Idemitsu Petroleum

Idemitsu A process for making C6-C18 a-olefins from ethylene, catalyzed by a modified homogeneous Ziegler-Natta catalyst containing a zirconium chloride. Developed by the Idemitsu Petroleum Company in 1988. 

A somewhat different application of SCFs in separation is the industrial process for the production of butan-2-ol from sc-Butene. This process, operated by the Idemitsu Petroleum Company has been described in some detail elsewhere [1]. Briefly, the reaction between butene and H2O takes place in an aqueous phase. sc-Butene is only partially miscible with H2O and an equilibrium is set up between butene and butan-2-ol in the aqueous phase but, under these conditions, butan2-ol is more soluble in sc-Butene than in H20.
