Alcohol and/or aldehydes are prepd. by hydroformylation of olefins with Co and H2 at 20-250 degrees C over a catalyst with repeat units Z - O - i - Q (where Z is pref. derived from SiO2) esp. of formula (where R1R2 = 1-10C alkyl (oxy) or aryl (oxy). R3R4= 1-10C alkyl or aryl; R5 = 1-24C opt. subst. alkylene or arylene; M = Rh, Ir or Co; L = ligand; m = digit to satisfy free valencies of M). |
