Abstract:
Process for the preparation of 1-octene, comprising:a) reacting 1,3-butadiene with a compound containing an active hydrogen atom, wherein said compound is selected from the group consisting of alkanols, hydroxy-aromatic compounds, carboxylic acids, ammonia, primary amines, secondary amines, and water, in the presence of a telomerization catalyst based on (1) a source of group VIII metal, (2) a bidentate ligand â€ƒwherein the bidentate ligand has the general formula I R1R2M1â€”Râ€”M2R3R4â€ƒâ€ƒ(I) â€ƒwherein M1 and M2 are independently P, As or Sb; â€ƒR1, R2, R3 and R4 independently represent a monovalent aliphatic group; â€ƒor R1, R2 and M1 together and/or R3, R4 and M2 together independently represent an optionally substituted aliphatic cyclic group with at least 5 ring atoms, wherein one ring atom in said cyclic group is M1 or M2, â€ƒand R represents a bivalent organic bridging group, thereby producing 1-substituted-2,7-octadiene; b) hydrogenating the 1-substituted-2-7-octadiene of step a) thereby producing 1-substituted octane; c) decomposing the 1-substituted octane of step b) and thereby producing 1-octene.
