DI METHYL ETHANOLAMINE (DMEA)

DI METHYL ETHANOLAMINE, yog ib qho organic compound, tshuaj mis C5H13NO2, rau cov kua roj tsis muaj xim lossis tsaus daj, tuaj yeem sib xyaw nrog dej, cawv, me ntsis soluble hauv ether. Feem ntau siv ua emulsifier thiab acid roj absorbent, acid base control agent, polyurethane ua npuas ncauj catalyst, kuj siv ua tshuaj antitumor xws li nitrogen mustard hydrochloride intermediate.

DI METHYL ETHANOLAMINE 1Cov Khoom:Cov khoom no muaj ntxhiab ammonia tsis muaj xim lossis kua daj, yooj yim hlawv. Nws tuaj yeem sib xyaw nrog dej, ethanol, benzene, ether thiab acetone. Qhov ceev sib piv 0.8879, boiling point 134,6 ℃. Freezing point - 59. O ℃. Ignition point 41 ℃. Flash point (qhib khob) 40 ℃. Viscosity (20 ℃) ​​3.8mPa. s. Refractive index 1.4296.

Txoj kev npaj:

1. Cov txheej txheem ethylene oxide los ntawm dimethylamine thiab ethylene oxide ammonia, los ntawm kev distillation, distillation, dehydration.

2. Cov txheej txheem Chloroethanol yog tau los ntawm kev saponification ntawm chloroethanol thiab alkali los tsim ethylene oxide, thiab tom qab ntawd synthesized nrog dimethylamine.

 Cov ntawv thov ntawm DMEA

Qhov kev ua haujlwm catalytic ntawm N,N-dimethylethanolamine DMEA yog qis heev, thiab nws muaj me ntsis cuam tshuam rau kev nce ntawm cov ua npuas ncauj thiab cov tshuaj tiv thaiv gel, tab sis dimethylethanolamine DMEA muaj zog alkalinity, uas tuaj yeem ua kom cov kua qaub tsis muaj zog hauv cov khoom ua npuas ncauj, tshwj xeeb tshaj yog cov hauv isocyanates, yog li khaws lwm cov amines hauv lub cev. Qhov kev ua haujlwm qis thiab muaj peev xwm ua kom tsis muaj zog ntawm dimethylethanolamine DMEA ua haujlwm ua lub buffer thiab tshwj xeeb tshaj yog thaum siv ua ke nrog triethylenediamine, yog li qhov nrawm xav tau tuaj yeem ua tiav nrog cov concentration qis ntawm triethylenediamine.

Dimethylethanolamine (DMEA) muaj ntau yam kev siv, xws li: dimethylethanolamine DMEA tuaj yeem siv los npaj cov txheej txheem dej-dilutable; dimethylethanolamine DMEA kuj tseem yog cov khoom siv raw rau dimethylaminoethyl methacrylate, uas yog siv los npaj cov neeg sawv cev tiv thaiv Static, av conditioners, conductive cov ntaub ntawv, cov ntawv ntxiv thiab flocculants; dimethylethanolamine DMEA kuj tseem siv rau hauv cov neeg sawv cev kho dej kom tiv thaiv kev xeb boiler.

Hauv polyurethane ua npuas ncauj, dimethylethanolamine DMEA yog ib qho co-catalyst thiab ib qho reactive catalyst, thiab dimethylethanolamine DMEA tuaj yeem siv rau hauv kev tsim cov polyurethane ua npuas ncauj thiab polyurethane ua npuas ncauj. Muaj ib pawg hydroxyl hauv lub molecule ntawm dimethylethanolamine DMEA, uas tuaj yeem cuam tshuam nrog isocyanate pawg, yog li dimethylethanolamine DMEA tuaj yeem ua ke nrog lub molecule polymer, thiab nws yuav tsis volatile zoo li triethylamine.

Cov khoom ntim:Siv lub thawv ntim hlau, qhov hnyav tag nrho yog 180kg rau ib lub nruas. Khaws cia rau qhov chaw txias thiab muaj cua nkag. Khaws cia thiab thauj mus rau qhov chaw uas muaj cov tshuaj lom thiab cov tshuaj uas yooj yim hlawv.
