Title:
PRODUCTION OF 1-HEXENE
Document Type and Number:
Japanese Patent JP3890628
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To produce 1-hexene without separating the by-product from the system or causing the clogging of the apparatus by trimerizing ethylene in the presence of a chromium-based catalyst, deactivating the catalyst, introducing water into the treating system and stirring the mixture to effect the deashing treatment.
SOLUTION: Ethylene is trimerized in the presence of a chromium-based catalyst composed of a chromium compound and an alkyl metal compound and the chromium-based catalyst is deactivated after completing the trimerization reaction. Water is introduced in an amount of 20-200vol.% based on the liquid reaction product into the treating system while keeping the liquid reaction product at 100-180°C and the system is stirred with a stirring power of ≥1KW/m3 to effect the deashing treatment by the removal of the metallic component originated from the chromium-based catalyst from the liquid reaction product and obtain 1-hexene useful as a comonomer of a linear low-density polyethylene or a raw material for plasticizers.
