Abstract: PROCESS FOR CODIMERIZING OLEFINSThe present invention relates to a process for preparing olefin codimers by converting a first and second olefin starting material over a heterogeneous olefin oligomerization catalyst, to the olefin codimers obtainable by this process, to a process for preparing alcohols, in which such olefin codimers are subjected to a hydroformylation and subsequent hydrogenation, to the alcohol mixtures thus obtainable and to their use.(No suitable figures)

Abstract: In a nickel-catalysed method for the oligomerization of 4-8C alkenes in a series of 2 or more reactors operating under adiabatic conditions, the feed stream is split and the part-streams are fed into at least 2 of the reactors with the addition of fresh feed so that the temperature in any reactor is not more than 20[deg]C above that in any of the other reactors. A method for the production of oligomers of 4-8C alkenes from a hydrocarbon feed stream containing such alkenes, on a nickel-containing heterogeneous catalyst in a series of 2 or more reactors operating under adiabatic conditions at 30-280[deg]C and 1-300 bar, where: (a) the feed stream is introduced into reaction zone 1 at a temperature T1, (b) the temperature increases in each zone, and (c) if this increase is more than T1 + 20[deg]C, the temperature is adjusted to within the range T1 +- 20[deg]C before the mixture is fed into the next zone. In this method, the feed stream is split and the part-streams are fed into at least two of the reactors with the addition of fresh feed so that the temperature in any one reactor is not more than 20[deg]C above that in any of the other reactors.

Abstract: A process for preparing phthalic anhydride by gas-phase oxidation of xylene, naphthalene or mixtures thereof over two different fixed-bed catalysts arranged in zones in a shell-and-tube reactor which is thermostated by means of a heat transfer medium is carried out so that the maximum temperature in the second catalyst zone in the flow direction is at least 52° C. lower than the maximum temperature in the first catalyst zone.The process of the present invention makes it possible to prepare phthalic anhydride in high yields under conditions relevant to industrial practice.
