wehewehe pōkole:

He wai melemele ʻole a māmā paha ka Dimethylbenzylamine (BDMA) me kahi ʻala ʻala. ʻOi aku ka liʻiliʻi o ka mānoanoa ma mua o ka wai a hoʻoheheʻe iki ʻia i ka wai. ʻO ka lapalapa ma kahi o 140°F. ʻAi ʻino i ka ʻili, nā maka a me nā membrane mucous. ʻAi iki ka ʻawahia ma ka ʻai ʻana, ka omo ʻana o ka ʻili a me ka hanu ʻana. Hoʻohana ʻia i ka hana ʻana i nā mea hoʻopili a me nā kemika ʻē aʻe.

Waena, ʻoi aku hoʻi no nā hui ammonium quaternary; mea hoʻoulu dehydrohalogenating; mea hoʻopau i ka palaho; mea hoʻopau waikawa; nā hui potting; nā mea hoʻopili; mea hoʻololi cellulose.
Hoʻohana ʻia ʻo N,N-Dimethylbenzylamine i ka hoʻomākaukau ʻana o bis[(N,N-dimethylamino)benzyl] selenide. Hana ia ma ke ʻano he mea hoʻoulu i ka hopena hoʻōla o nā ʻano hana o diglycidyl ether o bisphenol A a me tetrahydrophthalic anhydride. Ke hele nei ia i ka ortho metalation i kuhikuhi ʻia me ka butyl lithium. Hana ia me ka methyl iodide e loaʻa ai ka paʻakai ammonium, kahi i hoʻohana ʻia ma ke ʻano he mau mea hoʻoulu hoʻoili pae. Eia kekahi, hoʻohana ʻia ia ma ke ʻano he mea hoʻoulu no ka hoʻokumu ʻana o nā foams polyurethane a me nā resins epoxy.
Ua hoʻohana ʻia ʻo N,N-Dimethylbenzylamine i ka hana ʻana o bis[(N,N-dimethylamino)benzyl] selenide. Ua hoʻohana ʻia ia ma ke ʻano he mea hoʻoulu i ka wā o ka hoʻōla ʻana i nā ʻano hana o ka diglycidyl ether o bisphenol A a me ka tetrahydrophthalic anhydride.

Hoʻomākaukau ʻana：25% Aqueous Dimethylamine, 1088 grams

Benzyl Chloride, 126.6 grams

I loko o ka mea hana o ka Laʻana 1, ua hoʻohui ʻia ka benzyl chloride i kulu iho ma luna o ʻelua hola i ka amine (molar ratio 1 a 6) ma kahi wikiwiki e lawa ai e mālama i ka mahana ma lalo o 40°C. Ua hoʻomau ʻia ka hoʻoulu ʻana ma ka mahana o ka lumi no hoʻokahi hola hou e hōʻoia i ka pau ʻana o ka hopena i hōʻike ʻia e ka hoohalike ma lalo nei.

Ma hope iho, ua hoʻomaʻalili ʻia ka hui ʻana o ka hopena i loko o kahi funnel hoʻokaʻawale ʻoiai e kū ana i loko o kahi pahu hau i mālama ʻia ma 5° C. a ua hoʻokaʻawale ʻia i ʻelua papa. ʻO ka papa ʻaila o luna, he 111.5g ke kaumaha, ua wehe ʻia a ua hoʻoheheʻe ʻia i ka mahu a hiki i ka ʻike ʻole ʻia ʻana o kahi ʻāpana oleaginous hou aʻe i loko o ka distillate i kona puka ʻana mai. Ua ʻike ʻia aia i loko o ka distillate maka he 103.5g o N,N-dimethylbenzylamine (76.1% o ke kumumanaʻo), 3.3g o dimethylamine a ʻaʻohe paʻakai quaternary. Ua hoʻoheheʻe ʻia ka dimethylamine ma lalo o 29°C ma lalo o ke kaomi lewa mai ka N,N-dimethylbenzylamine (bp 82°C/18mmHg).
