Description

The codimerization of ethylene with' propylene catalyzed by potassium was carried out at 130°C in heptane to give 1-pentene as a major product. Addition of carriers such as Cu, K2CO3 and KCl powder increased the yield of 1-pentene as well as the reaction rate. Addition of potassium butoxide as an additive was effective but that of tributylamine was not so effective in the reaction in contrast to the case of potassium-catalyzed dimerization of propylene, in which both additives were effective. Octylpotassium was found to be a very effective catalyst for the selective formation of \J-pentene, and Potassium. -octyl chloride catalyst also gave a simmilar result.
