A method is suggested to produce aldehydes by Oxo synthesis in the presence of cobalt catalyst. To provide catalyst recycling, the process is carried out in the presence of cobalt naphthenate. After reaction completion the catalyst is kept at 20-70°C and partial carbon monoxide pressure of 0.1-2 atmospheres for 0.5-2 hr for regeneration; then carbon monoxide and aldehydes are removed by known methods; the rest product containing stable slightly soluble cobalt compound is sent to Oxo synthesis stage.
