Abstract: PROBLEM TO BE SOLVED: To provide a distillation column having high separation efficiency, in which the vapor amount is made constant all over the column including a feed section and a side steam take-off section.
SOLUTION: Partition walls DW are arranged substantially along the longitudinal direction of the distillation column so that the inside of the distillation column is divided into an upper zone 2 and a lower zone 4 of the feed section, an upper zone 3 and a lower zone 5 of the side stream take-off section, an upper common column section 1 and a lower common column section 6. A feeding mixture to be separated between the zones 2 and 4 of the feed section is in a wholly or partially vaporized state and/or the side stream to be taken off from the zones 3 and 5 of the side stream take-off section is in a wholly or partially vaporized state.

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: 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: Columna para la puesta en práctica de destilaciones reactivas en presencia de un catalizador heterogéneo en forma de partículas, con una empaquetadura formada por chapas de empaquetadura que forman cavidades en el espacio interior de la columna, caracterizada porque la columna presenta primera y segunda zona parcial, que están dispuestas alternantemente, y se diferencian en la superficie específica de las chapas de empaquetadura, de tal manera que en las primeras zonas parciales el cociente de diámetro hidráulico para la corriente gaseosa a través de la empaquetadura y el diámetro equivalente de partículas de catalizador se sitúa en el intervalo de 2 a 20, preferentemente en el intervalo de 5 a 10, de modo que las partículas de catalizador se pueden introducir en las cavidades, distribuir y descargar sueltas bajo acción de la fuerza de gravedad, y porque en las segundas zonas parciales el cociente de diámetro hidráulico para la corriente gaseosa a través de la empaquetadura y el diámetro equivalente de partículas de catalizador es menor que 1, y porque en las segundas zonas parciales no se introducen partículas de catalizador.

Abstract: The invention relates to a column for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst, with a packing or filling bodies, which form cavities in the column interior. The quotient for the hydraulic diameter for the gas stream through the packing or filling bodies and the equivalent diameter of the catalyst particles lies in the range of 2 to 20, preferably in the range of 5 to 10, whereby the catalyst particles are introduced loose into the cavities, distributed and removed under the influence of gravity.
