    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.

    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.
