PROCESS FOR MAKING A LINEAR ALPHA-OLEFIN OLIGOMER USING A HEAT EXCHANGER

摘要

The invention pertains to a process for making a linear alpha-olefin oligome r in a reactor comprising a liquid and a gas phase, comprising the steps of catalytically oligomerizing ethylene in the presence of an iron complex of , a 2,6-bis (arylimino)pyridine derivative, to the alpha-olefin oligomer with an average molecular weight between 50 and 350 under release of heat, and removing the heat with a heat exchanger, which is not in direct contact with the liquid phase, using at least part of the gas phase as a coolant medium. The invention further relates to an apparatus to perform said process.
