Diethanolamine 111-42-2 puriy: ≥99%

Chiyambi:

Ethanolamine (EA) ndi amino alcohol yofunika kwambiri, kuphatikizapo monoethanolamine (MEA), diethanolamine (DEA), ndi triethanolamine (TEA). Ethanolamine ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri mu ma surfactants, zotsukira zopangira, zowonjezera mafuta, utomoni wopangidwa ndi rabara ndi pulasitiki, zofulumizitsa, zovulcanizer, ndi zotulutsa thovu, komanso poyeretsa mpweya, zoletsa kuzizira, kusindikiza ndi kuyika utoto, mankhwala, mankhwala ophera tizilombo, zomangamanga, ndi ntchito zankhondo. Zinthu zambiri zomwe zimapezeka mu ethanolamine ndi zinthu zofunika kwambiri zochepetsera poizoni ndipo sizikupezeka ku China. Chifukwa chake, kuyesetsa kowonjezereka pakupanga ndi kugwiritsa ntchito ethanolamine ndikofunikira kuti zikwaniritse kufunikira kwa mankhwala abwino m'nyumba ndikulimbikitsa kukula kwachangu kwa makampani a ethanolamine.

Diethanolamine, yomwe imadziwikanso kuti bishydroxyethylamine ndi 2,2′-iminobisethanol, ndi madzi oyera a kristalo kapena opanda mtundu omwe ali ndi hygroscopicity yamphamvu. Amasungunuka mosavuta m'madzi, methanol, ethanol, acetone, ndi benzene. Kusungunuka kwake mu benzene (g/100g) pa 25°C ndi 4.2, ndipo mu ether ndi 0.8. Ntchito zake zikuphatikizapo: chotsukira mpweya, chomwe chimayamwa mpweya wa asidi wopangidwa ndi mankhwala monga carbon dioxide, hydrogen sulfide, ndi sulfure dioxide. Yankho la "Benfil", lomwe limagwiritsidwa ntchito mumakampani opanga ammonia, limapangidwa makamaka ndi mankhwalawa. Limagwiritsidwanso ntchito ngati emulsifier, lubricant, shampu, thickener, ndi zina zowonjezera. Ndi organic synthesis intermediate yomwe imagwiritsidwa ntchito popanga zinthu zopangira sopo, zosungira, ndi mankhwala a tsiku ndi tsiku (monga surfactants). Limagwiritsidwanso ntchito popanga morpholine.

Ntchito: Diethanolamine imagwiritsidwa ntchito ngati zinthu zopangira zinthu zosungiramo mankhwala m'makampani opanga mankhwala, ngati chinthu cholumikizirana popanga thovu la polyurethane lolimba kwambiri, komanso ngati sopo wa ma pistoni a injini ya ndege akasakanikirana ndi triethanolamine. Imayanjana ndi mafuta acids kupanga alkyl alcohol acyl. Imagwiritsidwanso ntchito ngati zinthu zopangira zinthu zachilengedwe, zinthu zopangira mankhwala opangira zinthu zosungunulira, komanso choyamwa mpweya wa asidi. Imagwiritsidwa ntchito ngati chokhuthala komanso chosinthira thovu m'ma shampu ndi sopo wopepuka, ngati chothandizira pakati pamakampani opanga zinthu zachilengedwe, komanso ngati chosungunulira m'makampani opanga mankhwala. Ili ndi ntchito zambiri m'makampani ochapira, makampani odzola, ulimi, makampani omanga, ndi mafakitale achitsulo.
