CAS tus naj npawb ntawm triethylenetetramine yog 112-24-3, cov mis molecular yog C6H18N4, thiab nws yog ib lub teeb daj kua uas muaj zog hauv paus thiab nruab nrab viscosity. Ntxiv rau kev siv los ua cov kuab tshuaj, triethylenetetramine kuj tseem siv rau hauv kev tsim cov epoxy resin curing agents, hlau chelating agents, thiab hluavtaws polyamide resins thiab ion exchange resins.

lub cev muaj zog
Muaj zog alkaline thiab cov kua qaub daj daj, nws cov volatility qis dua li ntawm diethylenetriamine, tab sis nws cov khoom zoo sib xws. Kub taw tes 266-267 ° C (272 ° C), 157 ° C (2.67kPa), khov point 12 ° C, txheeb ze ntom ntom (20, 20 ° C) 0.9818, refractive index (nD20) 1.4971, flash point 143 ° C , auto-ignition point 338 ° C. Soluble hauv dej thiab ethanol, me ntsis soluble hauv ether. Flamable. Tsawg volatility, muaj zog hygroscopicity thiab muaj zog alkaline. Nws tuaj yeem nqus cov pa roj carbon dioxide hauv huab cua. Combustible, muaj kev pheej hmoo ntawm hlawv thaum raug qhib nplaim taws thiab cua sov. Nws muaj corrosive heev thiab tuaj yeem ua rau cov tawv nqaij thiab cov mucous membranes, qhov muag thiab ua pa, thiab ua rau tawv nqaij ua xua, bronchial hawb pob thiab lwm yam tsos mob.

tshuaj muaj zog
combustion (decomposition) cov khoom: suav nrog tshuaj lom nitrogen oxides.

Contraindications: acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, txiv neej anhydride, triisobutyl txhuas.

Muaj zog Alkali: Reacts nyob rau hauv kev sib cuag nrog oxidants muaj zog, ua rau hluav taws kub thiab tawg txaus ntshai. Reacts nyob rau hauv kev sib cuag nrog nitrogen tebchaw thiab chlorinated hydrocarbons. Reacts nrog acid. Tsis sib haum nrog cov amino tebchaw, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, cawv, ethylene glycol, phenols, cresols, thiab caprolactam daws. Reacts nrog nitrocellulose. Nws kuj yog incompatible nrog acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, thiab triisobutyl txhuas. Corrodes tooj liab, tooj liab alloys, cobalt thiab nickel.

Siv
1. Siv raws li chav kub curing tus neeg sawv cev rau epoxy resin;

2. Siv ua cov organic synthesis, dye intermediates thiab cov kuab tshuaj;

3. Siv rau hauv kev tsim cov polyamide resins, ion exchange resins, surfactants, lubricant additives, gas purifiers, thiab lwm yam.;

4. Siv raws li tus neeg sawv cev hlau chelating, cyanide-dawb electroplating diffusing tus neeg saib xyuas, roj hmab auxiliary, brightening agent, detergent, dispersing agent, thiab lwm yam.;

5. Siv los ua tus neeg saib xyuas complexing, dehydrating tus neeg saib xyuas rau alkaline roj, ntaub xov xov thiab hluavtaws raw khoom rau ion exchanger resin thiab polyamide resin;

6. Siv ua vulcanizing tus neeg sawv cev rau fluororubber.

Txoj kev tsim khoom
Nws txoj kev tsim khoom yog dichloroethane amination method. Cov dej 1,2-dichloroethane thiab ammonia raug xa mus rau hauv lub tubular reactor rau kub-nias amoniation ntawm qhov kub ntawm 150-250 ° C thiab lub siab ntawm 392.3 kPa. Cov tshuaj tiv thaiv yog neutralized nrog alkali kom tau cov amine dawb sib xyaw, uas yog concentrated kom tshem tawm sodium chloride, ces cov khoom crude yog distilled nyob rau hauv lub siab txo, thiab cov feem ntawm 195-215 ° C. yog intercepted kom tau cov khoom tiav. Txoj kev no ib txhij co-tsim ethylenediamine; diethylenetriamine; tetraethylenepentamine thiab polyethylenepolyamine, uas tuaj yeem tau txais los ntawm kev tswj xyuas qhov kub thiab txias ntawm cov pej thuam rectifying kom distilled cov amine sib tov, thiab cuam tshuam cov feem sib txawv rau kev sib cais.
