Ethanolamines yog ib tsev neeg ntawm cov organic tshuaj sib xyaw ua ke nyob rau hauv ntau kev lag luam {}}}}}}}} Ntawm cov feem ntau cov yog monoethanolamine (mea), diethanoline (dea), thiab triethanolamine (tshuaj yej). Thaum lub sij hawm muaj feem cuam tshuam, txhua tus ethanolamine muaj cov tshuaj lom neeg thiab cov ntawv thov ua tiav, ua rau nws muaj qhov sib txawv thaum muaj kev siv.
Dab tsi yog ethanolamines?
Ethanolamines yog alkanolamines, lub ntsiab lus lawv muaj ob pawg amine (-nh2, -nh, lossis -n) thiab pab pawg hydroxyl). Tus naj npawb ntawm ethanol cov pab pawg txuas nrog rau nitrogen atom tshwj xeeb meEA, dea, thiab tshuaj yej:
- Monoethanolamamine (mea): ib pawg ephanol
- Diethanmamine (dea): Ob pawg ethanol
- Triethanline (Tshuaj yej): Peb pawg ethanol
Qhov kev hloov pauv no cuam tshuam rau lawv cov kev pheej hmoo, solubility, thiab haum rau cov txheej txheem tshuaj sib txawv thiab muaj cov txheej txheem sib txawv.
Monoethanolamamine (mea)
Tshuaj mis: Hoch₂ch₂nh₂
Cov Ntawv Thov:
Monoethanolamineyog cov organic tsis muaj kob nrog cov organic uas tsis muaj zog thiab yog cov reagent ntau hauv cov organic synthesis. Nws yog ib qho tseem ceeb biochemical lub sij hawm siv dav hauv cov chaw ntawm cov tshuaj, tshuaj tua kab, dyes, thiab hluavtaws resins.
Diethanmamine (dea)
Tshuaj mis: (hoch₂ch₂) ₂nh
Cov Ntawv Thov:
Deayog cov kua ntau ntau dua li mea thiab muaj cov alkality alkalinity. Nws yog siv nyob rau hauv:
DEA yog cov organic heev cov organic sib xyaw nrog cov ntaub ntawv ntau hauv kev lag luam xws li inks, txheej, thiab kev tsim tshuaj lom neeg.
Triethanine (Tshuaj yej)
Tshuaj mis: N (CH₂CH₂₂OH) ₃
Cov Ntawv Thov:
Tshuaj yej yog cov viscous heev, hygroscopic compound nrog peb pawg hydroxyl, ua rau nws zoo tagnrho rau:
Tshuaj yej yog siv dav hauv ntau daim teb xws li chemistry, kws tshuaj, txheej, thiab metallurgy. Nws tseem thov rau cov tshuaj pleev ib ce, roj nplua nyeem, thiab surfactants.
Nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau cov kws sau, chaw tsim khoom, thiab cov kws tsim khoom siv, thiab cov kws tsim nyog ua haujlwm thiab kev xav tau kev cai.
