DI METHYL ETHANOLAMINE,ke motsoako oa lintho tse phelang, foromo ea lik'hemik'hale C5H13NO2, bakeng sa mokelikeli o mosehla o se nang mebala kapa o lefifi, o ka tsoakana le metsi, joala, hanyenyane ho qhibiliha ka ether.Haholo-holo e sebelisoa e le emulsifier le acid e monyang khase, acid base control agent, polyurethane foam catalyst, hape e sebelisoa e le lithethefatsi tsa antitumor tse kang nitrogen mosetareta hydrochloride mahareng.
Thepa:Sehlahisoa sena se na le monko oa ammonia o se nang 'mala kapa o mosehla, o tukang.E ka kopanngoa le metsi, ethanol, benzene, ether le acetone.Boima ba kamano 0.8879, ntlha e belang 134,6 ℃.Leqhoa - 59. O℃.Sebaka sa ho khantša 41℃.Ntlha ea Flash (kopi e bulehileng) 40 ℃.Viscosity (20 ℃) 3.8mPa.s.Refractive index 1.4296.
Mokhoa oa ho itokisa:
1. Ts'ebetso ea ethylene oxide ka dimethylamine le ethylene oxide ammonia, ka ho senya, ho senya, ho felloa ke metsi.
Ts'ebetso ea 2.Chloroethanol e fumanoa ka saponification ea chloroethanol le alkali ho hlahisa ethylene oxide, ebe e etsoa ka dimethylamine.
Likopo tsa DMEA:
Ts'ebetso ea catalytic ea N, N-dimethylethanolamine DMEA e tlase haholo, 'me ha e na phello e nyane ho phatloheng ha foam le karabelo ea gel, empa dimethylethanolamine DMEA e na le alkalinity e matla, e ka fokotsang palo ea likarolo tse phoroselang tsa Acids, haholo-holo tse isocyanate. , kahoo boloka li-amine tse ling tsamaisong.Ts'ebetso e tlase le bokhoni bo phahameng ba ho se nke lehlakore ba dimethylethanolamine DMEA e sebetsa e le buffer mme e na le molemo haholo ha e sebelisoa hammoho le triethylenediamine, e le hore sekhahla sa karabelo se lakatsehang se ka finyelloa ka likhahla tse tlase tsa triethylenediamine.
Dimethylethanolamine (DMEA) e na le mefuta e mengata ea tšebeliso, e kang: dimethylethanolamine DMEA e ka sebelisoa ho lokisetsa liaparo tse nang le metsi a mangata;dimethylethanolamine DMEA e boetse e le thepa e tala bakeng sa dimethylaminoethyl methacrylate, e sebelisetsoang ho lokisa li-anti-Static agents, li-conditioner tsa mobu, lisebelisoa tsa conductive, li-additives tsa pampiri le li-flocculants;dimethylethanolamine DMEA e boetse e sebelisoa ho li-agent tsa phekolo ea metsi ho thibela ho bola ha boiler.
Ka polyurethane foam, dimethylethanolamine DMEA ke co-catalyst le catalyst reactive, 'me dimethylethanolamine DMEA e ka sebelisoa ha ho etsoa flexible polyurethane foam le rigid polyurethane foam.Ho na le sehlopha sa hydroxyl molek'hule ea dimethylethanolamine DMEA, e ka sebetsanang le sehlopha sa isocyanate, kahoo dimethylethanolamine DMEA e ka kopanngoa le molek'hule ea polymer, 'me e ke ke ea e-ba e tsitsitseng joaloka triethylamine.
Sephutheloana sa sehlahisoa:U sebelisa sephutheloana sa meropa ea tšepe, boima ba nete ba 180kg ka moropa ka mong.Boloka sebakeng se phodileng le se nang le moya.Boloka le ho tsamaisa ho latela lik'hemik'hale tse tukang le tse chefo.
