1393. ------. [I. G. FARBENINDUSTRIE, A. G.] [Preparation of Esters.] German Patent Appl. I 73,701. OZ 13,810, filed Nov. 27, 1942 (Cl. IV d-12 6). FIAT Reel 170, frames 9,617-9,620; PB 25,614; Meyer Transl. PC-S-IV, Wax Oxidation, vol. 3, chap. 39, 1949, p. 16.

In preparing esters from the unsaponifiable portions of the oxidation products of higher molecular, nonaromatic hydrocarbons, such as lignite paraffins or the hydrogenation products of CO, the fractions of the unsaponifiable constituents b. <300º under ordinary pressure are esterfied in known manner with dicarboxylic acids and the unsaponified constituents are separated. Before esterfication it is often advantageous to hydrogenate the starting material so as to convert the hydroxy compounds into alcohols. The unesterified constituents are removed from the esterfication mixture by steam distillation.
