Abstract[English]
A process for the production of 2-alkylalkanol is described. The process comprises : providing a mixed aldehyde stream comprising iso-aldehyde and normal-aldehyde through a process comprising hydroformylation of an olefin; passing the mixed aldehyde stream to an isomer column for separation of iso- aldehyde from normal-aldehyde; withdrawing a first liquid normal-aldehyde stream from a first position in the isomer column; withdrawing a second liquid normal-aldehyde stream from a second position in the isomer column such that the second liquid normal-aldehyde stream has a greater concentration of heavies than the first liquid normal aldehyde stream; and sending at least part of the first liquid normal aldehyde stream to an 2-alkylalkanol production process comprising aldolization of normal-aldehyde to 2- alkylalkenal and hydrogenation of the 2-alkylalkenal to 2- alkylalkanol.[French]
L'invention concerne un procédé de production de 2-alkylalcanol. Le procédé comprend : la fourniture d'un flux d'aldéhyde mélangé comprenant de l'iso-aldéhyde et un aldéhyde normal par l'intermédiaire d'un procédé comprenant l'hydroformylation d'une oléfine ; le passage du flux d'aldéhyde mélangé vers une colonne d'isomération pour la séparation de l'iso-aldéhyde à partir d'aldéhyde normal ; le retrait d'un premier flux d'aldéhyde normal liquide d'une première position dans la colonne d'isomère ; le retrait d'un second flux d'aldéhyde normal liquide d'une seconde position dans la colonne d'isomère de telle sorte que le second flux d'aldéhyde normal liquide a une concentration de composés lourds supérieure à celle du premier flux d'aldéhyde normal liquide ; et l'acheminement d'au moins une partie du premier flux d'aldéhyde normal liquide vers un procédé de production de 2-alkylalcanol comprenant l'aldolisation d'aldéhyde normal en 2-alkylalcénal et l'hydrogénation du 2-alkylalcénal en 2-alkylalcanol.
