Summary: | A process for the oligomerization of propylene is disclosed wherein a tungstated zirconia catalyst prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms useful for preparing neo acids. |
