Activation of cobalt preformer catalyst for oxo process

摘要

Noble metal or other preformer catalysts used to convert cobalt salts to hydrido cobalt carbonyl for use in the oxonation of olefins are activated or regenerated by treatment with H2O at 120 DEG to 170 DEG C., 13.78 MPa (2,000 psig) to 31.00 MPa (4,500 psig) for 2-50 hours.
