    摘要： A process for hydroformylating olefinically unsaturated compounds by means of a cobalt-based catalyst is carried out in a non-aqueous ionic liquid which is a liquid at a temperature below 90° C. and comprises at least one ammonium and/or phosphonium and/or sulfonium cation Q+ and at least one anion A−; catalyst recycling is improved by using a ligand selected from the group consisting of Lewis bases and employing a depressurization step between the pressurized reaction step and the step for separating the phases by decanting. At the end of said depressurization step, the organic phase is separated in the decanting step and the non-aqueous ionic liquid containing the catalyst can be re-used.

    摘要： In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-iacid or diester) and to recycle the ethylene employed.
