Gabatarwa
Diethyl barasa monoisopropanolamine wani nau'in kwayoyin halitta ne, dabarar sinadarai C7H17O3N, mara launi ko rawaya mai haske tare da dandanon ammonia yana motsa ruwa mai danko, barga a dakin da zazzabi da matsa lamba.Diethyl barasa monoisopropanolamine sabon nau'in kayan taimako ne na kore mai niƙa, wanda ke da tasirin taimakon niƙa a fili, kuma ana amfani da shi sosai a taimakon niƙan siminti.
(1) Diethanolamine monoisopropyl olamine ne yafi amfani da surfactants, yadu amfani a sinadaran albarkatun kasa, pigments, magani, gini kayan da sauran filayen, a ciminti Additives, fata kula kayayyakin da yadi softener more aikace-aikace.
(2) A halin yanzu, a fagen niƙa da siminti AIDS, yawancin abubuwan da aka tsara sune samfuran barasa guda ɗaya ko na hadaddun barasa, amintaccen barasa, acetate da sauran albarkatun sinadarai.Idan aka kwatanta da sauran nau'ikan siminti iri ɗaya, diethyl barasa monoisopropyl barasa amine (DEIPA) yana da babban fa'ida wajen haɓaka haɓakar niƙa, ceton kuzari da rage yawan amfani da haɓaka ƙarfin siminti.
Hanyar samarwa
1.The kira na monoisopropanolamine (DEIPA) yana da uku main hanyoyi: na farko, da dauki kira na ammonia tare da ethylene oxide (EO) da propylene oxide (PO);
Na biyu, an samo shi ta hanyar amsawar MIPA da EO.Na uku, an haɗa shi daga diethanolamine (DEA) da PO.
2.Amonia da epoxy olefin dauki hanya
Wannan hanya amsa ce ta matakai uku.Ammoniya yana amsawa tare da EO don samar da ethanolamine, diethanolamine da triethanolamine.An haɗa masu amsawa tare da PO, kuma ana samun samfuran manufa bayan tsarkakewa.Ko, ammonia yana amsawa tare da PO don samar da monoisopropanolamine, diisopropanolamine da triisopropanolamine, kuma an haɗa reactant tare da EO, kuma ana samun samfurin da aka yi niyya bayan tsarkakewa.
3.DEA hanya
Wannan hanya tana amfani da amsawar DEA da PO don samar da abin da ake nufi DEIPA.Amfanin wannan hanyar ita ce saurin amsawa yana da sauri, zaɓin halayen halayen yana da girma, kuma samar da albarkatun ƙasa ya isa kuma barga.Ayyukan mu na DEIPA, a halin yanzu, duk suna amfani da wannan hanya, amma akwai bambanci a cikin samar da masana'anta ko bututun mai, a cikin samfurin isomer da kwanciyar hankali.
