Ko te DI METHYL ETHANOLAMINE, he matū waro, ko te tauira matū C5H13NO2, mō te wai hinuhinu kore tae, kowhai pouri rānei, ka taea te whakaranu ki te wai, ki te waipiro, he paku wairewa ki te ether. E whakamahia whānuitia ana hei emulsifier me te mimiti hau waikawa, hei kaiwhakahaere turanga waikawa, hei whakakorikori pahuka polyurethane, e whakamahia ana hoki hei rongoā ārai pukupuku pērā i te takawaenga hauota māti hauwaioraora.
Ngā Āhuatanga:He kakara haukini tēnei hua, he wai kore tae, he wai kōwhai rānei, he mura. Ka taea te whakaranu ki te wai, te etanoru, te benzene, te etera me te acetone. Te mātotoru whanaunga 0.8879, te ira kohua 134,6℃. Te ira tio – 59.0℃. Te ira mura 41℃. Te ira mura (kapu tuwhera) 40℃. Te matotoru (20℃) 3.8mPa.s. Te taupū whakaata 1.4296.
Tikanga whakarite:
1. Te tukatuka i te waikura ethylene mā te dimethylamine me te haukini waikura ethylene, mā te whakatōtō, te whakatōtō, te whakamaroke.
2. Ka whiwhihia te tukanga chloroethanol mā te saponification o te chloroethanol me te alkali hei whakaputa i te ethylene oxide, kātahi ka hangaia ki te dimethylamine.
Ngā tono o te DMEA：
He tino iti te kaha whakaterenga o te N,N-dimethylethanolamine DMEA, ā, he iti noa iho tōna pānga ki te pikinga o te pahuka me te tauhohenga ira, engari he kaha te kawakore o te dimethylethanolamine DMEA, ka taea te whakakore i te iti o te huka i roto i ngā wāhanga huka. Ko ngā waikawa, inā koa ko ērā i roto i ngā isocyanates, ka pupuri i ētahi atu amine i roto i te pūnaha. Ko te iti o te mahi me te kaha whakakorenga teitei o te dimethylethanolamine DMEA ka mahi hei parepare, ā, he tino painga ina whakamahia tahitia me te triethylenediamine, kia taea ai te whakatutuki i te tere tauhohenga e hiahiatia ana me te iti o te kukū o te triethylenediamine.
He whānuitia ngā whakamahinga o te Dimethylethanolamine (DMEA), pēnei i: Ka taea te whakamahi i te dimethylethanolamine DMEA hei hanga i ngā paninga wairewa-wai; he rauemi mata anō hoki te dimethylethanolamine DMEA mō te dimethylaminoethyl methacrylate, e whakamahia ana hei hanga i ngā kaihoko anti-Static, ngā whakangawari oneone, ngā rauemi kawe hiko, ngā tāpiringa pepa me ngā flocculants; ka whakamahia anō hoki te dimethylethanolamine DMEA i roto i ngā kaihoko maimoatanga wai hei ārai i te waikura o ngā poihau.
I roto i te pahuka polyurethane, he kaiwhakaoho tahi te dimethylethanolamine DMEA, ā, he kaiwhakaoho tauhohe, ā, ka taea te whakamahi i te dimethylethanolamine DMEA i roto i te hanganga o te pahuka polyurethane ngāwari me te pahuka polyurethane pakari. He rōpū hydroxyl kei roto i te ngota ngota o te dimethylethanolamine DMEA, ka taea te tauhohe ki te rōpū isocyanate, nō reira ka taea te whakakotahi i te dimethylethanolamine DMEA me te ngota polymer, ā, e kore e tino pōrearea pērā i te triethylamine.
Te takai hua:He takai rino te ipu, ko te taumaha kupenga he 180kg mō ia ipu. Penapena ki te wāhi hauhautanga, hauhautanga hoki. Penapenahia, ā, kawehia kia rite ki ngā matū mura me ngā matū paitini.
