    摘要: A method is described for the preparation of 1-octene starting from butadiene, wherein in a first step (a) the bis-hydrodimerization of butadiene to 1,7-octadiene is effected in the presence of a catalyst based on palladium containing one or more tri-substituted monodentate phosphines, in an aprotic polar solvent, in a second step (b) the partial catalytic hydrogenation of 1,7-octadiene to 1-octene is effected in the presence of a titanium compound activated with one or more metal alkyls of group 13 (selected from boron, aluminum, gallium, indium).

    摘要: Acidic and salt impurities are removed from a condensed phase obtained from dimethyl carbonate synthesis by obtaining the condensed phase from the effluent of a reactor in which carbon monoxide, oxygen and methanol are reacted to form dimethyl carbonate, the condensed phase containing acid and salt impurities, and partially evaporating the condensed phase in an evaporator thereby preparing an evaporated stream substantially free of impurities and a residual bottom stream.
