N, N-Dimethyloctadecylamine Nrog CAS 124-28-7 Rau Surfactants
Lub teeb xim av viscous kua, lub teeb straw daj muag khoom ntawm 20 ℃. Soluble nyob rau hauv cawv solvents, insoluble nyob rau hauv dej. Los ntawm octadecylamine, formaldehyde, formic acid tau los ntawm condensation. Ua ntej ntxiv octadecylamine rau hauv lub reactor, do sib npaug hauv ethanol nruab nrab, tswj qhov kub ntawm 50-60 ° C, ntxiv formic acid, do rau ob peb feeb, ntxiv formaldehyde ntawm 60-65 ° C, kub txog 80-83 ° C, reflux rau 2 teev, neutralize nrog kua caustic soda kom pH tus nqi siab tshaj 10, sawv ntsug rau stratification, tshem tawm dej, tshem tawm ethanol los ntawm lub tshuab nqus tsev distillation, thiab ces txias kom tau N, N-dimethyloctadecylamine.

Cov khoom no yog ib qho tseem ceeb organic synthesis nruab nrab ntawm quaternary ammonium ntsev hom cationic surfactant. Nws tuaj yeem cuam tshuam nrog ethylene oxide, dimethyl sulfate, diethyl sulfate, methyl chloride, benzyl chloride, thiab lwm yam los tsim cov quaternary ammonium ntsev cations sib txawv, uas tuaj yeem siv rau cov ntaub softening, antistatic tus neeg saib xyuas, txhim kho cov plaub hau combability thiab lwm yam khoom. Nws kuj tseem siv tau los tsim cov tshuaj tua kab. N, N-Dimethyloctadecylamine reacts nrog ethylene oxide thiab nitric acid kom tau octadecyldimethylhydroxyethyl quaternary ammonium nitrate, uas yog ib tug antistatic tus neeg sawv cev.
