe ka thupi ndi mankhwala

Ethanolamine imatchedwanso "aminoethanol". Fomula ya mankhwala HOCH2CH2NH2. Kulemera kwa molekyulu 61.08. Madzi okhuthala opanda utoto. Osavuta kuyamwa chinyezi ndi fungo la ammonia. Mphamvu yokoka 1.0117 (25/4℃). Malo osungunuka 10.3℃. Malo otentha 170.8℃. Chizindikiro cha refractive 1.4539. Imasakanikirana ndi madzi, methanol ndi acetone, imasungunuka pang'ono mu benzene ndi ether, ndipo imasungunuka pang'ono mu n-pentane. Ndi yamchere kwambiri, yokhala ndi dissociation constant K=3.39×1Chemicalbook0-10 (25℃); pH ya 25% yamadzimadzi ndi 12.1, ndipo imatha kuyamwa carbon dioxide mumlengalenga. Hydrochloride yake ndi kristalo ya hygroscopic yokhala ndi melting point ya 75 mpaka 77°C. Yopangidwa ndi mafakitale chifukwa cha ethylene oxide ndi ammonia. Ethanolamine ndi mankhwala ofunikira omwe amagwiritsidwa ntchito popanga mankhwala, zonunkhira, ma surfactants, zokutira, ma emulsifiers, ndi zina zotero. Ndi chinthu chofewetsa chikopa komanso chotulutsa mankhwala ophera tizilombo; chingagwiritsidwenso ntchito poyeretsa mpweya kuti chichotse carbon dioxide ndi hydrogen sulfide mu mpweya.

Ntchito

Ethanolamine imagwiritsidwa ntchito popanga mankhwala osiyanasiyana komanso zoletsa. Gwiritsani ntchito ethanolamine ngati zopangira popanga mankhwala olowa m'malo mwa carboxyl, omwe ali ndi mphamvu yolimbana ndi chotupa. Amagwiritsidwanso ntchito popanga aminoquinolones okhala ndi mphamvu yotsutsana ndi Plasmodium.
