Diethylenetriamine CAS: 111-40-0

xwm
Daj hygroscopic pob tshab viscous kua nrog pungent ammonia tsw, flammable thiab muaj zog alkaline. Soluble nyob rau hauv dej, acetone, benzene, ether, methanol, thiab lwm yam., insoluble nyob rau hauv n-heptane, thiab corrosive rau tooj liab thiab nws alloys. Melting point -35 ℃. Kub taw tes 207 ℃. kwv tij density o. 9586. Flash point 94 ℃. Refractive index 1. 4810. Cov khoom no muaj cov reactivity ntawm theem nrab amines thiab yooj yim reacts nrog ntau yam sib txuas. Nws cov derivatives muaj ntau yam kev siv.

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

siv
Cov khoom no yog siv los ua cov kuab tshuaj thiab cov organic synthesis nruab nrab, thiab tuaj yeem siv los npaj epoxy resin curing agents, gas purifiers (rau CO2 tshem tawm), lubricating oil additives, emulsifiers, photographic chemicals, surfactants, and fabric finishing agents. , ntawv enhancer, aminocarboxylic complexing tus neeg saib xyuas, hlau chelating tus neeg saib xyuas, hnyav hlau hydrometallurgy thiab cyanide-dawb electroplating diffusion tus neeg saib xyuas, brightener, thiab hluavtaws ion pauv resin thiab polyamide resin, thiab lwm yam.
