Abstract: A process for producing alpha-olefins comprising contacting an ethylene feed with an oligomerization catalyst system in an oligomeriation reaction zone under oligomerization reaction conditions to produce a product stream comprising alpha-olefins wherein the catalyst system comprises a metal-ligand complex and a co-catalyst and the oligomerization reaction conditions comprise a reaction temperature of at least 115° C.

Abstract: A method of producing alcohol alkoxylates comprising contacting a hydrocarbon mixture with a hydroformylation catalyst under hydroformylation conditions to form a product mixture comprising one or more alcohols and formate esters; treating the product mixture to reduce the concentration of formate esters to produce an alcohol stream; and contacting the alcohol stream and an epoxide with a potassium hydroxide catalyst under alkoxylation conditions to produce one or more alcohol alkoxylates.

Abstract: A process for producing alpha-olefins comprising contacting an ethylene feed with an oligomerization catalyst system in an oligomerization reaction zone under oligomerization reaction conditions to produce a product stream comprising alpha-olefins wherein the catalyst system comprises an iron-ligand complex and a co-catalyst and the molar ratio of oxygen to iron being fed to the oligomerization reaction zone is of from 1:1 to 200:1. Alternatively, the molar ratio of oxygen to aluminum in MMAO being fed to the oligomerization reaction zone is less than 1:5.

Abstract: A process for producing alpha-olefins comprising: a) contacting an ethylene feed with an oligomerization catalyst system in an oligomerization reaction zone under oligomerization reaction conditions to produce a product stream comprising alpha-olefins; and b) cooling at least a portion of the reaction zone using a heat exchange medium having an inlet temperature and an outlet temperature wherein the catalyst system comprises a metal-ligand complex and a co-catalyst; the oligomerization reaction conditions comprise a reaction temperature of greater than 70° C.; and the difference between the reaction zone temperature and the inlet temperature of the heat exchange medium is from 0.5 to 15° C.
