Abstract: A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.

Abstract: Column with packing is used for distillation/reactive distillation of mixture with toxic component(s). Packing layer(s) has upper and lower end, with variable internal geometry over height (H). Lower zone (6) of packing layer, with higher flow resistance, gives bubbling layer with mainly dispersed gas phase and upper zone (7) develops film flow with mainly continuous gas phase. Column with a packing is used for the distillation or reactive distillation of a mixture, with at least one toxic component. At least one packing layer has an upper and a lower end, with a variable internal geometry over its height (H). The lower zone (6) of the packing layer, with a higher flow resistance, gives a bubbling layer with a mainly dispersed gas phase and, at the same time, the upper zone (7) develops a film flow with a mainly continuous gas phase.

Abstract: A process for preparing a compound of the formula Iwhere R1 and R2 are hydrogen or C1-C4-alkyl and R3 is C1-C10-alkyl, phenyl or C1-C4-alkyl-substituted phenyl, comprises reacting a compound IIwith a compound of the formula IIIwhere X is chlorine, bromine or iodine, in the presence of a Friedel-Crafts catalyst in one step to give a compound I.

Abstract: Compounds of the general formula I in which R is H or C1-C4-alkyl, R is C1-C4-alkyl and R is an ether, silyl ether or acetal protective group which can be converted into a hydroxyl group by hydrolysis, in particular one of the radicals and a process for the production of these compounds by reacting an alkenyne of the general formula II in an inert solvent with additional use of lithium amide with a cyclohexenone of the general formula III and the use of the compounds of the formula I for the production of astaxanthin.
