✦ Synopsis

Propene was oligomerized at 5000 kPa and 250°C at 5 and 50% conversion. Equilibrium concentrations for the hexene isomers were predicted using data from various sources. The data from the NBS gave the best equilibrium prediction. Comparsions between the low and high conversion results and also with equilibrium predictions indicate that at low conversions the system attains equilibrium with respect to double bond isomerization but not with respect to the skeletal structures. At the low conversion conditions chosen only oligomerization reactions occurred. All this supports the development of a model for oligomerization based on skeletal groups at each carbon number.

It is shown that, at low extent of reaction. molecular hydrogen 130-260 torr) improves the selectivity of the thermal reaction of propene (30-200 torr), around 800 K, by increasing the rates of production of methane, ethene, and propane whereas it has no effect on those of al-Iene and 4-methylpent-l

## Abstract We describe an efficient numerical procedure for the equilibrium solution of the internal electric field distribution resulting from poling of photo‐refractive materials. This technique has been developed to model the equilibrium state in poled bulk devices requiring bulk charge neutral
