Diethylenetriamine CAS:111-40-0

nature
Yellow hygroscopic transparent viscous liquid ine pungent ammonia hwema, inobvira uye yakasimba alkaline. Soluble mumvura, acetone, benzene, ether, methanol, etc., isinganyunguriki mun-heptane, uye inoita corrosive kumhangura nemaaroyi ayo. Kunyungudika -35 ℃. Boiling point 207 ℃. Relative density o. 9586. Flash point 94℃. Refractive index 1. 4810. Ichi chigadzirwa chine reactivity yeamine yechipiri uye inopindirana nyore nyore nemhando dzakasiyana-siyana. Zvigadzirwa zvayo zvine huwandu hwakawanda hwekushandisa.

Kugadzirira nzira
Inogona kuwanikwa neammoniation ye dichloroethane. 1,2-Ethyl chloride uye ammonia mvura inotumirwa mu-tubular reactor kuti iite hot-pressure ammoniation reaction pakupisa kwe150-250 ° C uye kudzvinyirira kwe392.3kPa. Mhinduro yemhinduro inogadziriswa nealkali kuti iwane yakasanganiswa yemahara amines, ayo anonamirwa achibvisa sodium chloride. Chigadzirwa chisina kuchena chinobva chanyungudutswa pasi pekumanikidzwa kwakaderedzwa uye chikamu chiri pakati pe195 ne215 ° C chinopindirwa kuti chiwane chigadzirwa chapera. Iyi nzira inogadzira pamwe chete ethylenediamine, triethylenetetramine, tetraethylenepentamine uye polyethylenepolyamine panguva imwe chete. Inogona kuwanikwa nekudzora tembiricha ye distillation tower kuti isvitse musanganiswa weamine uye kutora zvikamu zvakasiyana zvekuparadzanisa.

use
Ichi chigadzirwa chinonyanya kushandiswa seyekunyungudutsa uye organic synthesis yepakati, uye inogona kushandiswa kugadzira epoxy resin kurapa maajenti, gasi rekuchenesa (yekubvisa CO2), kuzora mafuta ekuwedzera, emulsifiers, emifananidzo makemikari, surfactants, uye machira ekupedzisa maajenti. , bepa enhancer, aminocarboxylic complexing agent, metal chelating agent, heavy metal hydrometallurgy uye cyanide-isina electroplating diffusion agent, brightener, uye synthetic ion exchange resin uye polyamide resin, nezvimwewo.
