Conclusions 1. The oven drying method for the determination of water in sodium alkyl aryl sulfonates results in incomplete removal of water and may result in the loss of unsulfonated oil and other volatile products. 2. The determination of water in sodium alkyl aryl sulfonates by desiccation over concentrated sulfuric acid results in incomplete removal of the water. 3. The determination of water in sodium alkyl aryl sulfonates by azeotropic distillation and subsequent measurement of the water distilled is not recommended because of the operational difficulties and lack of sufficient accuracy. 4. The azeotropic distillation of Suter (6) is applicable for the determination of water in sodium alkyl aryl sulfonates, but comparable results may be determined more readily by the proposed Karl Fischer method. 5. The determination of water in sodium alkyl aryl sulfonates by the Karl Fischer method is the most satisfactory of the methods investigated.
