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.
本发明涉及不饱和脂肪醇的硫酸盐和磺酸盐衍生物,其制备方法以及使用方法。在一方面,通过还原一种交换反应得到的单不饱和烷基酯来制备单不饱和脂肪醇组合物。然后,通过烷氧基化、硫酸化、磺化和亚硫酸化中的一种或多种方法将脂肪醇组合物转化为硫酸盐或磺酸盐衍生物。特别感兴趣的是硫酸盐和醚硫酸盐衍生物。
