Diethyl monoisopropanolamine
Taw qhia
Diethyl cawv monoisopropanolamine yog ib yam ntawm cov organic teeb meem, tshuaj formula C7H17O3N, tsis muaj xim los yog lub teeb daj pob tshab nrog ammonia tsw stimulated viscous kua, ruaj khov ntawm chav tsev kub thiab siab.Diethyl cawv monoisopropanolamine yog ib hom tshiab ntawm ntsuab sib tsoo cov khoom siv, uas muaj kev sib tsoo pom tseeb, thiab yog siv dav hauv kev sib tsoo cov cement.
(1) Diethanolamine monoisopropyl olamine yog tsuas yog siv rau hauv surfactants, dav siv nyob rau hauv tshuaj raw cov ntaub ntawv, pigments, tshuaj, tsev cov ntaub ntawv thiab lwm yam teb, nyob rau hauv cement additives, cov khoom tu tawv nqaij thiab textile softener ntau daim ntaub ntawv.
(2) Tam sim no, nyob rau hauv lub tshav pob zeb sib tsoo AIDS, feem ntau ntawm cov formulations yog ib leeg los yog compound khoom ntawm cawv, cawv amine, acetate thiab lwm yam tshuaj raw khoom.Piv nrog rau lwm cov cement additives zoo sib xws, diethyl cawv monoisopropyl cawv amine (DEIPA) muaj txiaj ntsig zoo hauv kev txhim kho kev sib tsoo, kev txuag hluav taws xob thiab kev txo qis thiab txhim kho cov cement zog.
Txoj kev tsim khoom
1.Lub synthesis ntawm monoisopropanolamine (DEIPA) muaj peb txoj hauv kev: thawj, cov tshuaj tiv thaiv synthesis ntawm ammonia nrog ethylene oxide (EO) thiab propylene oxide (PO);
Qhov thib ob, nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm MIPA thiab EO.Thib peb, nws yog synthesized los ntawm diethanolamine (DEA) thiab PO.
2.Ammonia thiab epoxy olefin cov tshuaj tiv thaiv txoj kev
Txoj kev no yog peb-theem series cov tshuaj tiv thaiv.Ammonia reacts nrog EO los tsim ib qho ethanolamine, diethanolamine thiab triethanolamine.Cov reactants yog synthesized nrog PO, thiab lub hom phiaj cov khoom tau txais tom qab purification.Los yog, ammonia reacts nrog PO los tsim monoisopropanolamine, diisopropanolamine thiab triisopropanolamine, thiab cov reactant yog synthesized nrog EO, thiab lub hom phiaj cov khoom yog tau tom qab purification.
3.DEA txoj kev
Txoj kev no siv DEA thiab PO cov tshuaj tiv thaiv los tsim cov hom phiaj DEIPA.Qhov kom zoo dua ntawm txoj kev no yog tias cov tshuaj tiv thaiv tus nqi nrawm, kev xaiv ntawm cov tshuaj tiv thaiv yog siab, thiab cov khoom siv raw khoom txaus thiab ruaj khov.Peb cov khoom siv DEIPA, tam sim no, txhua tus siv txoj hauv kev no, tab sis muaj qhov sib txawv ntawm cov nroj tsuag ntau lawm lossis cov tshuaj yeeb dej caw, hauv cov khoom isomer thiab kev ruaj ntseg zoo.
