摘要： A method for the recovery of metals, generally heavy metals or chelatable metals such as zinc or copper from chloride solutions such as acid chloride etching solutions comprises extracting the metal with a mixed extracting agent of anion exchange/chelating, solvating/cation exchange or anion exchange/cation exchange character, separating the organic phase washing it with water, aqueous ammonia or aqueous ammoniacal ammonium sulphate, stripping the metal from the organic phase thereby obtained by contacting it with sulphuric acid and returning the organic phase to the extraction stage for reuse after regenerating it.

摘要： Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyrimidine, pyrazine or pyridazine derivitives bearing the substituent-(C=O.X) n where X is the group-OR, or-NR 2 R 3 and n ist 1, 2 or 3. R, is a hydrocarbyl group containing from 1 to 36 carbon atoms and R 2 and R 2 together contain from 1 to 36 carbon atoms. The molecule as a whole contains from 5 to 36 alkyl carbon atoms and may carry further optional substituents. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containg ores.

摘要： Provided is a method for producing separated substances, particularly metal compounds, the dopant element amounts of which have been controlled by the use of an apparatus that processes fluid between the processing surfaces of a processing member that can be made to approach/separate and which rotate relative to each other. Using the apparatus that processes fluid between the processing surfaces 1 and 2 of the processing member that can be made to approach/separate and which rotate relative to each other, the substance to be separated is separated by mixing a raw material solution, wherein the substance to be separated is solubilized in a solvent, with the solvent for separation and with the dopant element or dopant element-containing substance solubilized in at least one solvent selected from the solvent of said raw material solution, said solvent for separation or a solvent other than that of said raw material solution or said solution for separation. Separated substances with controlled dopant element amounts are obtained by controlling the solubility of the dopant element or dopant element-containing substance in the solvent for separation.

摘要： In a method of performing a chemical reaction using a Lewis acid, after the reaction is complete, the Lewis acid is extracted from the reaction product in the form of an aqueous solution, followed by drying of the aqueous solution of the Lewis acid. The dried Lewis acid can be reused in a further similar reaction. The method can be repeated several times, using the same batch of Lewis acid, without the activity and specificity of the Lewis acid being significantly affected. The invention has been used to good effect in the ene reaction of isopulegol from citronellal, the Diels-Alder reaction of myrcene and 3-methyl-3-penten-2-one and the rearrangement reaction of α-pinene oxide to campholenic aldehyde using zinc bromide as a Lewis acid catalyst. The invention can thus provide an environmentally acceptable and efficient method for using Lewis acids in industrial processes.

摘要： The invention relates to a method for neutralizing a sulfuric acid solution containing predominantly Zn ion. In the method of the invention at least one compound selected from chlorine-containing compounds of Na ion, K ion, Mg ion, Ca ion, and NH₄ ion in an amount at least chemically equivalent to SO₄ ion contained in the solution is added to the sulfuric acid solution. Then the sulfuric acid solution is brought into contact with an organic solvent composed of one or more species selected from oxygen-containing organic solvents and alkylamine organic solvents to extract Zn ion from the sulfuric acid solution as a chloride complex to the organic solvent. The sulfuric acid solution after extraction of Zn ion may be further treated by addition of an oxidizing agent or by an electrochemical means to convert Fe²⁺ into Fe³⁺ ion and brought into contact with a second organic solvent (B) composed of one or more species selected from oxygen-containing organic solvents and alkylamine organic solvents. In that manner Fe ion is extracted from the sulfuric acid solution as a second chloride complex to the second organic solvent (B).
