Abstract
Novel cationic gemini surfactants, bis(ester-ammonium) dichlorides having a butenylene or a butynylene spacer and an oxycarbonyl group in the lipophil ic part, were prepared conveniently and almost quantitatively by the reacti on of the corresponding mono(ester-amine) with a highly reactive allylic- o r propargylic dichloride. Most of these surfactants showed excellent surfac e-active properties and good biodegradability. The effects of the structure of spacer, the position of the oxycarbonyl group in the lipophilic part, t he alkylene length between the oxycarbonyl and the ammonio groups, and the acyl chain length of the surfactants on their surface-active properties wer e examined.
