Title:
線状アルファオレフィンの改良乾燥方法
Document Type and Number:
Japanese Patent JP2009504579
Kind Code:
A
Abstract:
The present invention relates to a method for preparing linear alpha-olefins by oligomerisation of ethylene, comprising the steps of:
(i) oligomerising ethylene in a reactor in the presence of a solvent and a catalyst;
(ii) transferring a liquid organic outlet stream of the reactor, containing solvent, catalyst, dissolved ethylene and linear alpha-olefins, to a catalyst deactivation section;
(iii) deactivating the catalyst by washing the outlet stream with an aqueous basic phase to obtain a deactivated catalyst containing aqueous phase and a water saturated organic phase;
(iv) separating the aqueous phase and the organic phase from step (iii);
(v) transferring the water saturated organic phase to a distillation column;
(vi) distilling the water saturated organic phase; and
(vii) separating the distilled organic and aqueous phases.
