アルデヒドスルホネートとアルキルベンゼン, アルキルフェノールおよびアルキルアミンの反応

抄録

Synthesis of aldehydesulfonates were tried by two methods as follows :
(A) Acetaldehydesulfonate (AS) was obtained by hydrolysis of an oximino-ethanesulfonate, prepared by oxidizing an alkali-solution of taurin with hydrogenperoxide in the presence of Na₂WO₄ as catalyst.
(B) Isobutylaldehydesulfonate (BS) was obtained by decomposing crotonaldehyde-sodiumbisulfite adduct with acid.
The reactions of AS with “alkene”, p-octylphenol and dodecyl amine, were performed. Also the reactions of BS with p-octylphenol and s-amyl-benzene were performed.
It was found that these products were surface active. It was observed that the flocculation of dispersed particules of CaCO₃ was accelerated by addition of the condensation product of BS with p-octylphenol.
