Hanyar shiri:
1.Ethylene oxide tsari ta dimethylamine da ethylene oxide ammonia, ta hanyar distillation, distillation, dehydration.
2.Chloroethanol tsari yana samuwa ta hanyar saponification na chloroethanol da alkali don samar da ethylene oxide, sa'an nan kuma hada da dimethylamine.
Aikace-aikace na DMEA:
Ayyukan catalytic na N, N-dimethylethanolamine DMEA yana da ƙasa sosai, kuma yana da ɗan tasiri akan hawan kumfa da gel dauki, amma dimethylethanolamine DMEA yana da alkalinity mai karfi, wanda zai iya kawar da adadin da aka gano a cikin abubuwan da ke cikin kumfa Acids, musamman ma wadanda ke cikin isocyanates. , don haka riƙe sauran amines a cikin tsarin.Ƙarƙashin ƙarancin aiki da babban ƙarfin neutralizing dimethylethanolamine DMEA yana aiki a matsayin buffer kuma yana da fa'ida musamman idan aka yi amfani da shi tare da triethylenediamine, ta yadda za'a iya samun ƙimar amsawar da ake so tare da ƙananan matakan triethylenediamine.
Dimethylethanolamine (DMEA) yana da amfani mai yawa, irin su: dimethylethanolamine DMEA za a iya amfani dashi don shirya suturar ruwa-dilutable;dimethylethanolamine DMEA kuma danyen abu ne na dimethylaminoethyl methacrylate, wanda ake amfani da shi don shirya magungunan anti-Static, kwandishan na ƙasa, kayan aiki, kayan ƙara takarda da flocculants;dimethylethanolamine DMEA kuma ana amfani dashi a cikin magungunan ruwa don hana lalacewar tukunyar jirgi.
A cikin kumfa polyurethane, dimethylethanolamine DMEA shine co-catalyst da mai kunnawa mai amsawa, kuma dimethylethanolamine DMEA za'a iya amfani dashi a cikin tsari na kumfa polyurethane mai sassauƙa da kumfa polyurethane mai ƙarfi.Akwai ƙungiyar hydroxyl a cikin kwayoyin dimethylethanolamine DMEA, wanda zai iya amsawa tare da ƙungiyar isocyanate, don haka dimethylethanolamine DMEA za a iya haɗuwa tare da kwayoyin polymer, kuma ba zai zama mai sauƙi kamar triethylamine ba.
Kunshin samfur:Yin amfani da marufi na baƙin ƙarfe, net nauyin 180kg kowace ganga.Ajiye a wuri mai sanyi da iska.Ajiye da jigilar kaya bisa ga sinadarai masu ƙonewa da masu guba.
