N,N-Dimethyl-p-toluidine CAS：99-97-8

Katundu wa N,N-Dimethyl-p-toluidine, ntchito ndi njira zopangira

N,N-dimethyl-p-toluidine ndi madzi amafuta opanda mtundu kapena achikasu owala okhala ndi fungo la dzira lovunda, losungunuka 130.31℃, kutentha 211.5-212.5℃, kulemera 0.9287-0.9366g/mL kutentha kwa chipinda, refractive index 1.5360-1.5470, yosasungunuka m'madzi, yosungunuka m'madzi enae organic solvents, yomwe imawola ndi kuwala. Imagwiritsidwa ntchito ngati photoinitiator yothandiza pa polymerization ya acrylonitrile (AN), ndipo liwiro lake la polymerization limagwirizana ndi 1.62nd ya AN concentration ndi 0.62nd ya DMT concentration. Chogulitsachi chimagwiritsidwa ntchito kwambiri ngati accelerator komanso, kuwonjezera apo, ngati chowonjezera pakupanga ma polyester osakhuta komanso mu ma bonding agents. Njira yopangira: N,N-dimethyl-p-toluidine imapangidwa pogwiritsa ntchito dimethyl sulfate ngati methylating agent pa kutentha kochepa komanso kuthamanga kwa mpweya. N,4-dimethyl-N-(3-phenylprop-2-ynyl)benzylmine ndi N-(methyl(p-tolyl)amino)methyl)benzamide zimatha kupangidwa ndi iron-catalyzed oxidative CC coupling ndi phenacetylene ndi benzamide pamaso pa di-tert-butyl peroxide, motsatana.
