    Abstract: The invention concerns a fatty alcohol obtainable by a method which consists in reducing the carbonyl function of a vegetable or animal oil, the method consisting in reacting said vegetable or animal oil with appropriate amounts of polymethylhydroxysiloxane (PMHS) in the presence of a catalytic system prepared from a metal salt or complex and a reduction agent, followed by hydrolysis of the resulting siloxane with a basic agent and separating and purifying the desired alcohol thus formed. Said alcohol can be used in a perfume composition, in particular as solubilizing agent.

    Abstract: A process for the enantioselective reduction of prochiral ketones to chiral alcohols by (a) the reaction of a prochiral ketone with a silane agent, which is present in a stoichiometric quantity, in the presence of a catalyst derived from a Zn, Co or Cd precursor compound and from a chiral amine, imine, alcohol or amino alcohol ligand; (b) the hydrolysis of the siloxane obtained using an appropriate agent; and (c) the separation and purification of the optically active alcohol formed. Polymethylhydrosiloxane (PMHS) is a preferred silane agent, zinc is a preferred metal, and the precursor compound is produced by reacting a salt or complex of the respective metal with the reducing agent. In another embodiment, an appropriate salt of the chosen metal is used directly in the reaction with the chiral ligand to produce the catalytic form after reaction with the ligand. The process enables high enantiomeric excesses (ee) to be obtained in chiral alcohols.

    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.
