N, N-Dimethyloctadecylamine Nrog CAS 124-28-7 Rau Surfactants
Cov kua nplaum xim av daj sib dua, cov khoom mos mos ntawm 20 ℃. Yaj hauv cov kuab tshuaj cawv, tsis yaj hauv dej. Los ntawm octadecylamine, formaldehyde, formic acid tau los ntawm kev sib xyaw. Ua ntej ntxiv octadecylamine rau hauv lub reactor, do kom sib npaug hauv ethanol medium, tswj qhov kub ntawm 50-60 ° C, ntxiv formic acid, do rau ob peb feeb, ntxiv formaldehyde ntawm 60-65 ° C, cua sov txog 80-83 ° C, reflux rau 2 teev, neutralize nrog kua caustic soda kom ua rau pH ntau dua 10, sawv rau stratification, tshem tawm dej, tshem tawm ethanol los ntawm kev nqus tsev distillation, thiab tom qab ntawd txias kom tau txais N, N-dimethyloctadecylamine.

Cov khoom no yog ib qho tseem ceeb ntawm cov organic synthesis intermediate ntawm quaternary ammonium ntsev hom cationic surfactant. Nws tuaj yeem ua rau 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 mos, tus neeg sawv cev antistatic, txhim kho kev sib txuas plaub hau thiab lwm yam khoom. Nws kuj tseem siv tau los tsim cov tshuaj tua kab. N, N-Dimethyloctadecylamine ua rau ethylene oxide thiab nitric acid kom tau txais octadecyldimethylhydroxyethyl quaternary ammonium nitrate, uas yog tus neeg sawv cev antistatic.
