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

dareere saliid ah oo huruud ah oo aan midab lahayn ama khafiif ah oo leh urta ukunta qudhuntay, barta dhalaalaysa 130.31 ℃, barta karkarinta 211.5-212.5 ℃, miisaanka heerkulka qolka 0.9287 ~ 0.9366g/mL, index refractive 1.5360 ~ 1.5470, biyo aan milmi karin Walxaha dabiiciga ah, wuu burburaa marka iftiinku soo baxo.

Isticmaalka: Sida sawir-qaade wax ku ool ah oo loogu talagalay acrylonitrile (AN) polymerization, waxaa si ballaaran loo isticmaalaa soo saarista qalabka ilkaha ee is-dejinta degdega ah, qalabka wax lagu dhejiyo iyo xabagta anaerobic acrylic. Xawaaraha polymerization wuxuu u dhigmaa awoodda 1.62 ee xoojinta AN iyo awoodda 0.62 ee diiradda DMT. Alaabtan waxaa badanaa loo isticmaalaa dardar-geliyaha. Intaa waxaa dheer, waxa kale oo loo isticmaali karaa sida dardar-daawaynta loogu talagalay xabagta polyester-ka aan saturated oo loo isticmaalo si loo hagaajiyo permeability ee qolof kaabsoosha. DMT waa dardar-geliyaha polymerization, sida saxamada ilkaha ee beer-qaadaha. Qaybteeda ugu muhiimsan waa methyl methacrylate, oo leh peroxide sida bilawga. Habka polymerization ee caadiga ah waa in lagu adkeeyo kuleylinta biyaha karkaraya 100 ° C 40 daqiiqo. . Haddii 0.8% amines sare lagu daro, sida N,N-dimethyl-p-toluidine iyo N,N-diisopropanol-p-toluidine, wax-soo-saarka waxaa lagu daweyn karaa lafteeda dhowr daqiiqo gudahood heerkulka qolka. Tani waxay sabab u tahay xaqiiqda ah in amines jaamacadeed Amine catalysis ay dedejiso kala-goynta peroxide heerkulka qolka, taas oo dardargelinaysa habka polymerization ee methyl methacrylate. Waxa intaa dheer in qalabka ilkaha, polymerization plexiglass shisheeye sidoo kale waxay isticmaashaa habka is-condensation katalytic. Ku darista 0.8% DMT inta lagu jiro polymerization waxay kor u qaadaysaa polymerization iyo isku-xidhka labadaba. Tani waxay badbaadisaa shaqada iyo waqtiga, waxayna si weyn u hagaajin kartaa tayada asalka ah. Awoodda wax soo saarka qalabka.
