Abstract
Alkyl norbornyl ether sulfonates are prepared by reacting, for example, an allyl alcohol ethoxylate with an alkyl norbornene in the presence of an acid catalyst. The allyl ethers so obtained are subsequently sulfonated. These compounds, which exhibit a high degree of detergency, are useful for solubilizing petroleum sulfonates in oil fluid brine solutions.
