A homologous series of fluorescent surface-active compounds were synthesized. The methods of syntheses were as follows; A series of n-alkylamines of C4C16 alkylchain, even in the carbon number, was reacted with methyl-acrylate, and the product was hydrolyzed with sodium hydroxide.
The compound obtained was then reacted with p-phenylphenacylbromide in ethanolic acetate buffer solution to give C4H9NHCH2CH2COOCH2COC6H4C6H5 to C16H33NHCH2CH2COOCH2COC6H4-C6H5, all of which were purified by repeated recrystallisation from ethanol.
The products were obtained in a form of yellowish flakes which were identified by IR and UV absorption spectra. The lowering of the surface tension in dilute acid solution was not appreciable for the lower members, while the higher members had strong foaming ability and showed remarkable lowering of the surface tension. All members showed fluorescence.
