N,N Dimethyl aniline P touldine(CAS: 99-97-8)

dareere saliid ah oo aan midab lahayn ama huruud khafiif ah leh oo leh urta ukunta qudhmay, dhibic dhalaalaysa 130.31℃, dhibic karkaraya 211.5-212.5℃, miisaan heerkulka qolka 0.9287~0.9366g/mL, tusmada refractive 1.5360~1.5470, aan ku milmin biyaha, ku milmi dareere dabiici ah oo gaar ah, wuu burburaa marka la gaaro iftiinka.

Isticmaalka: Iyada oo ah sawir-qaade wax ku ool ah oo loogu talagalay polymerization-ka acrylonitrile (AN), waxaa si weyn loogu isticmaalaa soo saarista agabka ilkaha ee is-dejiya, agabka wax lagu dhejiyo iyo dhejisyada anaerobic-ka acrylic. Xawaaraha polymerization-ku wuxuu la mid yahay awoodda 1.62 ee fiirsashada AN iyo awoodda 0.62 ee fiirsashada DMT. Badeecadan waxaa badanaa loo isticmaalaa dardar-geliye ahaan. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa dardar-geliye bogsiiya resin polyester aan dheregsanayn waxaana loo isticmaalaa in lagu hagaajiyo marin-u-helka qolofka kaabsal. DMT waa dardar-geliye polymerization ah, sida saxaaradaha ilkaha ee loogu talagalay qalabka ilkaha lagu tallaalo. Qaybteeda ugu weyn waa methyl methacrylate, iyadoo peroxide uu yahay bilaabaha. Habka polymerization-ka caadiga ah waa in lagu adkeeyo iyadoo lagu kululeynayo biyo karkaraya 100°C muddo 40 daqiiqo ah. . Haddii 0.8% amines-ka saddexaad lagu daro, sida N,N-dimethyl-p-toluidine iyo N,N-diisopropanol-p-toluidine, qaabaynta ayaa iskeed u bogsan karta dhowr daqiiqo gudahood heerkulka qolka. Tani waxay sabab u tahay xaqiiqda ah in amiinada saddexaad ee Amine catalysis ay dardargeliso kala-goynta peroxide heerkulka qolka, taasoo dardar gelinaysa habka polymerization-ka ee methyl methacrylate. Marka laga soo tago agabka ilkaha, polymerization-ka plexiglass ee shisheeye wuxuu sidoo kale adeegsadaa habka is-isku-ururinta catalytic. Ku darista 0.8% DMT inta lagu jiro polymerization waxay kor u qaadaysaa polymerization-ka iyo isku-xidhka iskutallaabta. Tani waxay badbaadin kartaa shaqada iyo waqtiga, waxayna si weyn u horumarin kartaa tayada asalka ah. Awoodda wax soo saarka qalabka.
