Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG C. to 200 DEG C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.

Abstract: 1. A process for separating organic iodine compounds from carbonylation products of methanol, methyl acetate and dimethyl ether or from mixtures of such carbonylation products, wherein the iodine compounds are removed by liquid phase extraction with a non-aromatic hydrocarbon.
