Process for producing low polymer of alpha-olefin |
摘要 |
A process for producing an alpha-olefin oligomer by oligomerization of an alpha-olefin in a presence of a Ziegler-based catalyst, the process comprising introducing at least a portion of a reaction product which is taken out of a reactor and has a temperature of 115° C. or higher into an external heat exchanger, cooling the introduced reaction product, maintaining an oligomerization solution taken out of the external heat exchanger at a temperature of 110° C. or higher and returning at least a portion of the oligomerization solution to the reactor. In the production of an alpha-olefin oligomer, precipitation and adhesion of polymers at the inside of manufacturing apparatuses such as the external heat exchanger and troubles caused thereby can be prevented and a stable continuous operation can be continued for a long time.
