Diethylenetriamine CAS: 111-40-0

chilengedwe
Yellow hygroscopic transparent viscous fluid ndi fungo lamphamvu la ammonia, loyaka komanso lamchere kwambiri. Amasungunuka m'madzi, acetone, benzene, ether, methanol, ndi zina zotero, osasungunuka mu n-heptane, komanso amawononga mkuwa ndi ma aloyi ake. Malo osungunuka -35 ℃. Malo otentha 207 ℃. Kuchulukana kwachibale o. 9586. Kung'anima mfundo 94 ℃. Refractive index 1. 4810. Mankhwalawa ali ndi reactivity ya amines yachiwiri ndipo amachitira mosavuta ndi mitundu yosiyanasiyana ya mankhwala. Zotulutsa zake zimakhala ndi ntchito zambiri.

Njira yokonzekera
Itha kupezeka ndi ammoniation ya dichloroethane. 1,2-Ethyl chloride ndi madzi ammonia amatumizidwa mu tubular riyakitala kuti achite kutentha-kukakamiza ammoniation reaction pa kutentha kwa 150-250 ° C ndi kuthamanga kwa 392.3kPa. The njira yothetsera ndi neutralized ndi alkali kupeza osakaniza ufulu amines, amene anaikira pamene kuchotsa sodium kolorayidi. Zopangira zopanda mafutazo zimasungunuka pansi pa kupanikizika kochepa ndipo gawo lapakati pa 195 ndi 215 ° C limadulidwa kuti lipeze mankhwala omalizidwa. Njira imeneyi imapanga ethylenediamine, triethylenetetramine, tetraethylenepentamine ndi polyethylenepolyamine nthawi yomweyo. Ikhoza kupezedwa poyang'anira kutentha kwa distillation tower kuti isungunuke kusakaniza kwa amine ndikuchotsa tizigawo tosiyanasiyana kuti tisiyanitse.

ntchito
Izi makamaka ntchito monga zosungunulira ndi organic kaphatikizidwe wapakatikati, ndipo angagwiritsidwe ntchito pokonzekera epoxy utomoni kuchiritsa wothandizila mpweya, oyeretsa mpweya (kuchotsa CO2), mafuta owonjezera mafuta, emulsifiers, zithunzi mankhwala, surfactants, ndi womaliza nsalu. , chowonjezera mapepala, aminocarboxylic complexing agent, metal chelating agent, heavy metal hydrometallurgy ndi cyanide-free electroplating diffusion agent, lightener, ndi synthetic ion exchange resin ndi polyamide resin, etc.
