Abstract: A mixture of sulfates is made by dimerizing one or more even numbered alpha olefins to produce one or more vinylidenes; hydroformylating the vinylidene(s) to produce a mixture of alcohols; and sulfating the mixture of alcohols to form alcohol sulfates. The sulfates are useful in laundry detergents and other surfactants.
