Diethanolamine 111-42-2 saafi ah: ≥99%

Taariikhda:

Ethanolamine (EA) waa aalkolada amino ee ugu muhiimsan, oo ay ku jiraan monoethanolamine (MEA), diethanolamine (DEA), iyo triethanolamine (TEA). Ethanolamine waa dhexdhexaad muhiim ah oo dabiici ah oo si weyn loogu isticmaalo surfactants, saabuunta macmalka ah, waxyaabaha lagu daro batroolka, resin synthetic iyo plasticizers caag ah, dardar-geliyayaasha, vulcanizers, iyo wakiilada xumbo, iyo sidoo kale nadiifinta gaaska, ka hortagga qabowga dareeraha ah, daabacaadda iyo rinjiyeynta, daawooyinka, sunta cayayaanka, dhismaha, iyo codsiyada militariga. Badeecooyin badan oo ethanolamine ah oo hoos yimaada waa dhexdhexaad kiimiko oo muhiim ah waxayna sidoo kale ku yar yihiin Shiinaha. Sidaa darteed, kordhinta dadaallada horumarinta iyo codsiga ethanolamine waa muhiim si loo daboolo baahida kiimikada ee gudaha iyo kor u qaadista horumarka degdegga ah ee warshadaha ethanolamine.

Diethanolamine, oo sidoo kale loo yaqaan bishydroxyethylamine iyo 2,2′-iminobisethanol, waa dareere cad oo crystalline ah ama aan midab lahayn oo leh hygroscopicity xooggan. Si fudud ayuu ugu milmi karaa biyaha, methanol, ethanol, acetone, iyo benzene. Milmideeda benzene (g/100g) heerkul ah 25°C waa 4.2, ether-na waa 0.8. Isticmaalkeeda waxaa ka mid ah: nadiifiye gaas ah, oo nuugaya gaasaska aashitada kiimikada ku shaqeeya sida kaarboon laba ogsaydh, hydrogen sulfide, iyo sulfur dioxide. Xalka "Benfil", ee loo isticmaalo warshadaha isku-darka ammonia, wuxuu inta badan ka kooban yahay badeecadan. Waxa kale oo loo isticmaalaa emulsifier, saliid, shaambo, dhumuc-dhejin, iyo waxyaabo kale oo lagu daro. Waa dhexdhexaad isku-darka dabiiciga ah oo loo isticmaalo soo saarista walxaha ceeriin ee saabuunta, ilaaliyayaasha, iyo alaabada kiimikada maalinlaha ah (sida surfactants). Waxa kale oo loo isticmaalaa isku-darka morpholine.

Isticmaalka: Diethanolamine waxaa loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay kaydka warshadaha dawooyinka, sida wakiil isku xidha soo saarista xumbo polyurethane oo adkaysi sare leh, iyo sida saabuunta loogu talagalay bistoolajiyada matoorka diyaaradaha marka lagu qaso triethanolamine. Waxay la falgashaa asiidhyada dufanka leh si ay u sameeyaan acyl alkyl alcohol. Waxa kale oo loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay isku-darka dabiiciga ah, walxo ceeriin ah oo loogu talagalay surfactants, iyo nuugaya gaaska aashitada. Waxaa loo isticmaalaa sidii dhumuc-dherer iyo wax-ka-beddele xumbo shaambooyada iyo saabuunta fudud, sida dhexdhexaadka warshadaha isku-darka dabiiciga ah, iyo sida dareere warshadaha dawooyinka. Waxay leedahay isticmaalyo badan oo warshadaha dharka lagu dhaqo, warshadaha qurxinta, beeraha, warshadaha dhismaha, iyo warshadaha birta.
