1525. ------. [I. G. FARBENINDUSTRIE, A. G.] [Purifying Synthetic Alcohols.] British Patent 311,468. Feb. 16. 1928. Chem. Abs., vol. 24, 1930. p. 861.

Alcohols such as methyl or iso-Bu alcohol obtained catalytically from H₂ and C oxides are purified by use of oxidizing agents such as KMnO₄, H₂O₂, persulfates, percarbonates, or hypohalites, followed by distillation. Organic bases or fixing agents such as ZnCl₂ may be added in small quantities, and auxiliary purifying agents may also be used such as NaOH, NaHSO₃, or oxalic acid.
