Synthesis of Brominated C-18 Fatty Acids and Surfactant Properties of Their Sodium Salts

The physicochemical properties of sodium salts fatty acid have not been thoroughly investigated and are, therefore, not well understood In line with this, brominated and non-brominated sodium salts of C-18 chain fatty acids were prepared and their physicochmical properties and performance in aque...
