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

cov khoom siv lub cev
Muaj zog alkaline thiab cov kua daj uas muaj viscous me ntsis, nws qhov volatility qis dua li ntawm diethylenetriamine, tab sis nws cov khoom zoo sib xws. Boiling point 266-267 ° C (272 ° C), 157 ° C (2.67kPa), freezing point 12 ° C, relative density (20, 20 ° C) 0.9818, refractive index (nD20) 1.4971, flash point 143 ° C, auto-ignition point 338 ° C. Yaj hauv dej thiab ethanol, yaj me ntsis hauv ether. Flammable. Low volatility, muaj zog hygroscopicity thiab muaj zog alkaline. Tuaj yeem nqus cov pa roj carbon dioxide hauv huab cua. Hluav taws kub, muaj kev pheej hmoo ntawm kev hlawv thaum raug rau cov nplaim taws qhib thiab cua sov. Nws yog corrosive heev thiab tuaj yeem ua rau daim tawv nqaij thiab cov ntaub so ntswg mucous, qhov muag thiab txoj hlab pa, thiab ua rau daim tawv nqaij ua xua, bronchial hawb pob thiab lwm yam tsos mob.

cov khoom siv tshuaj lom neeg
Cov khoom tawg (kev lwj): suav nrog cov pa roj nitrogen lom.

Cov tshuaj tiv thaiv: acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, triisobutyl txhuas.

Alkali Muaj Zog: Ua rau muaj kev sib cuag nrog cov tshuaj oxidants muaj zog, ua rau muaj kev phom sij rau hluav taws thiab tawg. Ua rau muaj kev sib cuag nrog cov tshuaj nitrogen thiab cov hydrocarbons chlorinated. Ua rau muaj kua qaub. Tsis sib haum nrog cov tshuaj amino, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, alcohols, ethylene glycol, phenols, cresols, thiab caprolactam solutions. Ua rau muaj nitrocellulose. Nws kuj tsis sib haum nrog acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, thiab triisobutyl aluminum. Ua rau tooj liab, tooj liab alloys, cobalt thiab nickel xeb.

Siv
1. Siv ua tus neeg sawv cev kho kub hauv chav 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, roj purifiers, thiab lwm yam.;

4. Siv ua tus neeg sawv cev hlau chelating, cyanide-free electroplating diffusing agent, roj hmab pabcuam, brightening agent, detergent, dispersing agent, thiab lwm yam.;

5. Siv ua tus neeg sawv cev complexing, tus neeg sawv cev dehydrating rau alkaline roj, tus neeg sawv cev tiav ntaub thiab cov khoom siv hluavtaws rau ion exchanger resin thiab polyamide resin;

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

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