Abstract: A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.

Abstract: Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R and R are alkyl or R and R and the common C atom are 5-membered to 7-membered cycloalkyl; R is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.

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.
