Patent ID: 8809613

Claim:
A method for producing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of a reaction feed comprising a solvent and a homogeneous catalyst, comprising the steps of: (i) contacting ethylene with the reaction feed under oligomerization conditions and producing a reaction product comprising linear alpha-olefins the solvent and the catalyst, (ii) dosing said reaction product with at least one additive selected from the group consisting of alcohols, polyethylene glycols, polyethylene glycol monoethers, polyethylene glycol diethers, polyamines, amines, amino alcohols and surfactants, (iii) then treating the dosed reaction product with caustic to deactivate the catalyst in the reaction product, wherein the residence time of the additive in the dosed reaction product prior to treating the dosed reaction product with caustic is at least 10 seconds and does not exceed 100 seconds.
