processo para telomerização de butadieno

preparo de precursor de catalisador de telomerização de butadieno uso de uma mistura de solvente que contém 1-metoxi-2,7-octadieno e alcanóis ao invés de alcanóis por si mesmos para preparar um precursor de catalisador adequado para uso na telomerização de butadieno. The invention relates to a process for preparing a telomerization catalyst precursor used in telomerization of butadiene that comprises dissolving one equivalent of palladium acetyl acetonate and from one to three equivalents of a tertiary phosphine ligand in a solvent that comprises methanol and, optionally, 1-methoxy-2,7-octadiene under conditions sufficient to yield a catalyst precursor solution wherein the tertiary phosphine ligand is represented formulaically as R1PR2 and where R1 is an aryl moiety or a substituted aryl moiety or an alkyl moiety or heteroatom-containing alkyl moiety with 1 to 12 carbon atoms, and R2 is independently a heterocyclic oxaadamantyl group.
