Definitions

• beryllium, aluminium, gallium and indium compounds of the types BeR AIR;, and InR in which at least one of the ligands, R, represents an organic hydrocarbon residue of hydrogen, are able to convert lower olefines to dimerized, trimerized and higher products with high alpha-olefine content, and that the presence of finely powdered metallic cobalt, nickel or platinum increases the selectivity of the systems favouring the formation of more low-molecular (dimerized) products.
• finely powdered metallic nickel in the form of Raney nickel additions or metallic nickel reduced from nickel compounds by conversion with a certain amount of the organic main group metal component at higher temperature has been used.
• a characteristic feature of the said processes, in which transitional metal additions are used as co-catalyst, is that these exist in finely powdered metallic form with the formation of a heterogenous phase in the catalytic mixtures.
• organic ligands preferably such containing one or more carbon/carbon double or triple bonds
• Compounds which contain such types of bonds are termed 1r-organic transition metal compounds.
• Common to the types of organic nickel compounds indicated above is that these contain 1r-b0nd6d organic ligands. Since other nickel organic compounds containing the same type of bond satisfying the necessary stability requirements exist in addition to the above-mentioned types of vr-organic nickel compounds, active catalyst components will also be found among these compounds.
• the advantage of the process according to the invention is that use is made of a soluble catalyst having such high activity that the reactions can take place at substantially lower temperature, pressure and catalyst concentration than those described as favourable in formerly known oligomerization processes of the Ziegler type.
• the composition of the reaction products differs at essential points from the above mentioned types of processes by the fact that there are formed dimerized and trimerized mono-olefines with very high content of betaand gamma-olefines.
• the formation of the active catalyst system is very simple. It occurs automatically at the mixing of the two types of catalyst components, advantageously in the form of solutions in an inert organic solvent, such as benzene, xylene, heptane or higher parafins, in argon or nitrogen atmosphere.
• the concentration of the main group metal compound, as well as the rela tive proportion of the two types of compound, can be varied within wide limits. It has been found favourable to the process to use main group metal concentrations within the range 0.001-0.100 mole/liter, and a nickelmain group metal molar ratio in the range 1:1-0.01:1.
• the process according to the invention can be performed at pressures from fractions of an atmosphere up to very large pressures, limited only by the apparatus construction. It is, however, advantageous, out of regard for temperature control, that the reactions take place at pressures not exceeding atm.
• the reducing effect which lies in the main group metal-carbon bonds BeC, AlC, Ga-C and In-C may lead to a reduction of the nickel compounds, if the temperature during the conversion is too high.
• the reaction temperature should therefore be kept below the temperature range in which a substantial part of the nickel compound in the course of the conversion is destroyed by reduction to preferably not exceeding 100 C.
• the highest reaction temperatures can be selected in the processes which make metallic nickel,.
• the process can be carried out either discontinuously, for example, by placing the catalyst components together with a solvent, if necessary, in a thermostat-regulated reaction vessel, passing the monomer or the monomer mixture for some time, e.g. 1-5 hours, into the catalyst mixture, and then extracting the reaction product by the usual working methods, or continuously, for example by passing the monomer or the monomer mixture through the catalyst mixture, with subsequent continuous isolation of the reaction product from the outflowing gas mixture. Unreacted monomer and solvent, if any, and catalyst are separated from the reaction product during the isolation of the latter and are suitably recirculated to the reaction vessel.
• solvent can be omitted with advantage.
• mixtures of their isomeric compounds may also be used as raw material for the processes, due to the isomerization activity of the catalyst systems.
• One or more of the above-mentioned types of nickel compounds are placed in a thermostat-regulated glass reaction flask, equipped with a magnetic stirrer, reflux condenser and dropping funnel with pressure-equalizing means. On the top of the reflux condenser there was a possibility of connection to vacuum, highly purified nitrogen and highly purified starting-monomer for the syntheses.
• the apparatus was evacuated for 1 hour, then filled with nitrogen. In the course of the nitrogen flushing the desired quantity of abs. solvent was added to the reaction flask.
• a main group metal compound of the above-mentioned type or mixtures of these are, if necessary diluted with solvent, then added to the dropping funnel in a nitrogen atmosphere.
• the whole apparatus is then carefully evacuated three times and after each time filled with the starting-monomer at atmospheric pressure.
• the two catalyst components each saturated with the starting-monomer, are mixed under agitation in the reaction flask.
• the inflow velocity of the starting-monomer required to maintain constant pressure in the reaction flask (1 atm.) was measured with a capillary flow meter as a function of reaction time.
• the bath temperature was kept constant within the limits i0.05 C. by means of a water-circulation thermostat. After a certain reaction time the conversion was stopped and the reaction mixture was gas-chromatographically analyzed.
• the reactions were carried out in a non-magnetic, acidresistant steel autoclave having a volume of 200 ml.
• the autoclave was connected with a glass container which could be evacuated.
• the connection between the two vessels could be closed by means of a high pressure valve.
• the autoclave and glass container were evacuated to less than 0.5 mm. Hg in 30 min.
• the valve between the two vessels was closed and the glass container filled with highly purified nitrogen.
• the catalyst components and the solvent were then poured into the glass container in a nitrogen atmosphere.
