Abstract:

Brominated surfactants are prepd. by the complete bromination of the double bonds in the hydrophobic chains of the oleic acid [112-80-1], linoleic acid [60-33-3], Span 80 [1338-43-8], Span 85 [26266-58-0], Tween 80 [9005-65-6], and Tween 85 [9005-70-3]. The addn. of Br increases the sp. gr. of the surfactant mol. to values above that of water, allowing the formation of oil-in-water emulsions with denser droplets, i.e., the surfactants are emulsifiers and weighting agents. The surfactant properties of the brominated surfactants are discussed. [on SciFinder(R)]
