Abstract: The hydroesterification of propylene with carbon monoxide and n-butanol (monohydric alcohols) at 160°C and in the presence of octacarbonyldicobalt functioning as a catalyst is activated mainly by ß- and y-picoline while α-picoline, lutidines, and collidines are practically inactive. According to their activation effect, the bases investigated may be arranged in the sequence β-picoline ≥ pyridine ≥ γ-picoline > quinoline > α-picoline, lutidines. Mono-, di-, and triethanolamine as well as ammonia have only retardation effect. On the other hand, β-picoline has a distinct retardation effect provided glycols have been used for the hydroesterification of propylene instead of monohydric alcohols.
