Abstract

The surface tension and foaming properties of sodium oleate were altered by adding a large and electronegative moiety bromine, to its unsaturation. These properties were measured and compared to the original oleic soap. It was found that sodium oleate has a lower CMC than both of the brominated surfactants. The bromine moiety slows down the rate of adsorption with the doubly brominated surfactant being the slowest. Foamability of the brominated analogues were not affected, however its foam were found to be less stable. Bromination also caused the coalescence and bursting of large bubbles.
