    摘要： A process is disclosed for chlorinating, brominating and/or iodinating an organic substrate containing both a single acidic hydrogen atom and at least one electron withdrawing group attached to the same carbon atom. The process replaces the single acidic hydrogen with chlorine, bromine and/or iodine and involves reacting the substrate in solution with a halogenating agent (e.g., a perhalomethane wherein the halogen substituents are I, Br and/or Cl, a trihaloacetic acid ester wherein the halogen substituents are Br and/or Cl, or a perfluoroalkyl halide wherein the halide is I, Br and/or Cl) in the presence of (i) a phase transfer catalyst of the formula R.sup.1 R.sup.2 R.sup.3 R.sup.4 LJ where L is selected from the group consisting of phosphorus and nitrogen, where J is an inorganic anion other than fluoride, and where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently chosen from the froup consisting of hydrocarbyl radicals containing from 1 to about 20 carbon atoms and (ii) a mild inorganic base which is insoluble in the reaction medium.

    摘要： An improved process for the manufacture of aromatic dicarboxylic acids and derivatives thereof is described. The process is based on the reaction of a corresponding aromatic hydrocarbon in a liquid phase oxidation with an oxygen-containing gas in the presence of a phase-transfer catalyst (a) a transition metal salt (b) and traces of a polar solvent, such as water, the molar ratio between (a) and (b) being in the range of between 0.25:1 to 1.5:1. The phase-transfer catalyst is selected from the quaternary ammonium and phosphonium salts having a total carbon atoms in the range of 17 to 58, the anion bound thereto being selected from Br.sup.-, F.sup.-, Cl.sup.-, OH.sup.-, CH.sub.3 COO.sup.- and HSO.sub.4. Among the aromatic dicarboxylic acids and derivatives thereof the following are mentioned: terephthalic acid; isophthalic acid and methyl terephthalate. The process is characterized by the very high conversion of the respective aromatic hydrocarbon reaching even 100%.

    摘要： A wet scrubber for absorbing elemental heavy metal from a gas stream, a liquor for a wet scrubber, and a power-plant comprising a wet scrubber are described. The wet scrubber includes a vessel having a gas inlet and outlet. In the vessel is a liquor including a oxidizer capable of oxidizing the elemental heavy metal and an ionic liquid. The liquor is substantially free of any ligand capable of bonding an ion of the heavy metal.
