Cov kua nplaum xim av daj sib dua, cov khoom mos mos ntawm 20 ℃. Yaj hauv cov kuab tshuaj cawv, tsis yaj hauv dej.

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 ntau yam quaternary ammonium ntsev cations, uas tuaj yeem siv rau hauv cov ntaub softening tshuaj, antistatic agent, txhim kho cov plaub hau combing zog 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 los tsim octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate, piv txwv li antistatic agent SN.
