Zusammenfassung:Un derivado de sulfato que tiene la estructura general: R-CH = CH-(CH2)7-CH2O-(AO)n-SO3X en la que R es h o alquilo C2; X es un catión mono o divalente o un amonio o catión de amonio sustituido; AO es un grupo oxialquileno; y n, que es el número promedio de grupos oxialquileno, tiene un valor dentro del rango de 0 a 200, en la que cuando R es alquilo C2, el derivado de sulfato tiene al menos 1 % mol de insaturación trans-Δ9. Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed. The derivatives and sulfate compositions are valuable for many end-use applications, including, for example, agricultural dispersants, water-soluble herbicides, anionic emulsifiers for agricultural use, hard surface cleaners, light-duty liquid detergents, personal cleansers, gas well foamers for oilfield applications, laundry detergents, enhanced oil recovery compositions, latex paints, and specialty foams.
