Olefines are prepared by the catalytic dehydrochlorination of chlorinated paraffins having 5 or more carbon atoms by fractional distillation over metals or metal alloys of Groups Ib, IIa, IIb. IIIa, Va, VIa, VIIa and VIII of the Mendeleef Periodic Table, singly or in admixture, at temperatures of 150 DEG to 500 DEG C., condensation of the olefines formed at their boiling points corresponding to the reaction conditions from the vapours leaving the reaction, and withdrawal of the olefines from the condenser in boiling condition. The chlorinated paraffin feed may be derived from normal- or branched-paraffins, cycloparaffins or aromatics which bear normal- or iso-paraffinic or cycloparaffinic side chains and may be a mixture of the chlorinated paraffins together with the paraffins from which they are derived.ALSO:Primary alcohols are produced by the reaction, in conventional manner, of an olefine with carbon monoxide and hydrogen in the presence of a cobalt compound, said olefine having been obtained from the catalytic dehydrochlorination of chlorinated paraffins having 5 or more carbon atoms by fractional distillation over metals or metal alloys of groups Ib, IIa, IIb, IIIa, Va, VIa, VIIa and VIII of the Mendeleef Periodic system, singly or in admixture, at temperatures of 150 DEG to 500 DEG C., the olefines formed being condensed in a condenser at their boiling points corresponding to the reaction conditions from the vapours leaving the reaction and then withdrawn from the condenser in boiling condition. The chlorinated paraffin feed may be derived from normal or branched paraffins, cycloparaffins or aromatics which bear normal- or iso-paraffinic or cycloparaffinic side chains and may be a mixture of the chlorinated paraffins together with the paraffins from which they are derived. |
