Abstract: The present invention relates to a process for the production of olefinic compounds that can be used for the production of detergents, additives, lubricants and/or plastic materials, or components which can be used in the field of oil explorations and productions, and a hydrocarbon fuel or a fraction thereof, which comprises subjecting a mixture of glycerides having at least one unsaturated hydrocarbon chain, to metathesis reaction and, after separating the olefinic mixture obtained, effecting a hydrodeoxygenation and subsequently hydroisomerization process, so as to obtain the hydrocarbon fuel or a fraction thereof.

Abstract: Method for the separation of at least one isoprenic constituent from the resin of a plant of guayule and/or of the guayule type comprising the steps of: a) providing a defatted resin of guayule and/or of the guayule type; b) subjecting the defatted resin to partitioning of the liquid-liquid type with solvents that are immiscible in each other thus obtaining an apolar extract containing the isoprenic constituents guayulin A, guayulin B and argentatin B; and a polar extract containing the isoprene constituents argentatin A, argentatin C and argentatin D; and c) separating at least one isoprenic constituent from said polar extract and/or from the apolar extract thus obtained, wherein step c) comprises a step in which the polar extract is subjected to partitioning of the liquid-liquid type with solvents immiscible in each other and/or a step in which the apolar extract is subjected to partitioning of the solid-liquid type.

Abstract: The present invention relates to a process for the dehydration of at least one oxygenated compound, preferably selected from saturated alcohols, unsaturated alcohols, diols, ethers, in the presence of at least one dehydration catalyst selected from cerium oxide (CeO2), aluminium oxide (γ-Al2O3), aluminium silicate, silica-aluminas (SiO2—Al2O3), aluminas, zeolites, sulfonated resins, ion-exchange resins, metal oxides (for example, lanthanum oxide, zirconium oxide, tungsten oxide, thallium oxide, magnesium oxide, zinc oxide); of at least one basic agent selected from ammonia (NH3), or from inorganic or organic compounds containing nitrogen capable of developing ammonia (NH3) during said dehydration process; and, optionally, of silica (SiO2), or of at least one catalyst for the dissociation of ammonia (NH3) selected from catalysts comprising silica (SiO2), preferably of silica (SiO2).
