    摘要： A process that employs a heterogeneous catalyst comprising a zinc aluminate mixed oxide and having the following formula: ZnAl2O4, xZnO, yAl2O3 in which x and y each represent a number in the range 0 to 2, and in which the zinc aluminate is more particularly of the spinel type, makes it possible, by means of C1 to C5 monoalcohols, to: transesterify vegetable or animal oils having a natural free acidity, such as unrefined degummed rapeseed, soya, sunflower oils or exotic oils of the African oil, palm nut oil or coconut oil type, which are naturally rich in fatty acids; and simultaneously esterify their free acidity; so as to use phospholipid free and/or degummed unrefined acid oil with an acid number in the range 0.5 to 20, for example 1 to 15 and preferably 2 to 12, to produce esters, for example methyl esters, for use as fuels.

    摘要： A novel process is described for producing esters of linear monocarboxylic acids containing 6 to 26 carbon atoms, by reacting vegetable or animal oils, neutral or otherwise, with monoalcohols containing 1 to 18 carbon atoms in the presence of a catalyst selected from: mixtures of titanium oxide and alumina having formula: (TiOx)y(Al2O3)1-y where x has the value 1.5 to 2.2 and y, representing the weight ratio of the two oxides, has a value of 0.005 to 0.995; mixtures of zirconium oxide and alumina having formula: (ZrOx)y(Al2O3)1-y where x has the value 1.5 to 2.2 and y has a value of 0.005 to 0.995; and mixtures of antimony oxide and alumina having formula: (SbOx)y(Al2O3)1-y where x has the value 1.2 to 2.6 and y has a value of 0.005 to 0.995, in order to directly produce, in one or more steps, an ester for use as a fuel and a pure glycerin.

    摘要： Co dimerization is conducted of at least one monoolefin, for example a monoolefinic hydrocarbon such as ethylene, propylene or 1-butene, a halogenated monoolefin such as vinyl chloride, or an olefinic functional compound such as methyl acrylate, acrylonitrile, allyl acetate or vinyl acetate, with at least one polyolefin containing at least two conjugated or unconjugated ethylene bonds, for example a diene hydrocarbon such as 1,3-butadiene, piperylene, or isoprene or a polyolefin containing a carboxylic function, such as a fatty acid or a fatty acid ester having 14 to 24 carbon atoms in the fatty chain derived, for example, from a natural oil. The reaction is carried out in the presence of a catalytic system having general formula [RhX.sub.4 ][YR.sub.4 ] where X represents a halogen ion or a SO.sub.4.sup.--, SO.sub.3.sup.-, OH.sup.-, OR.sup.- or R.sup.- group, at least one X being a halogen ion, Y represents a nitrogen atom or a phosphorous atom, and R represents an alkyl, cycloalkyl, alkenyl, aryl, alkylaryl, polystyryl, alkyl polystyryl or acyl radical.
