Diethylenetriamine CAS:111-40-0

zvakasikwa
Mvura yero inopenya, yakajeka, ine hwema hweammonia, inobvira uye ine alkaline yakasimba. Inonyungudika mumvura, acetone, benzene, ether, methanol, nezvimwewo, hainyungudike mu n-heptane, uye inoparadza mhangura ne alloys dzayo. Nzvimbo yekunyungudika -35℃. Nzvimbo yekufashaira 207℃. Kuwanda kwehuwandu o. 9586. Nzvimbo yekupenya 94℃. Refractive index 1. 4810. Chigadzirwa ichi chine reactivity yesecondary amines uye chinopindura zviri nyore nemarudzi akasiyana-siyana emakomputa. Zvibereko zvacho zvine mashandisirwo akasiyana-siyana.

Nzira yekugadzirira
Inogona kuwanikwa nekushandisa dichloroethane ammonia. 1,2-Ethyl chloride nemvura yeammonia zvinotumirwa mu tubular reactor kuti zviite hot-pressure ammoniation reaction patembiricha ye150-250°C uye pressure ye392.3kPa. Mhinduro yacho inobviswa nealkali kuti pave nema mixed free amines, ayo anosanganiswa panguva yekubvisa sodium chloride. Chigadzirwa chisina kuchena chinozobviswa ne pressure yakaderera uye fraction iri pakati pe195 ne215°C inobviswa kuti pave ne finish product. Iyi nzira inogadzira ethylenediamine, triethylenetetramine, tetraethylenepentamine uye polyethylenepolyamine panguva imwe chete. Inogona kuwanikwa nekudzora tembiricha ye distillation tower kuti inyungudise musanganiswa weamine uye kubata fractions dzakasiyana kuti dziparadzaniswe.

shandisa
Chigadzirwa ichi chinonyanya kushandiswa semusanganiswa wezvinhu zvinonyungudutsa uye organic synthesis, uye chinogona kushandiswa kugadzira epoxy resin curing agents, gas purifiers (yekubvisa CO2), lubricating oil additives, emulsifiers, photographic chemicals, surfactants, uye jira finishing agents. , paper enhancer, aminocarboxylic complexing agent, metal chelating agent, heavy metal hydrometallurgy and cyanide-free electroplating diffusion agent, brightener, uye synthetic ion exchange resin uye polyamide resin, nezvimwewo.
