Document Type and Number:
Japanese Patent JP3841361
Kind Code:
B2
Abstract:

PURPOSE: To obtain a process for the production of an α-olefin oligomer such as 1-hexene in high yield and selectivity and especially capable of improving the purity of the obtained α-olefin oligomer by removing the catalytic component such as chromium compound from the reaction liquid.
