Mea Hana Maikaʻi Kumukuai Dimethylbenzylamine (BDMA) CAS:103-83-3

wehewehe pōkole:

ʻO ka Dimethylbenzylamine (BDMA) he wai melemele ʻole me ka ʻala ʻala. ʻOi iki ka mānoanoa ma mua o ka wai a hiki ke hoʻoheheʻe ʻia i ka wai. Ke kuhi uila ma kahi o 140°F. He mea ʻino i ka ʻili, nā maka a me nā ʻāʻī. He mea ʻawaʻawa iki ma ka ʻai ʻana, ka ʻili a me ka inhalation. Hoʻohana ʻia i ka hana ʻana i nā adhesives a me nā mea ʻē aʻe.

Kūwaena, ʻoi loa no nā pūhui ammonium quaternary; dehydrohalogenating catalyst; mea hoʻokuʻi ʻino; ʻakika neutralizer; nā pūhui potting; nā mea hoʻopili; mea hoʻololi cellulose.
Hoʻohana ʻia ʻo N,N-Dimethylbenzylamine i ka hoʻomākaukau ʻana i ka bis[(N,N-dimethylamino)benzyl] selenide. Hana ia ma ke ʻano he mea hoʻoikaika i ka hoʻōla ʻana o nā ʻano o ka diglycidyl ether o ka bisphenol A a me ka tetrahydrophthalic anhydride. Hoʻokomo ʻia ka metalation ortho me ka lithium butyl. Hoʻopili ia me ka methyl iodide e kiʻi i ka paʻakai ammonium, kahi i hoʻohana ʻia e like me nā catalysts hoʻololi. Eia kekahi, hoʻohana ʻia ia ma ke ʻano he catalyst no ka hoʻokumu ʻana o ka polyurethane foams a me nā resins epoxy.
Ua hoʻohana ʻia ʻo N,N-Dimethylbenzylamine i ka synthesis o bis[(N,N-dimethylamino)benzyl] selenide. Ua hoʻohana ʻia ʻo ia ma ke ʻano he catalyst i ka wā e hoʻōla ai i ka hopena o nā ʻano o ka diglycidyl ether o bisphenol A a me ka tetrahydrophthalic anhydride.

I loko o ka mea hana o ka La'ana 1, ua ho'okomo 'ia ka benzyl chloride i ka kulu ma luna o ka manawa 'elua hola i ka amine ( ratio molar 1 a hiki i ka 6) ma ka laiki i lawa no ka mālama 'ana i ka mahana ma lalo o 40°C. Hoʻomau ʻia ka hoʻoulu ʻana ma ka lumi wela no hoʻokahi hola hou e hōʻoia i ka pau ʻana o ka pane i hōʻike ʻia e ka hoohalike ma lalo nei.

Ma hope iho, ua hoʻomāʻalili ʻia ka hui ʻana i loko o kahi funnel kaʻawale ʻoiai e kū ana i loko o ka friji i mālama ʻia ma 5 ° C. a hoʻokaʻawale ʻia i ʻelua papa. ʻO ka papa aila luna, he 111.5g kona kaumaha, ua wehe ʻia a hoʻoheheʻe ʻia ka mahu a hiki i ka ʻike ʻole ʻia ʻana o kekahi mea oleaginous hou i loko o ka distillate i kona hele ʻana mai. Ua ʻike ʻia ka distillate crude he 103.5g o N,N-dimethylbenzylamine (76.1% o ka manaʻo), 3.3g o dimethylamine a ʻaʻohe paʻakai quaternary. Ua hoʻoheheʻe ʻia ka dimethylamine ma lalo o 29°C ma lalo o ke kaomi ea mai ka N,N-dimethylbenzylamine (bp 82°C/18mmHg).
