Mtengo Wabwino Wopanga Dimethylbenzylamine (BDMA) CAS:103-83-3

kufotokozera mwachidule:

Dimethylbenzylamine (BDMA) ndi madzi opanda mtundu kapena achikasu owala okhala ndi fungo lonunkhira bwino. Osakhuthala pang'ono kuposa madzi ndipo amasungunuka pang'ono m'madzi. Flash point pafupifupi 140°F. Amawononga khungu, maso ndi nembanemba ya mucous. Ndi poizoni pang'ono akameza, kuyamwa khungu ndi kupuma. Amagwiritsidwa ntchito popanga zomatira ndi mankhwala ena.

Kugwiritsa ntchito BDMA

Yapakatikati, makamaka ya mankhwala a ammonium a quaternary; chothandizira kuchotsa ma hydrohalogenating; choletsa dzimbiri; choletsa asidi; mankhwala ophera m'miphika; zomatira; chosinthira cellulose.
N,N-Dimethylbenzylmine imagwiritsidwa ntchito popanga bis[(N,N-dimethylamino)benzyl] selenide. Imagwira ntchito ngati chothandizira pakuchiritsa kwa mapangidwe a diglycidyl ether a bisphenol A ndi tetrahydrophthalic anhydride. Imadutsa mu ortho metalation yolunjika ndi butyl lithium. Imayanjana ndi methyl iodide kuti ipange mchere wa ammonium, womwe umagwiritsidwa ntchito ngati zoyambitsa kusintha kwa gawo. Kuphatikiza apo, imagwiritsidwa ntchito ngati chothandizira popanga ma polyurethane foams ndi epoxy resins.
N,N-Dimethylbenzylmine idagwiritsidwa ntchito popanga bis[(N,N-dimethylamino)benzyl] selenide. Yagwiritsidwa ntchito ngati chothandizira pakuchiritsa kwa mapangidwe a diglycidyl ether a bisphenol A ndi tetrahydrophthalic anhydride.

Kukonzekera: 25% Dimethylamine yamadzi, 1088 magalamu

Benzyl Chloride, magalamu 126.6

Mu chipangizo cha Chitsanzo 1, benzyl chloride inawonjezedwa pang'onopang'ono kwa maola awiri ku amine (chiŵerengero cha molar 1 mpaka 6) pa liwiro lokwanira kusunga kutentha pansi pa 40°C. Kusakaniza kunapitilizidwa kutentha kwa chipinda kwa ola limodzi kuti kutsimikizire kuti kukwaniritsidwa kwa zomwe zafotokozedwa ndi equation pansipa kwatha.

Pambuyo pake, chisakanizocho chinazizidwa mu funnel yolekanitsa pamene chinali mufiriji yosungidwa pa 5°C. ndipo chinalekanitsidwa m'magawo awiri. Gawo lapamwamba la mafuta, lolemera 111.5g, linachotsedwa ndipo linasungunuka ndi nthunzi mpaka palibe gawo lina la oleaginous lomwe linapezeka mu distillate pamene linatuluka. Distillate yopanda mafuta inapezeka kuti ili ndi 103.5g ya N,N-dimethylbenzylamine (76.1% ya chiphunzitso), 3.3g ya dimethylamine ndipo palibe mchere wa quaternary. Dimethylamine inasungunuka pansi pa 29°C pansi pa mphamvu ya mlengalenga kuchokera ku N,N-dimethylbenzylamine (bp 82°C/18mmHg).
