N-アルキル-N'-グルコノイルエチレンジアミンの合成ならびに界面活性

抄録

N-alkyl-N'-gluconoylethylenediamine was synthesized almost quantatively by the reaction of δ-gluconolactone with N-alkylethylenediamine.
As they were expected to have surface activity, the authors measured the lowering ability of surface and interfacial tension and the foaming power of the water solution of the N-alkyl-N'-gluconoylethylenediamines and their hydrochlorides that have C₈C₁₈ carbon atoms in the alkyl chain.
Authors found that the surface active properties of N-octyl, N-decyl and N-dodecyl-N'-gluconoylethylendiamine and their hydrochlorides were satisfactory, and the lowering ability of the surface tention of N-dodecyl derivative was good for wide range of pH.
