Kaihanga Utu Pai Dimethylbenzylamine (BDMA) CAS: 103-83-3

whakaahuatanga poto:

Ko te Dimethylbenzylamine (BDMA) he wai kore tae ki te kōwhai mārama, he kakara kakara. He iti ake te matotoru i te wai, ā, he iti noa te wairewa i roto i te wai. Ko te pāmahana mura tata ki te 140°F. Ka waikura ki te kiri, ki ngā kanohi me ngā kiriuhi mucous. He iti te paitini ina horomia, ina mimitihia, ina manawahia hoki. Whakamahia ai hei hanga i ngā piripiri me ētahi atu matū.

Ngā tono o te BDMA

He takawaenga, inā koa mō ngā pūhui ammonia quaternary; he whakakorikori tango-hauora; he aukati waikura; he whakakore waikawa; he pūhui kohua; he piripiri; he whakarerekētanga cellulose.
Ka whakamahia te N,N-Dimethylbenzylamine hei hanga i te bis[(N,N-dimethylamino)benzyl] selenide. He mea whakakorikori i roto i te tauhohenga whakamaroke o ngā hanganga o te diglycidyl ether o te bisphenol A me te tetrahydrophthalic anhydride. Ka pāngia e te ortho metallation kua tohua me te butyl lithium. Ka tauhohe ki te methyl iodide hei whiwhi i te tote ammonium, e whakamahia ana hei whakakorikori whakawhiti āhua. Hei tāpiri, ka whakamahia hei whakakorikori mō te hanganga o ngā pahuka polyurethane me ngā kapia epoxy.
I whakamahia te N,N-Dimethylbenzylamine i roto i te hanga o te bis[(N,N-dimethylamino)benzyl] selenide. Kua whakamahia hei whakakorikori i te wā e whakamaroke ana i ngā hanganga o te diglycidyl ether o te bisphenol A me te tetrahydrophthalic anhydride.

Te Whakaritenga：25% Dimethylamine Wai, 1088 karamu

Benzyl Chloride, 126.6 karamu

I roto i te taputapu o te Tauira 1, i tāpirihia te benzyl chloride i runga i te maturuturunga iho mō te wā e rua hāora ki te amine (ōwehenga molar 1 ki te 6) i te tere e ranea ana hei pupuri i te pāmahana i raro i te 40°C. I haere tonu te whakaoho i te pāmahana rūma mō tētahi atu hāora hei whakarite kia oti te tauhohenga e tohuhia ana e te whārite i raro nei.

I muri iho, i whakamataohia te ranunga tauhohenga i roto i tētahi awaawa wehewehe i a ia e tū ana i roto i tētahi pouaka whakamātao e pupurihia ana i te 5° C. ā, i wehea kia rua ngā paparanga. Ko te paparanga hinuhinu o runga, he 111.5g te taumaha, i tangohia, ā, i whakamaroketia kia kore ra ano e kitea he wāhanga hinuhinu anō i roto i te wai whakamaroketia i tōna putanga mai. I kitea kei roto i te wai whakamaroketia mata he 103.5g o te N,N-dimethylbenzylamine (76.1% o te ariā), 3.3g o te dimethylamine me te kore he tote quaternary. I whakamaroketia te dimethylamine i raro i te 29°C i raro i te pēhanga hau mai i te N,N-dimethylbenzylamine (bp 82°C/18mmHg).
