Di methyl ethanolamine, yog cov organic sib xyaw, rau cov mis nyuj C5H13no Mas siv cov roj thiab kua qaub cov roj av tshuaj, polyurethane ua npuas ncauj categalt, kuj siv los ua nitrogen mustard mustard mydermoriate.
Khoom:Cov khoom no muaj ammonia tsw ntxhiab tsw lossis kua daj, ua kua taus. Nws tuaj yeem ua kom tiav nrog dej, ethanol, benzene, ete thiab acetone. Txheeb ze ceev 0.8879, boiling point 134,6 ℃. Kov taw tes khov - 59. O ℃. Ignition point 41 ℃. Flash taw tes (qhib khob) 40 ℃. Viscosity (20 ℃) 3.8Mpa. s. Refacking Index 1.4296.
Kev npaj txoj kev:
1.ethylene oxide cov txheej txheem los ntawm Dimethylamine thiab Ethylene OXIDE Ammonia, los ntawm distillation, distillation, lub cev qhuav dej, lub cev qhuav dej.
2.Chloroethanol txheej txheem yog tau los ntawm saponification ntawm chloroethanol thiab alkali los tsim ethylene oxide, thiab tom qab ntawd synthesized nrog detethylamine.
Cov ntawv thov ntawm DMEA:
Cov kev ua si catalytic ntawm n, n-dimethylethangine DMEA muaj peev xwm tsawg heev, thiab nws muaj cov txiaj ntsig me me, tab sis tsis muaj txiaj ntsig rau hauv cov txheej txheem ua npuas dej acids, tshwj xeeb tshaj yog cov hauv Isocyanates , yog li khaws cia lwm cov amines hauv lub system. Qhov kev ua ub no tsawg thiab muaj peev xwm nruab nrab muaj peev xwm ntawm Doshleytisanoline D TheEs thiab yog tias cov tshuaj tiv thaiv zoo tshaj plaws uas tau ua tiav nrog cov tshuaj tiv thaiv qis ntawm trietylenediamine.
Dimethylethangine (DMEA) muaj ntau yam ntawm kev siv, xws li: Dretylethangethanbon DMEA tuaj yeem siv los npaj cov dej dej ntws; dimethylethatanolamine DMea kuj yog cov khoom siv raw rau cov neeg sawv cev ua kom muaj zog, cov khoom siv tsis zoo, cov ntaub ntawv sau, cov ntawv sau thiab flocculants; Dosethylethangamine D sawv ntxov kuj yog siv rau cov neeg sawv cev dej kom tiv thaiv kev xeb boiler.
Hauv polyurethane ua npuas dej, dimethylethanbon dmehlalthans thiab reathylethans thiab dimtive catulationanolamam ua npuas thiab siv zog polyurethane ua npuas ncauj. Muaj cov pab pawg hydroxyl hauv cov molecule ntawm Dostylethatanoline D sawv daws, thiab nws yuav ua ke nrog lub zog polymer, thiab nws yuav tsis yog volatile li triethylamine.
Cov Khoom Ntim:Siv Hlau Nruas Ntim, Net Nyhav 180Kg Rau Ib Nruas. Khaws rau hauv qhov chaw txias thiab muaj qhov cua. Khaws thiab thauj raws li cov nplaim hluav taws thiab cov tshuaj lom.
