Chaw tsim tshuaj paus Zoo Nqe DI METHYL ETHANOLAMINE (DMEA) CAS: 108-01-0
Synonyms
N, N-Dimethyl-2-hydroxyethylamine, 2-dimethylaminoethanol
Cov ntawv thov ntawm DMEA
Kev ua haujlwm catalytic ntawm N, N-dimethylethanolamine DMEA yog qhov tsawg heev, thiab nws muaj qhov cuam tshuam me ntsis ntawm cov npuas dej nce thiab cov tshuaj tiv thaiv gel, tab sis dimethylethanolamine DMEA muaj zog alkalinity, uas tuaj yeem ua rau cov kab mob zoo hauv cov khoom ua npuas dej, tshwj xeeb tshaj yog cov hauv isocyanates. , yog li khaws lwm cov amines hauv lub cev.Qhov kev ua haujlwm qis thiab muaj peev xwm ua kom tsis zoo ntawm dimethylethanolamine DMEA ua raws li qhov tsis muaj thiab yog qhov zoo tshwj xeeb tshaj yog thaum siv nrog triethylenediamine, kom qhov xav tau cov tshuaj tiv thaiv tuaj yeem ua tiav nrog qis qis ntawm triethylenediamine.
Dimethylethanolamine (DMEA) muaj ntau yam kev siv, xws li: dimethylethanolamine DMEA tuaj yeem siv los npaj cov dej-dilutable coatings;dimethylethanolamine DMEA kuj yog cov khoom siv raw rau dimethylaminoethyl methacrylate, uas yog siv los npaj cov tshuaj tiv thaiv zoo li qub, cov khoom siv hauv av, cov khoom siv hluav taws xob, cov ntawv ntxiv thiab flocculants;Dimethylethanolamine DMEA kuj tseem siv rau hauv cov tshuaj kho dej los tiv thaiv boiler corrosion.
Nyob rau hauv polyurethane ua npuas ncauj, dimethylethanolamine DMEA yog ib tug co-catalyst thiab ib tug reactive catalyst, thiab dimethylethanolamine DMEA yuav siv tau nyob rau hauv lub formulation ntawm saj zawg zog polyurethane ua npuas ncauj thiab nruj polyurethane ua npuas ncauj.Muaj ib pawg hydroxyl nyob rau hauv cov molecule ntawm dimethylethanolamine DMEA, uas tuaj yeem hnov mob nrog isocyanate pawg, yog li dimethylethanolamine DMEA tuaj yeem ua ke nrog cov khoom siv polymer, thiab nws yuav tsis hloov pauv li triethylamine.
