The four butanols were converted into C₅ homologous alcohols in the presence of cobalt-ruthenium binary catalysts.The behaviour of each alcohol was examined againts catalyst composition and promoting agent.The best results were obtained with Co/Ru molar ratios close to 5.The chain-lengthening mechanism is supposed to involve an olefinic intermediate (at least for s- and t-butanol) which is subsequently hydroformylated.The cocatalytic effect of ruthenium is, however, still unclear.
