29. ARNOLD, G. B. AND HESS, H. V. (The Texas Co.). Method for the Separation of a Heterogeneous Mixture of Compounds, United States Patent 2,539,393, Jan. 30, 1951: appl. Filed Jan. 18, 1947, Serial No. 722,844: 2 claims (Cl. 260-450).

Integrated process is given for treating a heterogeneous mixture so as to isolate organic acids in 1 fraction, aldehydes in another, ketones in another, and all alcohols in another, leaving a H₂O phase and hydrocarbon phase, both substantially free from O-containing organic compounds. Isolation of individual constituents of each class is effected by close fractionation. 2 literature refs, and 1 foreign and 7 United States patents cited.
