Abstract: A process is described for preparing tetrahydrogeranylacetone in which pseudoionone, geranylacetone and/or dihydrogeranylacetone in a liquid phase, in which particles of a catalyst which is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds are suspended, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.

Abstract: Continuous isolation of 2 stereoisomeric isoprenoid alcohols (IA, IB) from crude mixture by rectification involves feeding crude mixture into side of feed column coupled with discharge column(s) and discharging (IA) and (IB) from discharge column(s), columns being coupled in such way that there is no cross-mixing of vapor and condensate between feed column and discharge column(s), at least in (I) discharge region.

Abstract: In continuous isolation of alpha,beta-unsaturated aldehyde (I) by rectification, crude mixture is fed into feed column above concentration zone (C) and below separation zone (S). Upper combining column (U) and lower combining column (L) with bottom heater communicate with top of C and bottom of S respectively and with discharge column (D). (I) is discharged from side of D and lower and higher boiling compounds respectively from top of U and sump of L.

Abstract: A process for recovering crude 1,3-butadiene from a C 4 fraction by extractive distillation using a selective solvent in a dividing wall column (TK) in which a dividing wall (T) is arranged in the longitudinal direction of the column to form a first subregion (A), a second subregion (B) and a lower common column region (C) and which is preceded by an extractive scrubbing column (K) is proposed.

Abstract: A process for obtaining pure 1,3-butadiene from crude 1,3-butadiene by distillation is carried out in a dividing wall column in which a dividing wall is located in the longitudinal direction of the column to form an upper common column region, a lower common column region, a feed section and an offtake section.

Abstract: FIELD: methods of catalytic distillation. SUBSTANCE: method includes combination of heterogeneous catalytic reaction with simultaneously conducted distillation or rectification on catalyst layer. Process is carried out on catalyst layer produced by spray-coating and/or cathode sputtering at least of one active substance in capacity of catalyst and/or promoter onto cloth, weave or foil as carrier, and also reactor for catalytic distillation. EFFECT: produced yield at constant level due to more stable process conduction. 12 cl

Abstract: Preparation of unsaturated ketones by reaction of the corresponding alpha , beta -unsaturated alcohol with an alkyl acetoacetate compound in the presence an organo-aluminum catalyst at constant temperature, with separation and continuous removal of CO2 and alcohol formed. Preparation of unsaturated ketones of formula (I) by reaction of the corresponding alpha , beta -unsaturated alcohol of formula (II) with an alkyl acetoacetate compound of formula (III) in the presence of 0.1-5 mole% (based on (III)) of an organo-aluminum catalyst with separation and continuous distillative removal of CO2 and alcohol of formula R3OH formed during reaction, in a reactor containing a fractionation column, where: (A) (II) is added to the reaction mixture together with the organic catalyst without additional solvent and (III) is then added to this mixture; (B) the reaction temperature is kept constant between 175-220 degrees C; (C) the content of (III) is kept at a constant level between 0.1-10 wt.% during the reaction. R1, R3 = 1-4C alkyl; R2 = 4-30C aliphatic, cycloaliphatic or cycloaliphatic-aliphatic; a, b = optional additional bonds.
