Triethanolamine Triethanolamine inozivikanwawo semamine matatu ekuwedzera uye triethanol. Imvura isina ruvara ine hwema hweammonia. Inonwisa mvura nyore nyore uye inoshanduka kuita brown kana yaiswa mumhepo kana yaiswa muchiedza. Inoshanduka kuita crystal ye cubic isina ruvara kana yero yakajeka pakupisa kwakaderera.

Hunhu hwemakemikari:

Imvura isina ruvara, inoonekera uye inonamira patembiricha yemumba. Iine hunyoro, ine hwema hweammonia, ine alkaline, uye inogumbura. Nzvimbo yekunyunguduka ndeye 21.2℃, nzvimbo yekufashaira ndeye 360℃, nzvimbo yekufuratira ndeye 193℃, iyo Chemicalbook relative density (d420) ndeye 1.1242, uye iyo refractive index (nD20) ndeye 1.4852. Inosanganiswa mumvura, ethanol uye acetone, inonyunguduka zvishoma mu ether, benzene uye carbon tetrachloride.

Chinangwa:

Inoshandiswa semvura yakachena yekubvisa carbon dioxide kana hydrogen sulfide kubva mugasi. MaEsters anoumbwa pakati petriethanolamine nemafuta akawanda anoshandiswa zvakanyanya semasepa, maemulsifier, mahumectants uye mafuta, uye anoshandiswawo mukugadzira mabaram ekushongedza. Triethanolamine inoshandiswawo semushonga wekuchengetedza, wekudzivirira mvura, wekuongorora, uye wekugadzirisa. Inogona kushandiswa semushandi wekuita kuti nitrile rabha iite polymerization, uye inogonawo kushandiswa semushonga wekusimbisa uye wekusimbisa mafuta newakisi, uye wekusimbisa machira mumamiriro ezvinhu ane acidic. Ndiyo imwe yezvikamu zveoiri yekutenderera yepolyester nedzimwe fiber dzekugadzira.

nzira yekugadzira

Inofanira kupinza ethylene oxide nemvura yeammonia mureactor, uye kuita condensation reaction patembiricha yereaction ye30-40°C uye reaction pressure ye70.9-304kPa kugadzira mhinduro yakasanganiswa yemono-, di-, uye triethanolamine, iyo inodziiswa pa90-120°C. Mushure mekushaya mvura uye kuzara, inotumirwa kutatu vacuum Chemicalbook distillation towers kuti iite vacuum distillation. Zvidimbu zvinobatwa zvichienderana nenzvimbo dzakasiyana dzekubikira kuti zviwane monoethanolamine, diethanolamine uye triethanolamine zvigadzirwa zvakapedzwa zvine kuchena kwe99%. Munguva yereaction process, kana chikamu cheethylene oxide chikawedzerwa, huwandu hwekugadzirwa kwedi- uye triethanolamine huchawedzera, izvo zvinogona kuwedzera goho redi- uye triethanolamine.
