Abstract
The following three compounds, sodium N- (p-hydroxybenzyl) -fatty acid amide sulfonate (R7, R11 and R15) were prepared,
_??_
R : n-C7H15 (R7), n-C11H23 (R11), n-C15H31 (R15)
The physico-chemical properties of the aqueous solution of these compounds were studied by specific gravity, surface tension, electroconductivity, dispersability of CaCO3 and wettability to the cloth, etc. It was found that the surface activities of these compounds was not high except the dispersion ability of R11.
