DI METHYL ETHANOLAMINE,he pūhui waro, tātai matū C5H13NO2, mo te wai hinuhinu kore tae, pouri kowhai ranei, ka taea te micible ki te wai, te waipiro, te wairewa paku ki te etera.Te nuinga whakamahia rite emulsifier me te waikawa hau absorbent, waikawa turanga māngai mana, polyurethane pahuka i whakakōkī, whakamahia hoki rite taero antitumor pērā i hauota pua nani hydrochloride takawaenga.
Āhuatanga:Ko tenei hua he haukinia kakara kore tae, he wai kowhai ranei, ka mura.Ka taea te whakauru ki te wai, te waihano, te benzene, te ether me te acetone.Kiato pātahi 0.8879, ira kohua 134,6 ℃.Te waahi mīti – 59. O℃.Ira mura 41℃.Ira hiko (kapu tuwhera) 40 ℃.Viscosity (20 ℃) 3.8mPa.s.Taupū Reractive 1.4296.
Tikanga takahanga:
1.Ethylene oxide te tukanga na te dimethylamine me te ethylene oxide ammonia, na roto i te whakakore, te whakakore, te whakaheke.
Ko te tukanga 2.Chloroethanol ka whiwhi i te saponification o te chloroethanol me te alkali ki te whakaputa i te ethylene oxide, katahi ka whakahiatotia ki te dimethylamine.
Nga tono a DMEA：
Ko te mahi catalytic o N,N-dimethylethanolamine DMEA he iti rawa, he iti te paanga ki te piki o te pahuka me te tauhohenga ra, engari he kaha te kawakore o te dimethylethanolamine DMEA, ka taea te whakakore i te nui o nga waahanga o te hukahuka waikawa, ina koa ko nga mea kei roto i te isocyanates. , na reira ka mau etahi atu amine i roto i te punaha.Ko te iti o te ngohe me te kaha whakaheke teitei o te dimethylethanolamine DMEA ka mahi hei parepare me te tino painga ina whakamahia me te triethylenediamine, kia taea ai te tere tauhohenga e hiahiatia ana me te iti o te kukume o te triethylenediamine.
Ko te Dimethylethanolamine (DMEA) he maha nga whakamahinga, penei: ka taea te whakamahi i te dimethylethanolamine DMEA ki te whakarite i nga paninga wai-diluted;Ko te dimethylethanolamine DMEA ano he rauemi mata mo te dimethylaminoethyl methacrylate, e whakamahia ana hei whakarite i nga anti- Static agents, conditioners soil, conductive material, paper additives and flocculants;Ka whakamahia ano te dimethylethanolamine DMEA i roto i nga kaihoko maimoatanga wai hei aukati i te pirau o te kohua.
I roto i te pahuka polyurethane, ko te dimethylethanolamine DMEA he whakakorikori tahi me te whakakorikori reactive, a ka taea te whakamahi dimethylethanolamine DMEA i roto i te hanga o te pahuka polyurethane ngawari me te pahuka polyurethane pakari.He roopu hydroxyl kei roto i te ngota ngota o te dimethylethanolamine DMEA, ka taea te tauhohe me te roopu isocyanate, na reira ka taea te whakakotahi te dimethylethanolamine DMEA me te ngota ngota polymer, a ka kore e rite ki te triethylamine.
tākai hua:Ma te whakamahi i te takai pahū rino, te taumaha kupenga 180kg mo ia pahū.Rokiroki ki te waahi hauhautanga me te hau.Rokiroki me te kawe i runga i nga matū mura me te paitini.
