    Abstract: The invention concerns peroxide complexes of metals complying with the general formula LnMXpY, wherein M is a metal selected from groups VIII, IB and VIIB, particularly cobalt, X is an anionic group, for example carboxylate, R is an alkyl, cycloalkyl or arylalkyl group, n=1 or 2, p=0 or 1 and n+p=2.L is a tridentated ligand from the group of 1,3 bis (2-pyridylimino) isoindolines.These complexes are obtained by reaction of a hydroperoxide ROOH with a complex of formula LnMXp. They can be used in oxidizing hydrocarbons to a mixture of alcohols and ketones, either as reactants or as catalysts.They are particularly useful to prepare tert-butanol by oxidation of isobutane in liquid phase, by means of an oxygen-containing gas such as air.

    Abstract: Process for producing olefins from natural gas, the natural gas (2) is mainly fractionated (1) into methane (3) and higher hydrocarbons (4), the latter being then mainly fractionated (17, 20) into propane (9) and ethane (7). The methane (3), admixed with oxygen (6), passes through an oxidation reactor (5), receives the ethane (7) and the obtained mixture passes through a pyrolysis reactor (8). The effluent coming out of reactor (8) receives the propane (9) and the obtained mixture passes through a pyrolysis reactor (10). A hydrocarbon flow comprising olefins (12), more particularly ethylene and propene, is recovered.
