DI METHYL ETHANOLAMINE, ni imvange y’ibinyabuzima, formula ya shimi C5H13NO2, ikoreshwa mu mazi adafite ibara cyangwa umuhondo wijimye, ishobora kuvangwa n’amazi, alcool, igashonga gato muri ether. Ikoreshwa cyane cyane nk’imvange n’imyuka ifata aside, igenzura aside, ifuro rya polyurethane, inakoreshwa nk’imiti irwanya kanseri nka azote mustard hydrochloride intermediate.
Imitungo:Iki gicuruzwa gifite impumuro ya amoniya idafite ibara cyangwa amazi y'umuhondo, ishobora gushya. Ishobora kuvangwa n'amazi, etanoli, benzene, eteri na asetone. Ubucucike bungana na 0.8879, ubushyuhe bungana na 134,6℃. Ubukonje bungana na 59. O℃. Ubushyuhe bungana na 41℃. Ubushyuhe bungana na 40℃. Ubushyuhe (20℃) 3.8mPa. s. Ubushyuhe bungana na 1.4296.
Uburyo bwo gutegura:
1.Inzira ya etileni okiside ikorwa na dimethylamine na etileni okiside ammonia, binyuze mu kuyungurura, kuyungurura, no kubura amazi.
2. Uburyo bwa Chloroethanol buboneka binyuze mu gukusanya chloroethanol na alkali kugira ngo bikore ethylene oxide, hanyuma bigakorwa hamwe na dimethylamine.
Imikoreshereze ya DMEA:
Imikorere ya N,N-dimethylethanolamine DMEA ni mike cyane, kandi nta ngaruka igira ku izamuka ry'ifuro n'imikorere ya gel, ariko dimethylethanolamine DMEA ifite alkalinity ikomeye, ishobora kugabanya neza ingano y'ibice bifuro. Acide, cyane cyane iziri muri isocyanates, bityo ikabika andi ma amine muri sisitemu. Imikorere mike n'ubushobozi bwinshi bwo kugabanya ibicurane bya dimethylethanolamine DMEA bikora nk'umuyoboro w'amazi kandi bigira akamaro cyane iyo bikoreshejwe hamwe na triethylenediamine, kugira ngo igipimo cyifuzwa cy'imikorere kibashe kugerwaho hamwe n'ingano nto ya triethylenediamine.
Dimethylethanolamine (DMEA) ifite uburyo bwinshi bwo kuyikoresha, nko: dimethylethanolamine DMEA ishobora gukoreshwa mu gutegura irangi rishobora gushonga mu mazi; dimethylethanolamine DMEA ni igikoresho fatizo cya dimethylaminoethyl methacrylate, ikoreshwa mu gutegura imiti irwanya imihindagurikire y'ikirere, imiti ifasha mu gutunganya ubutaka, ibikoresho biyobora amazi, inyongeramusaruro ku mpapuro n'imiti igabanya ubushyuhe; dimethylethanolamine DMEA ikoreshwa kandi mu miti itunganya amazi kugira ngo hirindwe ingese mu byuma bisukura amazi.
Muri polyurethane foam, dimethylethanolamine DMEA ni co-catalyst na reactive catalyst, kandi dimethylethanolamine DMEA ishobora gukoreshwa mu gukora polyurethane foam yoroshye na polyurethane foam ikomeye. Hari itsinda rya hydroxyl muri molekyuli ya dimethylethanolamine DMEA, ishobora gukorana na isocyanate group, bityo dimethylethanolamine DMEA ishobora guhuzwa na polymer molecule, kandi ntabwo izaba ihindagurika cyane nka triethylamine.
Gupfunyika ibicuruzwa:Ukoresheje ipaki y'icyuma, uburemere bungana na 180kg kuri buri ngoma. Bika ahantu hakonje kandi hahumeka umwuka. Bika kandi ubijyane hakurikijwe imiti ishobora gushya n'uburozi.
