N,N-Dimethyloctadecylamine Me CAS 124-28-7 No nā Surfactants
Wai ʻeleʻele māmā, melemele mauʻu palupalu paʻa ma 20 ℃. Hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe waiʻona, ʻaʻole hoʻoheheʻe ʻia i ka wai. Ma octadecylamine, formaldehyde, formic acid i loaʻa ma o ka condensation. E hoʻohui mua i ka octadecylamine i loko o ka reactor, e hoʻoulu like i loko o ka medium ethanol, e kāohi i ka mahana ma 50-60 °C, e hoʻohui i ka formic acid, e hoʻoulu no kekahi mau minuke, e hoʻohui i ka formaldehyde ma 60-65 °C, e hoʻomehana a hiki i 80-83 °C, reflux no 2 mau hola, e hoʻopau me ka soda caustic wai e hoʻonui i ka waiwai pH ma mua o 10, e kū no ka stratification, e wehe i ka wai, e wehe i ka ethanol ma o ka distillation vacuum, a laila e hoʻomaʻalili e loaʻa ai ka N,N-dimethyloctadecylamine.

He mea nui kēia huahana i ka synthesis organik waena o ka quaternary ammonium salt type cationic surfactant. Hiki iā ia ke hana me ka ethylene oxide, dimethyl sulfate, diethyl sulfate, methyl chloride, benzyl chloride, a me nā mea ʻē aʻe e hana i nā cation paʻakai ammonium quaternary like ʻole, hiki ke hoʻohana ʻia no ka palupalu ʻana i ka lole, ka mea antistatic, ka hoʻomaikaʻi ʻana i ka hiki ke kāwili i ka lauoho a me nā huahana ʻē aʻe. Hiki ke hoʻohana ʻia e hana i nā mea pale pepeke. Hana ʻo N,N-Dimethyloctadecylamine me ka ethylene oxide a me ka nitric acid e loaʻa ai ka octadecyldimethylhydroxyethyl quaternary ammonium nitrate, he mea antistatic.
