Diethyl monoisopropanolamine
Mawu Oyamba
Diethyl mowa monoisopropanolamine ndi mtundu wa zinthu organic, mankhwala chilinganizo C7H17O3N, colorless kapena kuwala chikasu mandala ndi ammonia kukoma analimbikitsa viscous madzi, khola firiji ndi mavuto.Diethyl mowa monoisopropanolamine ndi mtundu watsopano wa zinthu zobiriwira akupera thandizo, amene ali n'zoonekeratu akupera thandizo kwenikweni, ndipo chimagwiritsidwa ntchito simenti akupera thandizo.
(1) Diethanolamine monoisopropyl olamine imagwiritsidwa ntchito kwambiri muzopangira zinthu, zomwe zimagwiritsidwa ntchito kwambiri muzopangira mankhwala, inki, mankhwala, zomangira ndi madera ena, muzowonjezera za simenti, zinthu zosamalira khungu ndi zofewa za nsalu zambiri.
(2) Pakali pano, pa gawo la AIDS pogaya simenti, ambiri mwa mankhwala ndi limodzi kapena pawiri mankhwala mowa, mowa amine, acetate ndi zina mankhwala zipangizo.Poyerekeza ndi zowonjezera zina zofananira za simenti, diethyl alcohol monoisopropyl alcohol amine (DEIPA) ili ndi zabwino zambiri pakuwongolera bwino ugayi, kupulumutsa mphamvu ndi kuchepetsa kugwiritsa ntchito komanso kukulitsa mphamvu ya simenti.
Njira Yopangira
1.Kuphatikizika kwa monoisopropanolamine (DEIPA) kuli ndi njira zazikulu zitatu: choyamba, kaphatikizidwe ka ammonia ndi ethylene oxide (EO) ndi propylene oxide (PO);
Chachiwiri, amapangidwa ndi zochita za MIPA ndi EO.Chachitatu, amapangidwa kuchokera ku diethanolamine (DEA) ndi PO.
2.Amonia ndi njira ya epoxy olefin reaction
Njirayi ili ndi magawo atatu.Ammonia imakhudzidwa ndi EO kupanga ethanolamine, diethanolamine ndi triethanolamine.Ma reactants amapangidwa ndi PO, ndipo zinthu zomwe zimayang'aniridwa zimapezedwa pambuyo pa kuyeretsedwa.Kapena, ammonia amachitira ndi PO kuti apange monoisopropanolamine, diisopropanolamine ndi triisopropanolamine, ndipo reactant imapangidwa ndi EO, ndipo chinthu chandamale chimapezedwa pambuyo pa kuyeretsedwa.
3.DEA njira
Njirayi imagwiritsa ntchito DEA ndi PO reaction kuti ipange DEIPA yomwe mukufuna.Ubwino wa njirayi ndikuti kuchuluka kwazomwe zimachitika mwachangu, kusankhidwa kwa zomwe zimachitika ndikwambiri, komanso kupereka kwazinthu zopangira ndikwanira komanso kokhazikika.Kupanga kwathu kwa DEIPA, pakali pano, onse amagwiritsa ntchito njira iyi, koma pali kusiyana pakati pa zopangira kapena kachitidwe ka mapaipi, mu isomer yazinthu komanso kukhazikika kwabwino.
