    摘要： A method is provided for separating the impurities zinc, iron, calcium, copper and/or manganese from an aqueous solution that contains cobalt and nickel. The solution is brought into a mixing contact with an extraction solution, which is pre-loaded with cobalt and nickel ions, whereby the cobalt and nickel in the extraction solution are replaced with the impurity metals, and the aqueous solution is cleaned from impurities after this phase. This purified aqueous solution, raffinate, can be used to pre-charge the extraction solution so that a minor part of the raffinate is contacted with a pre-neutralized extraction solution, whereby the cobalt and nickel replace the alkali metal, alkali earth metal or ammonium ion that is used in the pre-neutralization.

    摘要： Lubricating oils consist of (i) silanes of the general formula wherein Z is hydrogen or a saturated or unsaturated monovalent hydrocarbon radical preferably having 1 to 18 carbon atoms, R is a monovalent hydrocarbon radical free from aliphatic unsaturation, n is 1 to 20, a is 1 or 2; b is 0, 1 or 2 and (a+b) is 1, 2 or 3; and (ii) siloxanes containing at least one group represented by the formula wherein Z, n, a, b, and (a+b) have the above meaning and R1 is R or a group OR.ALSO:The invention comprises (1) silanes of formula wherein Z is hydrogen or a saturated or unsaturated monovalent hydrocarbon radical preferably containing 1 to 18 carbon atoms, R is a monovalent hydrocarbon radical free from aliphatic unsaturation, a is 1 or 2, b is 0, 1 or 2 and (a+b) is 1, 2 or 3, and (2) siloxanes containing at least one unit represented by the formula wherein n, Z, a, b and (a+b) have the above meanings and R1 is equal to R or is a hydrocarbonoxy radical OR. The siloxanes can have linear, cyclic or branched structures and may form copolymers with at least one group wherein R1 is as above and c may be 0, 1, 2 or 3. They are prepared by hydrogenating the corresponding cyanophenylalkyl silicon compound and the primary amine formed may be converted to secondary or tertiary amines using alkyl halides or dialkyl sulphates. The hydrogenation is preferably conducted under a hydrogen pressure of 100 to 133 atmos. and at temperatures of 80 DEG to 140 DEG C. Catalysts may be used, e.g. platinum and palladium which may be supported on the gamma-allotrope of alumina or charcoal and other catalysts used include nickel cobalt and cyclopentadienyl metal compounds. Suitable solvents include alcohols and hydrocarbons. The siloxanes may also be prepared by hydrolysis of the corresponding silane which may also be cohydrolysed with groups. The examples describe the preparation of beta-(p-aminomethylphenyl)-ethyltriethoxysilane from the corresponding cyanophenylsilane and its subsequent hydrolysis and condensation to form a resin composed of the groups Uses: Corrosion inhibitors, lubricating oils, sequestering agents and coatings for metals. The starting materials are prepared by reacting an alkali metal cyanide with bromophenylalkylhydrocarbonoxysilane in a highly polar organic liquid, e.g. diethylformamide, in presence of cuprous cyanide and copper at 25-250 DEG C. Hydrolysis produces the corresponding siloxane starting materials.

    摘要： The invention relates to a method for separating the impurities zinc, iron, calcium, copper and/or manganese from aqueous solutions that contain cobalt and/or nickel. An aqueous solution (1) containing metallic salts is brought into a mixing contact with an extraction solution (2), which is pre-loaded with cobalt and/or nickel ions, whereby the cobalt and/or nickel in the extraction solution are replaced with the impurity metals, and the aqueous solution is cleaned from impurities after this phase. This purified aqueous solution, raffinate (3), can be used to pre-charge the extraction solution with cobalt and/or nickel ions, so that a minor part (5) of the raffinate is contacted with a pre-neutralized extraction solution (6), whereby the cobalt and/or nickel replace the alkali metal, alkali earth metal or ammonium ion that is used in the pre-neutralization. After this pre-charging stage, the aqueous solution that contains said alkali metal, alkali earth metal and/or ammonium ion, but no cobalt and/or nickel, is conveyed as reject (7) out of the process. After the extraction stage, the extraction solution (8) can be washed at a separate washing stage with washing water (9) that contains impurity metal chlorides. In that case, the cobalt and/or nickel ions remaining in the extraction solution are replaced with the impurity ions and they transfer to the chloride-containing aqueous solution. This washing water (11) can be conveyed to the pre-charging stage mentioned above, whereby the chloride ions that come along are removed to the reject. After the washing stage, the impurities can be back-extracted into the aqueous solution by the aqueous solution (13) of hydrochloric acid.
