  Heterogeneous catalysis in ionic liquids: The heck reaction of bromobenzene with styrene over palladium supported on mesoporous carbon

  摘要：

  Tributylhexylammonium bistriflamide [(C4H9)(C6H13)N][(CF3SO2)(2)N], an ionic liquid, was used as a solvent for the Heck reaction of bromobenzene with styrene in the presence of Pd deposited onto a mesoporous carbon support. It was found that dibutylamine used as a basic reagent to scavenge hydrogen bromide results in higher conversions of the reactants and higher yields of stilbene than sodium acetate. It was shown that the IL is fully recoverable after use in the catalytic reaction.

  The heterogeneous catalytic heck reaction in an ionic liquid

  摘要：

  The C-C cross coupling reaction between bromobenzene and styrene in the presence of Pd deposited on mesoporous acetylene soot (Pd/C) occurred in a tetraalkylammonium ionic liquid (IL) as a truly heterogeneous catalytic process. The active palladium form was not transferred into the reaction solution. Deposited palladium activation was observed when the Pd/C catalyst was preliminarily heated in the IL in the presence of dibutylamine as a base.

  The invention relates to a method of treating a liquid hydrocarbon (e.g. heavy oil, bitumen, etc.) containing naphthenic acids or other corrosive acids in order to partially or fully convert such acids into non-corrosive compounds. The method comprises adding an alkylating agent to the hydrocarbon, bringing the hydrocarbon into contact with an aqueous liquid containing an alkaline compound and a phase transfer catalyst to form an immiscible two-phase system, maintaining the contact to allow conversion of the naphthenic acids to non-corrosive oil-soluble esters, and separating the aqueous phase from the liquid hydrocarbon. Naphthenic acids are highly corrosive to plant and equipment and the method enables them to be converted to non-corrosive compounds in an economic manner.
• Process for Removing Sulphur From Liquid Hydrocarbons

  A process for the deep desulfurisation of hydrocarbons (HC), in particular Natural Gas Condensate (NGC), and HC comprising diesel, pre-extracted diesel and naphtha, is described which is capable of reducing the sulfur content of these HC from 500 to 30 ppm. The process comprises contacting the hydrocarbon material with an oxidant selected from organic peroxy acids, organic peroxides, inorganic peroxides and mixtures thereof, in at least a stochiometric amount sufficient to oxidise a sulfur compound to a sulfone compound; contacting the hydrocarbon material with an aqueous extractant to allow at least a portion of the oxidised sulfur compounds to be extracted into the aqueous extractant, and separating the hydrocarbon material from the aqueous extractant to give a hydrocarbon material of reduced sulfur content. Optionally, the process may include a second and subsequent extractions with the aqueous extractant to further reduce sulfur content. A final extraction with an IL may be conducted. The invention also provides for substitution of the aqueous extractant with an IL in one or more of the other extraction steps. The extractants and by products generated during f01 oxidation can be recovered by simple distillation techniques.
