  • Patent number: 9174905
    Abstract: A process for the telomerization of butadiene comprises reacting 1,3-butadiene and an alkanol, in the presence of a catalyst promoter and an alkoxydimerization catalyst comprising a Group VIII transition metal and a triarylphosphine ligand, which includes one phenyl that is mono-ortho-alkoxy substituted and at least one other phenyl including at least one substituent that withdraws electrons from the phosphorus atom. The product includes an alkoxy-substituted octadiene, which may then be used to produce 1-octene. The catalyst shows improved stability, activity and selectivity toward the alkoxy-substituted octadiene.
    Type: Grant

  • Patent number: 8558030
    Abstract: In an improved process for telomerizing butadiene, contact butadiene and an organic hydroxy compound represented by formula ROH (I), wherein R is a substituted or unsubstituted C1-C20-hydrocarbyl and the organic hydroxy compound is not glycerol, in a reaction fluid in the presence of a palladium catalyst and a phosphine ligand represented by formula PAr3 (II), wherein each Ar is independently a substituted or unsubstituted aryl having a hydrogen atom on at least one ortho position, at least two Ar groups are ortho-hydrocarbyloxyl substituted aryls. The phosphine ligand has a total of two (2), three (3), four (4), five (5), or six (6) substituted or unsubstituted C1-C20-hydrocarbyloxyls, and optionally, any two adjacent substituents on an Ar group can be bonded to form a 5- to 7-membered ring.
