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

whakaahuatanga poto:

Ko te Dimethylbenzylamine (BDMA) he wai kore tae ki te kowhai marama me te kakara kakara. He iti ake te mātotoru i te wai me te memeha noa ki te wai. Ira hiko tata ki te 140°F. He kino ki te kiri, ki nga kanohi me nga kiri mucous. He paitini iti na te horomia, te tango kiri me te whakangohanga. Ka whakamahia i roto i te hanga whakapiri me etahi atu matū.

Nga tono mo te BDMA

Takawaenga, ina koa mo nga puhui haukinia quaternary; whakakōkī dehydrohalogenating; te aukati waikura; te whakakore waikawa; pūhui kohua; whakapiringa; whakakē cellulose.
Ka whakamahia te N,N-Dimethylbenzylamine ki te whakarite i te bis[(N,N-dimethylamino)benzyl] selenide. Ka mahi hei whakakorikori i te tauhohenga whakaora o nga hanganga o te diglycidyl ether o te bisphenol A me te tetrahydrophthalic anhydride. Ka tukuna te whakarewatanga ortho me te lithium butyl. Ka tauhohe ki te methyl iodide ki te tiki i te tote haukinia, ka whakamahia hei whakakōkī whakawhiti wāhanga. I tua atu, ka whakamahia hei whakakorikori mo te hanga o te pahuka polyurethane me te kapia epoxy.
I whakamahia te N,N-Dimethylbenzylamine ki te whakahiato o te bis[(N,N-dimethylamino)benzyl] selenide. I whakamahia hei whakakorikori i te tauhohenga whakaora o nga waihanga o te diglycidyl ether o te bisphenol A me te tetrahydrophthalic anhydride.

Te Whakaritenga: 25% Aqueous Dimethylamine, 1088 karamu

Benzyl Chloride, 126.6 karamu

I roto i te taputapu o te Tauira 1, ka taapirihia te benzyl chloride i roto i te rua haora ki te amine (molar ōwehenga 1 ki te 6) i te tere e tika ana kia mau tonu te mahana i raro i te 40°C. I haere tonu te whakakorikori i te pāmahana rūma mo tetahi atu haora hei whakarite i te otinga o te tauhohenga e tohuhia ana e te whārite i raro nei.

I muri mai ka whakamataohia te ranunga tauhohenga i roto i te kohanga wehe i te wa e tu ana i roto i te pouaka whakamahana i mau ki te 5° C. ka wehea kia rua nga paparanga. Ko te paparanga hinu o runga, 111.5g te taumaha, ka tangohia, ka whakamarohia te mamaoa kia kore ra ano tetahi atu waahanga hinu i kitea i roto i te distillate i te taenga mai. I kitea te 103.5g o te N,N-dimethylbenzylamine (76.1% o te ariā), te 3.3g o te dimethylamine me te kore o te tote quaternary. I whakakorehia te dimethylamine i raro i te 29°C i raro i te pehanga hau mai i te N,N-dimethylbenzylamine (bp 82°C/18mmHg).
