Abstract: The invention relates to a process for the preparation of 1-(1,3-benzodioxol-5-yl)-1-propanone comprising the step of reacting 3,4-dimethylendioxybenzene with propionic anhydride in the presence of a bulk or supported catalyst, being said catalyst selected from the group of a sulphonated cross-linked divinylbenzene resin, a sulphonated cross-linked divinylbenzene resin partially exchanged with iron, zinc or gallium, a perfluorinated sulphonic resin, and a perfluorinated sulphonic resin partially exchanged with iron, zinc or gallium, wherein said catalyst has an average particle size from 1 ?m to 300 ?m, preferably from 1 ?m to 180 ?m, more preferably from 1 ?m to 100 ?m as measured with DLS (Dynamic light scattering) or a granulometer. The process is advantageously carried out at stoichiometric ratio between the reagents and with a continuous process.

Abstract: A process for obtaining higher aliphatic alcohols starting from aliphatic primary alcohols by condensation reactions is disclosed. Specifically, the process comprises a step in which an aliphatic primary alcohol is contacted in a homogeneous phase with a catalyst mixture comprising a transition metal, a base and an additive; specifically, this additive can be selected from the classes of compounds of the isoquinolines N-oxide, quinolines N-oxide, pyridines N-oxide, benzoquinones, naphthoquinones, or TEMPO. In particular, the process can be carried out by contacting said aliphatic primary alcohol with a catalyst of a recycled transition metal, with a freshly added base and with a recycled additive of the aforementioned type.
