Iyini i-N,N-Dimethyloctadecylamine Nge-CAS 124-28-7?

Uketshezi lwe-viscous onsundu ngokukhanyayo, utshani olukhanyayo oluphuzi oluqinile oluqinile ku-20℃. Incibilika kuzincibilikisi zotshwala, ezingancibiliki emanzini. Nge-octadecylamine, i-formaldehyde, i-formic acid etholwe ngokujiya. Okokuqala engeza i-octadecylamine ku-reactor, ugovuze ngokulinganayo endaweni ye-ethanol, ulawule izinga lokushisa ku-50-60 °C, engeza i-formic acid, ugovuze imizuzu embalwa, engeza i-formaldehyde ku-60-65 °C, ukushisa kufika ku-80-83 °C, reflux amahora ama-2 , nciphisa nge-liquid caustic soda ukuze wenze inani le-pH libe likhulu kuno-10, umele i-stratification, khipha amanzi, khipha i-ethanol nge-vacuum distillation, bese upholisa ukuze uthole i-N,N-dimethyloctadecylamine.

Isicelo

Lo mkhiqizo uyi-organic synthesis ebalulekile ephakathi kwe-quaternary ammonium salt type cationic surfactant. Ingasabela nge-ethylene oxide, i-dimethyl sulfate, i-diethyl sulfate, i-methyl chloride, i-benzyl chloride, njll. Ingasetshenziswa futhi ukukhiqiza izinto ezixosha izinambuzane. I-N,N-Dimethyloctadecylamine ihlangana ne-ethylene oxide ne-nitric acid ukuze ithole i-octadecyldimethylhydroxyethyl quaternary ammonium nitrate, okuyi-ejenti elwa nokuvuvukala.
