Abstract: Process for the production of stable dry powders which are insoluble in hot water and which contain fat-soluble vitamins and/or carotenoids, which comprises the following process steps: a) preparation of an aqueous dispersion containing essentially these fat-soluble active substances, film-forming colloids and reducing sugars, b)conversion of this dispersion into dry powders of vitamin and/or carotenoid products and c) thermal hardening of the powder at temperatures of 60 to 180 DEG C, and which is characterised in that gelatin in combination with one or more organic amino compounds which are free or bound as salts and which contain a basic primary amino group and additionally either another amino group, a hydroxyl group, an alkoxy group or a carboxyl group, and/or in combination with sufficient basic alkali metal or alkaline earth metal compound for the dispersion to have a pH of 7.5 to 10, is used as film-forming colloid, and the dry powders obtainable by this process are described.

Abstract: Prodn. of polyenecarbonyl cpds. (I) having high all-E content, and their acetals and ketals, comprises reacting a carbonyl cpd. (II) with a dialkyl phosphonate in a Horner-Emmons reaction or with a CH-acidic cpd. in an aldol condensation in the presence of 0.3-10 mol.% (based on (II)) of a component (B) comprising a) oxygen or nitrogen monoxide (opt. mixed with an inert gas); b) the stable 2,2-diphenyl-1-picrylhydrazyl radical or a hydrogen peroxide-urea adduct; c) quinone, a quinone deriv. or coenzyme Q10 hydroquinone; and/or d) a stable radical of formula (I) or (II). R1, R2 = 1-4C alkyl; or R1+R2 = ethylene, propylene, vinylene or propenylene (all opt. substd. by alkyl, aryl, OH, alkoxy, silyloxy, oxo, NH2, SH, alkylthio, CN, COOH, carbamoyl, heteroaryl or alkylcarbonyloxy); R3-R5 = as R1, R2.

Abstract: The invention relates to a method for producing enol ethers of formula (I), in which R is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical, which radicals can carry other substitutes that do not react with acetylenes or allenes; the R radicals are, independently of each other, hydrogen, or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which can interconnect forming a ring; and m stands for 0 or 1. In this method, acetals or ketals of formula (II) are reacted with acetylenes or allenes of formula (III) or (IV), in which the R and R radicals have the aforementioned meanings. The reaction takes place in the gas phase, at high temperature, in the presence of a heterogeneous catalyst containing zinc or cadmium together with silicon and oxygen.
