FIELD: production of oxo-products. SUBSTANCE: propylene flow containing propane as impurity is subjected to reaction with carbon monoxide and hydrogen in the presence of hydroformilation catalyst that results in obtaining of flow of products containing butyraldehyde and/or n-butyl alcohol, unreacted propylene and propane. Gas mixture containing propylene and propane is separated from the flow of products and subjected to adsorption at temperature of 0 to 250 C in a layer of adsorbent which selectively adsorbs propylene that results in adsorption of practically all propylene from the gas mixture. Propylene is desorbed from adsorbent and returned to the reaction zone. Process is conducted at low conversion stage with return of unreacted propylene. Propylene adsorption unit, according to the invention, may be in the top or bottom part of hydroformilation reactor. EFFECT: higher efficiency. |
