    摘要: A photodegradative process is described for the purification of water contaminated by ether-based compounds, especially methylterbutyl ether (MTBE) or its analogous products, which comprises the following steps: (a) treatment of the contaminated water with an inorganic acid up to a pH ranging from 4.0 to 4.5 with the elimination of the carbon dioxide thus formed; (b) dispersion in the water of solid particles of a metal oxide of the semiconductor type or dissolution of a stream consisting of ozone in pure oxygen or air; (c) irradiation of the dispersion or solution obtained in step (b) with ultraviolet light to degrade the ether-based contaminants.

    摘要: A method is disclosed for preparing functionalized adenine derivatives, said method comprising the step of reacting a compound which contains an adenine nucleus which has been halogen substituted in the 8-position, with a compound having the general formula M.sup.+- S--(CH.sub.2).sub.n --COO.sup.- M.sup.+ wherein M.sup.+ is the ion of an alkali metal and n is an integer, the reaction being carried out in a polar aprotic solvent. Procedures for preparing macromolecularized adenine compounds are also indicated by reacting a functionalized adenine derivative with a polymer which has at least one primary or secondary aminic group in its structure.

    摘要: A hybrid fuel composition in the form of a stable water-in-oil microemulsion comprises a liquid hydrocarbon fuel, water, a glycolipid surfactant and a vicinal aliphatic diol co-surfactant. The hydrocarbon fuel can be a liquid fuel for autotraction such as gasoline or diesel fuel, or a liquid hydrocarbon fuel for domestic or industrial heating, such as gas oil, naphtha, kerosene and fuel oils in general.

    摘要: Oil drill cuttings, containing an oil-based mud, may be treated by mixing the cuttings with an organic solvent. The oil drill cuttings are then separated from the organic solvent and extracted oil. The organic solvent is then separated from the oil, and mixed with the extracted oil drill cuttings to extract additional oil therefrom. The oil drill cuttings are again separated from the organic solvent and oil, the oil separated from the solvent, and recombined with the oil from the first extraction step. The oil base and other mud components are recycled, depending on the treatment procedure, for subsequent use in drilling.
