  • 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.

  • Patent number: 8993692
    Abstract: A process for polymerizing ethylene to produce an ethylene-based polymer including contacting ethylene with a Ziegler-Natta procatalyst, an alkylaluminum cocatalyst and a self limiting agent selected from the group of aliphatic, cycloaliphatic, substituted cycloaliphatic or aromatic esters, anhydrides and amides such that the self limiting agent reduces polymerization rates to no greater than 40% of the polymerization rate in the absence of the self limiting agent at temperatures equal to or greater than 120° C. is provided.

  • 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.

  • Patent number: 8434931
    Abstract: This invention is a stirrer, impeller or stirrer paddle used for mixing small volumes of liquid in a vessel having a small capacity for liquid, said impeller being characterized by an impeller blade connected to the bottom portion of a support, where the blade has an opening extending through the blade from the front to the back surface of the blade said opening extending across the rotational axis of the impeller. The invention is also an apparatus comprising that blade, a method of mixing components using the apparatus and an array of two or more of the apparatuses.
