DI METHYL ETHANOLAMINE, imusanganiswa weorganic, makemikari fomura C5H13NO2, yemvura isina ruvara kana yero yakasviba ine mafuta, inogona kusanganiswa nemvura, doro, inonyungudika zvishoma mu ether. Inonyanya kushandiswa se emulsifier uye inonyudza acid gas, inodzora acid base, polyurethane foam catalyst, inoshandiswawo semishonga inodzivirira bundu senge nitrogen mustard hydrochloride intermediate.
Zvivakwa:Chigadzirwa ichi chine hwema hweammonia husina ruvara kana kuti mvura yero, inobvira moto. Chinogona kusanganiswa nemvura, ethanol, benzene, ether uye acetone. Kuwanda kwemvura 0.8879, pokufashaira 134,6℃. Pokutonhora - 59. O℃. Pokubatidza 41℃. Pokupenya (kapu yakavhurika) 40℃. Viscosity (20℃) 3.8mPa. s. Refractive index 1.4296.
Nzira yekugadzirira:
1. Maitiro eEthylene oxide ne dimethylamine ne ethylene oxide ammonia, kuburikidza nekudistilla, distillation, kupera simba remvura mumuviri.
2. Maitiro eChloroethanol anowanikwa nekushandiswa kwechloroethanol nealkali mu saponification kuti igadzire ethylene oxide, uye yozogadzirwa ne dimethylamine.
Mashandisirwo eDMEA：
Basa reN,N-dimethylethanolamine DMEA rakaderera zvikuru, uye harina simba guru pakukwira kwefuro uye kuita kwegel, asi dimethylethanolamine DMEA ine alkalinity yakasimba, iyo inogona kudzikamisa huwandu hwetrace muzvikamu zvefuro. Acids, kunyanya izvo zviri mu isocyanates, nokudaro zvinochengetedza mamwe maamines musystem. Basa rakaderera uye kugona kwakanyanya kwekudzikisa kwe dimethylethanolamine DMEA zvinoshanda sebuffer uye zvinonyanya kubatsira kana zvikashandiswa pamwe chete ne triethylenediamine, kuitira kuti reaction rate inodiwa iwanikwe ne triethylenediamine yakaderera.
Dimethylethanolamine (DMEA) ine mashandisirwo akasiyana-siyana, akadai se: dimethylethanolamine DMEA inogona kushandiswa kugadzira machira anonyungudika mumvura; dimethylethanolamine DMEA chinhu chakakosha che dimethylaminoethyl methacrylate, iyo inoshandiswa kugadzira anti-Static agents, soil conditioners, conductive materials, paper additives uye flocculants; dimethylethanolamine DMEA inoshandiswawo mukurapa mvura kudzivirira ngura yeboiler.
Mu polyurethane foam, dimethylethanolamine DMEA imhando ye co-catalyst uye reactive catalyst, uye dimethylethanolamine DMEA inogona kushandiswa mukugadzira flexible polyurethane foam uye rigid polyurethane foam. Pane hydroxyl group mumorekuru ye dimethylethanolamine DMEA, iyo inogona kuita ne isocyanate group, saka dimethylethanolamine DMEA inogona kusanganiswa ne polymer molecule, uye haizove nemhepo inoputika se triethylamine.
Kurongedza kwechigadzirwa:Uchishandisa madhiramu esimbi, huremu hwayo hunosvika 180kg padhiramu rega rega. Chengeta munzvimbo inotonhorera uye ine mhepo inofefetera. Chengeta uye takura zvichienderana nemakemikari anobvira moto uye ane chepfu.
