• A new group of surface active dicephalic derivatives of 1,3-dioxane, i.e., 2-alkyl-5,5-bis{[3-( N , N -dimethylamino)propyl]amido}-1,3-dioxane-di- N -oxides, were synthesized with high yields by the reaction of an appropriate 2-alkyl-5,5-bis-(carboxyethyl)-1,3-dioxane with an excess of N , N -dimethyl-1,3-propanediamine followed by oxidation with an aqueous solution of hydrogen peroxide. Structures and purity of all intermediates and final di- N -oxides were confirmed by means of 1 H-NMR and ESI-MS spectroscopy. Synthesized compounds showed high surface activity with low values of critical micelle concentration and high effectiveness of surface tension reduction ( γ CMC ). However, only derivative with the longest 2-alkyl substituent showed good foaming and moderate emulsifying properties.
