The present disclosure relates to a method for recycling a taurine mother liquor, which includes: adding a base to the taurine mother liquor, heating to a first temperature, carrying out a hydrolysis reaction, removing ammonia produced, and evaporating and concentrating the ammonia-removed solution to obtain an alkali metal hydroxyethyl sulfonate solution. When applying the method provided by the present disclosure for the recycling of the taurine mother liquor, the taurine mother liquor can be further converted into the alkali metal hydroxyethyl sulfonate solution, impurities are removed from the obtained alkali metal hydroxyethyl sulfonate solution, the impurity-removed alkali metal hydroxyethyl sulfonate solution is concentrated and crystallized, and the alkali metal hydroxyethyl sulfonate is separated out. The method provided by the present disclosure is an efficient and simple method for recycling the taurine mother liquor, which is very easy to implement industrially and can effectively recycle the taurine mother liquor.

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.
