Process for producing oxygen-containing compounds containing at least one oxygen atom bonded to two distinct carbon atoms which are not bonded together and not including a multiple bond

A process for preparing an oxygen-containing compound containing at least one oxygen atom bonded to two distinct carbon atoms which are not bonded together and not comprising a multiple bond which is from the acetal group, said process comprising:

• a step a) for catalytic hydrofornylation of a feed comprising at least one olefin containing four to seven carbon atoms to at least one aldehyde,
• a step b) for hydrogenating said aldehyde to at least one corresponding alcohol carried out in the liquid phase in two successive steps, in a first step using a catalyst based on molybdenum disulphide on carbon and in a second step using a catalyst based on nickel on alumina, each of these steps being carried out at a temperature in the range of 100° C. to 300° C. and at a partial pressure of hydrogen in the range of 10 to 30 MPa, and
• a step c) for at least partial transformation of at least one alcohol obtained from step b) into a mixture of products comprising at least one oxygen-containing compound containing at least one oxygen atom bonded to two distinct carbon atoms which are not bonded together and not comprising a multiple bond in the presence of an H+ ion exchange resin at a temperature range of 70° C. to 100° C., and wherein transformation of the alcohol in step c) yields a mixture of products comprising an acetal having 11 to 17 carbon atoms, unconverted alcohol and water.
