1450. ------. [I. G. FARBENINDUSTRIE, A. G.] (Ammoniakwerk Merseburg G. m. b. H.) [Process for Separating Alcohols From Nonaqueous Liquids.] German Patent Appl. -, filed Apr. 7. 1941. TOM Reel 134, item II-22, 11 pp., 1 fig.

Alcohols, such as those obtained from the hydrogenation of CO with H₂ are separated form the nonaqueous hydrocarbon liquids with which they are mixed by forming their boric acid esters, splitting these with H₂O, and then saponifying. Saponification of the boric acid esters is performed at elevated temperature with an aqueous solution of boric acid. On standing the mixture separates the alcohol is removed, and the boric acid is allowed to crystallize and is used again in the process. The alcohol, after separation from the mixture, is washed thoroughly with H₂O to remove the last traces of boric acid. Operation described by aid of a diagram.
