Abstract
Novel lithium dicyclopentadienyl titanium hydride type compositions are described, useful as catalysts in converting ethylene to 1-butene, which is used in producing "polymer gasoline" for increasing the octane number of automotive gasolines. Methods for synthesizing the novel compositions are also described.
Claims7
A composition of matter of the formula:
- LiRR'TiH, wherein R and R' are cyclopentadienyl rings of the empirical formula, C.sub.5 H.sub.5, wherein the ring hydrogens may be independently substituted with one or more groups inert toward lithium metal, said rings being bonded to titanium by sigma-bonds, pi-bonds or mixtures thereof, and said composition exhibiting a .sup.13 C nuclear magnetic resonance spectrum in deuterated benzene, in which observed values for the chemical shifts of the ring carbons in R are different from the observed values for ring carbons in R', and said composition exhibiting an infrared spectrum in deuterated n-hexadecane in which a titanium metal-hydride absorption band is observed in the region of about 1250-1450 cm.sup.-1.
