2080. LUTHER, M. (I. G. Farbenindustrie A. G.). [Oxidation Products of Paraffin Wax.] German Patent 535,068, August, 4, 1929. Chem. Abs., vol. 26, 1932, p. 1434.

Oxidation products of solid aliphatic hydrocarbons are separated from unaltered hydrocarbon by centrifuging at a temperature at which the hydrocarbon remains solid. Separated mixtures of the oxidation products may be fractionated by centrifuging at a temperature < the melting point of the mixture. Examples are given.
