Diethylenetriamine CAS: 111-40-0

xwm
Cov kua daj hygroscopic pob tshab viscous nrog pungent ammonia tsw, flammable thiab muaj zog alkaline. Yaj hauv dej, acetone, benzene, ether, methanol, thiab lwm yam, insoluble hauv n-heptane, thiab corrosive rau tooj liab thiab nws cov alloys. Melting point -35 ℃. Boiling point 207 ℃. Relative density o. 9586. Flash point 94 ℃. Refractive index 1. 4810. Cov khoom no muaj reactivity ntawm secondary amines thiab yooj yim reacts nrog ntau yam compounds. Nws cov derivatives muaj ntau yam kev siv.

Txoj kev npaj
Nws tuaj yeem tau los ntawm kev ua kom muaj ammoniation ntawm dichloroethane. 1,2-Ethyl chloride thiab ammonia dej raug xa mus rau hauv lub reactor tubular los ua qhov kub-siab ammoniation reaction ntawm qhov kub ntawm 150-250 ° C thiab qhov siab ntawm 392.3kPa. Cov tshuaj tiv thaiv yog neutralized nrog alkali kom tau txais cov amines dawb sib xyaw, uas tau concentrated thaum tshem tawm sodium chloride. Cov khoom nyoos ces raug distilled nyob rau hauv qhov txo qis siab thiab cov feem ntawm 195 thiab 215 ° C raug intercepted kom tau txais cov khoom tiav. Txoj kev no co-tsim ethylenediamine, triethylenetetramine, tetraethylenepentamine thiab polyethylenepolyamine tib lub sijhawm. Nws tuaj yeem tau txais los ntawm kev tswj qhov kub ntawm lub pej thuam distillation kom distill cov amine sib xyaw thiab intercepting cov feem sib txawv rau kev sib cais.

siv
Cov khoom no feem ntau yog siv ua cov kuab tshuaj thiab cov organic synthesis intermediate, thiab tuaj yeem siv los npaj cov neeg sawv cev epoxy resin curing, cov roj purifiers (rau CO2 tshem tawm), cov roj nplua nyeem ntxiv, emulsifiers, cov tshuaj photographic, surfactants, thiab cov neeg sawv cev tiav ntaub. , cov ntawv txhim kho, aminocarboxylic complexing agent, cov neeg sawv cev hlau chelating, cov hlau hnyav hydrometallurgy thiab cyanide-free electroplating diffusion agent, brightener, thiab cov khoom siv hluavtaws ion pauv thiab polyamide resin, thiab lwm yam.
