DI METHYL ETHANOLAMINE (DMEA)

DI METHYL ETHANOLAMINE, bụ ngwakọta organic, usoro kemịkalụ C5H13NO2, maka mmiri mmiri na-enweghị agba ma ọ bụ ọchịchịrị na-acha odo odo, nwere ike iji mmiri, mmanya na-egbu egbu, soluble na ether.A na-ejikarị eme ihe dị ka emulsifier na acid gas absorbent, onye na-ahụ maka njikwa acid, polyurethane foam catalyst, nke a na-ejikwa dị ka ọgwụ antitumor dị ka nitrogen mọstad hydrochloride etiti.

Njirimara:Ngwaahịa a nwere isi amonia na-enweghị agba ma ọ bụ mmiri mmiri na-acha odo odo, na-ere ọkụ.Enwere ike ime ya na mmiri, ethanol, benzene, ether na acetone.Njupụta njikọ 0.8879, ebe esi 134,6 ℃.Ebe oyi - 59. O℃.Ebe mgbanye ọkụ 41 ℃.Ebe Flash ( iko mepere emepe) 40 ℃.Viscosity (20 ℃) ​​3.8mPa.s.Ntụgharị ntụgharị 1.4296.

Usoro nkwadebe:

1.Ethylene oxide usoro site dimethylamine na ethylene oxide amonia, site distillation, distillation, akpịrị ịkpọ nkụ.

2.Chloroethanol usoro nwetara site saponification nke chloroethanol na alkali na-emepụta ethylene oxide, na mgbe ahụ synthesized na dimethylamine.

 Ngwa nke DMEA:

Ọrụ catalytic nke N, N-dimethylethanolamine DMEA dị ala, ọ na-enwekwa mmetụta dị nta na ịrị elu ụfụfụ na mmeghachi omume gel, ma dimethylethanolamine DMEA nwere alkalinity siri ike, nke nwere ike imebi ọnụọgụ ahụ n'ime ihe ndị na-emepụta ụfụfụ Acids, karịsịa ndị nọ na isocyanates. , yabụ na-ejigide amines ndị ọzọ na sistemụ.Ọrụ dị ala na ikike nkwụsị dị elu nke dimethylethanolamine DMEA na-arụ ọrụ dị ka ihe nchekwa na ọ bara uru karịsịa mgbe ejikọtara ya na triethylenediamine, nke mere na enwere ike nweta ọnụego mmeghachi omume achọrọ na obere mkpokọta triethylenediamine.

Dimethylethanolamine (DMEA) nwere ọtụtụ ihe eji eme ihe, dị ka: dimethylethanolamine DMEA nwere ike iji kwadebe mkpuchi mmiri na-edozi mmiri;dimethylethanolamine DMEA bụkwa ihe eji eme ihe maka dimethylaminoethyl methacrylate, nke a na-eji akwadebe ihe mgbochi static, ntụ oyi ala, ihe ndị na-eduzi, ihe mgbakwunye akwụkwọ na flocculants;A na-ejikwa dimethylethanolamine DMEA na ndị na-ahụ maka ọgwụgwọ mmiri iji gbochie nrụrụ ọkụ.

Na ụfụfụ polyurethane, dimethylethanolamine DMEA bụ onye na-emekọ ihe na onye na-eme ihe ike, na dimethylethanolamine DMEA nwere ike iji mee ihe na-emepụta ụfụfụ polyurethane na-agbanwe agbanwe na ụfụfụ polyurethane siri ike.Enwere otu hydroxyl na molecule nke dimethylethanolamine DMEA, nke nwere ike imeghachi omume na otu isocyanate, ya mere, dimethylethanolamine DMEA nwere ike jikọta ya na ngwongwo polymer, ọ gaghị adị ka triethylamine.
