ABSTRACT:
In the process for preparing 1,7-octadiene by hydrodimerizing butadiene in the presence of a solubilized palladium or palladium compound, a tertiary phosphine, formic acid, a base and optionally a solvent, improved rates of conversions of butadiene to 1,7-octadiene are obtained by carrying out the process in the presence of supported palladium, platinum or rhodium.
