DI METHYL ETHANOLAMINE, ke motsoako oa tlhaho, foromo ea lik'hemik'hale C5H13NO2, bakeng sa mokelikeli o se nang 'mala kapa o mosehla o lefifi o nang le oli, o ka kopanngoa le metsi, joala, o qhibiliha hanyane ka har'a ether. Haholo-holo e sebelisoa e le emulsifier le e monyang khase ea asiti, sesebelisoa sa taolo ea motheo oa asiti, se thusang foam ea polyurethane, hape e sebelisoa e le lithethefatsi tse loantšang hlahala tse kang naetrojene mustard hydrochloride intermediate.
Thepa:Sehlahisoa sena se na le monko oa ammonia o se nang 'mala kapa mokelikeli o mosehla, o ka tukang. Se ka kopanngoa le metsi, ethanol, benzene, ether le acetone. Boima bo amanang 0.8879, ntlha e belang 134,6℃. Ntlha ea ho hoama - 59. O℃. Ntlha ea ho hotetsa 41℃. Ntlha ea ho bonesa (kopi e bulehileng) 40℃. Ho teteana (20℃) 3.8mPa. s. Letšoao la ho bonesa 1.4296.
Mokhoa oa ho lokisa:
1.Ts'ebetso ea ethylene oxide ke dimethylamine le ethylene oxide ammonia, ka ho qhibilihisa, ho qhibilihisa, ho felloa ke metsi 'meleng.
2.Ts'ebetso ea Chloroethanol e fumanoa ka ho kopanya chloroethanol le alkali ho hlahisa ethylene oxide, ebe e kopanngoa le dimethylamine.
Litšebeliso tsa DMEA：
Tšebetso ea catalytic ea N,N-dimethylethanolamine DMEA e tlase haholo, 'me ha e na phello e kholo ho phahama ha foam le karabelo ea gel, empa dimethylethanolamine DMEA e na le alkalinity e matla, e ka fokotsang ka katleho palo ea mesaletsa likarolong tse ntšang foam. Li-acid, haholo-holo tse ka har'a isocyanate, ka hona li boloka li-amine tse ling tsamaisong. Tšebetso e tlase le bokhoni bo phahameng ba ho fokotsa ba dimethylethanolamine DMEA li sebetsa e le buffer 'me li molemo haholo ha li sebelisoa hammoho le triethylenediamine, e le hore sekhahla se lakatsehang sa karabelo se ka finyelloa ka mahloriso a tlase a triethylenediamine.
Dimethylethanolamine (DMEA) e na le mefuta e mengata ea tšebeliso, joalo ka: dimethylethanolamine DMEA e ka sebelisoa ho lokisa lipekere tse qhibilihang ka metsi; dimethylethanolamine DMEA hape ke thepa e tala bakeng sa dimethylaminoethyl methacrylate, e sebelisetsoang ho lokisa li-anti-Static agents, li-conditioner tsa mobu, thepa e tsamaisang metsi, li-additives tsa pampiri le li-flocculant; dimethylethanolamine DMEA e boetse e sebelisoa li-agents tsa kalafo ea metsi ho thibela ho bola ha boiler.
Ka foam ea polyurethane, dimethylethanolamine DMEA ke co-catalyst le catalyst e arabelang, 'me dimethylethanolamine DMEA e ka sebelisoa ho etseng foam e tenyetsehang ea polyurethane le foam e thata ea polyurethane. Ho na le sehlopha sa hydroxyl molek'huleng ea dimethylethanolamine DMEA, e ka arabelang le sehlopha sa isocyanate, kahoo dimethylethanolamine DMEA e ka kopanngoa le molek'hule ea polymer, 'me e ke ke ea fetoha e feto-fetohang joalo ka triethylamine.
Sephutheloana sa sehlahisoa:U sebelisa sephutheloana sa teramo ea tšepe, boima ba eona ke 180kg ka teramo. Boloka sebakeng se pholileng le se nang le moea o kenang. Boloka 'me u e tsamaise ho latela lik'hemik'hale tse tukang le tse chefo.
