Williamson, Organic Experiments (D. C. Heath and Co., Lexington, Mass., 5th ed., 1983) p 332. Almost quantitative yields are obtained when 56.5 g pinacol hydrate is boiled for 3 hrs with 0.5 liter 25% H2SO4 and the product is steam distilled: Boeseken, van Tonningen, Rec. Trav. Chim. 39, 189 (1920).
