3095. -----[RUHRCHEMIE, A.G.] [Process for Separating Mixtures of Sulfuric Acid Esters of High-Molecular Hydrocarbons on the One Hand and Paraffin Hydrocarbons on the Other.] German Patent Appl. --, R 707, filed Mar. 10, 1944 (Cl. IV d-12 o). TOM Reel 37, bag 3,451, item 36, 3 pp.

In the further development of the process described in German Patent Appl. R 116,698 (abs. 3096), after neutralizing the esters with alkali or earth alkali hydroxides, finely pulverized inorganic or organic substances, such as talc, soda, or starch together with H₂O, are added and the mixture is heated for a few hours at 30°-90°, preferably 30°-50°.
