DI METHYL ETHANOLAMINE (DMEA)

DI METHYL ETHANOLAMINE, jẹ ẹya ara ẹrọ Organic, agbekalẹ kemikali C5H13NO2, fun awọ ti ko ni awọ tabi omi ororo ofeefee dudu, le jẹ miscible pẹlu omi, oti, tiotuka diẹ ninu ether.Ti a lo ni akọkọ bi emulsifier ati famu gaasi acid, aṣoju iṣakoso ipilẹ acid, ayase foam polyurethane, tun lo bi awọn oogun antitumor bii nitrogen mustard hydrochloride agbedemeji.

DI METHYL ETHANOLAMINE1Awọn ohun-ini:Ọja yii ni olfato amonia ti ko ni awọ tabi omi alawọ ofeefee, flammable.O le jẹ miscible pẹlu omi, ethanol, benzene, ether ati acetone.Ojulumo iwuwo 0.8879, farabale ojuami 134,6 ℃.Aaye didi - 59. O℃.Aaye ina 41 ℃.Filasi ojuami (ìmọ ago) 40 ℃.iki (20℃) 3.8mPa.s.Atọka itọka 1.4296.

Ọna igbaradi:

1.Ethylene oxide ilana nipasẹ dimethylamine ati ethylene oxide amonia, nipasẹ distillation, distillation, gbígbẹ.

2.Chloroethanol ilana ti wa ni gba nipasẹ awọn saponification ti chloroethanol ati alkali lati gbe awọn ethylene oxide, ati ki o si sise pẹlu dimethylamine.

 Awọn ohun elo ti DMEA:

Iṣẹ ṣiṣe catalytic ti N, N-dimethylethanolamine DMEA ti lọ silẹ pupọ, ati pe o ni ipa diẹ lori dide foomu ati ifasẹ gel, ṣugbọn dimethylethanolamine DMEA ni alkalinity ti o lagbara, eyiti o le ṣe imunadoko iye itọpa ninu awọn paati foaming Acids, ni pataki awọn ti o wa ni isocyanates. , nitorina ni idaduro awọn amines miiran ninu eto naa.Iṣẹ kekere ati agbara didoju giga ti dimethylethanolamine DMEA ṣe bi ifipamọ ati pe o jẹ anfani ni pataki nigba lilo ni apapo pẹlu triethylenediamine, ki oṣuwọn ifasẹyin ti o fẹ le ṣee ṣe pẹlu awọn ifọkansi kekere ti triethylenediamine.

Dimethylethanolamine (DMEA) ni ọpọlọpọ awọn lilo, gẹgẹbi: dimethylethanolamine DMEA le ṣee lo lati ṣeto awọn ohun elo ti omi-dilutable;dimethylethanolamine DMEA tun jẹ ohun elo aise fun dimethylaminoethyl methacrylate, eyiti a lo lati ṣeto awọn aṣoju anti-Static, awọn amúṣantóbi ilẹ, awọn ohun elo imudani, awọn afikun iwe ati awọn flocculants;dimethylethanolamine DMEA tun lo ninu awọn aṣoju itọju omi lati ṣe idiwọ ipata igbomikana.

Ninu foam polyurethane, dimethylethanolamine DMEA jẹ oludasiṣẹ-apapọ ati oludasiṣẹ ifaseyin, ati dimethylethanolamine DMEA le ṣee lo ni iṣelọpọ ti foam polyurethane rọ ati foam polyurethane lile.Ẹgbẹ hydroxyl kan wa ninu moleku ti dimethylethanolamine DMEA, eyiti o le fesi pẹlu ẹgbẹ isocyanate, nitorinaa dimethylethanolamine DMEA le ni idapo pẹlu molecule polymer, ati pe kii yoo jẹ iyipada bi triethylamine.

Iṣakojọpọ ọja:Lilo idii ilu irin, iwuwo apapọ 180kg fun ilu kan.Tọju ni itura kan ati ki o ventilated ibi.Tọju ati gbigbe ni ibamu si awọn kemikali ina ati majele.
