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

he wai hinuhinu kore tae, he kowhai marama ranei me te haunga o nga hua pirau, ira whakarewa 130.31 ℃, ira koropupū 211.5-212.5 ℃, te taumaha i te pāmahana rūma 0.9287~0.9366g/mL, taupū refractive 1.5360~1.5470, korere i roto i etahi wai. Ko te whakarewa pararopi, ka pirau ina kitea ki te marama.

Te Whakamahinga: Hei kaiwhakaahua whakaahua whai hua mo te polymerization acrylonitrile (AN), ka whakamahia nuitia i roto i te hanga o nga rauemi niho tere-whaiaro, nga mea hangai me nga taapiri anaerobic kiriaku. Ko te tere polymerization he rite ki te kaha 1.62 o te kaha o te AN me te kaha 0.62 o te DMT. Ka whakamahia tenei hua hei whakatere. I tua atu, ka taea hoki te whakamahi hei whakatere whakaora mo te kapia polyester haunga ka whakamahia hei whakapai ake i te uruhanga o nga anga capsule. Ko te DMT he whakatere polymerization, penei i nga paepae niho mo nga whakaurunga niho. Ko tana waahanga matua ko te methyl methacrylate, me te peroxide hei kaikawe. Ko te tukanga polymerization o mua ko te whakamaroke ma te whakamahana i roto i te wai kohua i te 100°C mo te 40 meneti. . Mena ka taapirihia te 0.8% o nga amine tuatoru, penei i te N,N-dimethyl-p-toluidine me te N,N-diisopropanol-p-toluidine, ka taea te rongoa i roto i nga meneti torutoru i te pāmahana rūma. Ko tenei na te mea ko nga amine tuatoru Amine catalysis ka whakatere i te pirau o te peroxide i te pāmahana rūma, na reira ka whakatere i te tukanga polymerization o te methyl methacrylate. I tua atu i nga taonga niho, ka whakamahia ano hoki e te polymerization plexiglass o kee he tukanga whakawera-whaiaro catalytic. Ko te taapiri i te 0.8% DMT i te wa o te polymerization ka whakatairanga i te polymerization me te hononga-whakawhiti. Ma tenei ka whakaora i te mahi me te wa, ka taea te whakapai ake i te kounga taketake. Te kaha whakaputa taputapu.
