ABSTRACT:
This invention relates to a process for hydrating olefins to the corresponding alcohols in the vapour phase in the presence of a catalyst system comprising a heteropolyacid catalyst supported on niobia. By using niobia as support, it is possible not only to increase the space-time-yield of the process but also to prolong the life of the support thereby reducing the frequency with which the support is changed or replaced on a plant. The process is particularly suited to producing ethanol from ethylene and isopropanol from propylene.
