Abstract：
 The present invention relates to the process of producing isononyl aldehyde from mixed octane and synthetic gas in the presence of Co/phosphine oxide catalyst, and belongs to the field of fine petrochemical industry. The present invention features that the Co/phosphine oxide catalyst system with Co compound as catalyst precursor and phosphine oxide as catalyst ligand; the synthetic gas is mixture of CO and H2 in the CO/H2 ratio of 1; and isononyl aldehyde is prepared from mixed octane and synthetic gas in the mild condition including reaction temperature of 120-200 deg.c and synthetic gas pressure of 4-20 MPa. The present invention has simple technological process, low cost, mild reaction condition and high yield of isononyl aldehyde product, and is suitable for industrial production.
