Synthetic example

[0062] Synthetic example (long carbon chain trialkyl naphthalene sulfonic acid synthetic embodiment):

[0063] Taking the synthesis of alkyl dinonyl naphthalene sulfonic acid as a typical long carbon chain trialkyl naphthalene sulfonic acid as an example, under the protection of dry high-purity nitrogen, 5g (0.037mol) aluminum trichloride solid catalyst was added to 100g nitric acid Benzene solvent, stirred at 20°C for 0.5h, fully dissolved and added 99g (0.26mol) of dinonylnaphthalene (the substitution position of the nonyl group is not required), slowly added 0.275mol long Carbon chain brominated alkanes or alkenes (raw materials described in Table 1), then continue to stir the reaction for 1h, add 14.6g cold water to quench after the end of the reaction, then leave to separate layers, and the upper organic phase is washed with an equal volume of 10% NaOH aqueous solution Three times, and then washed with deionized water until neutral, and then the washed organic phase was d...

Embodiment 1

[0092] Taking trinonylnaphthalenesulfonic acid as a typical long carbon chain trialkylnaphthalenesulfonic acid as an example, add trinonylnaphthalenesulfonic acid to dinonylnaphthalenesulfonic acid / 4-pyridinecarboxylate isooctyl synergistic extractant, When its addition is 40% (mol percent) of the total amount of sulfonic acid groups in the organic phase, investigate the extraction effect of the simultaneous direct extraction of nickel and cobalt in the acidic polymetallic solution by the extraction temperature, the extraction clarification rate, the amount of solubilized water in the loaded organic phase and the effect of reverse micelle morphology.

[0093] Get the trinonylnaphthalenesulfonic acid synthesized in 10.2g synthetic examples (the product that 1-C case in table 1 obtains, wherein trinonylnaphthalenesulfonic acid 0.012mol, dinonylnaphthalenesulfonic acid 0.006mol), add 5.5g Dinonylnaphthalenesulfonic acid (0.012mol) and 14.1g isooctyl 4-pyridinecarboxylate (0.06mol...

Embodiment 2

[0102] Taking trinonylnaphthalenesulfonic acid as an example, add long carbon chain trialkylnaphthalenesulfonic acid to dinonylnaphthalenesulfonic acid / 4-pyridinecarboxylate isooctyl synergistic extractant, and its addition amount is the sulfonic acid in the organic phase When the total amount of groups is 40% (mole percent), the influence of concentration of extractant on simultaneous direct extraction of nickel and cobalt in acidic multi-metal solution, extraction clarification rate, loading organic phase solubilizing water and reverse micelle morphology was investigated.

[0103] Get the synthetic trinonylnaphthalenesulfonic acid (the product that the 1-C case in table 1 obtains in the 51g synthesis example, wherein trinonylnaphthalenesulfonic acid 0.06mol, dinonylnaphthalenesulfonic acid 0.03mol), add 27.5g dinonylnaphthalenesulfonic acid Nonyl naphthalene sulfonic acid (0.06mol) and 60.5g 4-pyridinecarboxylate (0.06mol), are configured into the mol ratio 1 of ester group i...

Abstract

In the field of non-ferrous metal hydrometallurgy, the present invention specifically provides an application method of trialkylnaphthalenesulfonic acid, which is added to dialkylnaphthalenesulfonic acid and pyridine carboxylate to speed up the extraction and phase separation; in addition, the present invention The invention also discloses a synergistic extractant containing the trialkylnaphthalene sulfonic acid, including trialkylnaphthalene sulfonic acid, dialkylnaphthalene sulfonic acid and pyridine carboxylate; this recipe also includes the synergistic extraction The preparation of reagents and the application in simultaneous direct extraction of nickel and cobalt from Ni2+, Co2+, Fe3+, Ca2+, Mg2+ and other multi-metal acidic solutions. In the present invention, adding long carbon chain trialkylnaphthalene sulfonic acid to the synergistic extractant containing dialkylnaphthalene sulfonic acid and pyridine carboxylate can significantly improve the extraction and phase separation speed of the extraction agent, so that the extraction clarification rate meets the mixing The requirements of the industrial design of the clarifier do not affect the extraction rate of nickel and cobalt directly extracted from multi-metal acidic solutions containing Ni2+, Co2+, Fe3+, Ca2+, Mg2+, etc. Remove the effect.

Description

technical field [0001] The invention belongs to the field of nonferrous metal hydrometallurgy, and in particular relates to an extractant for metal extraction. Background technique [0002] With the depletion of high-grade nickel sulfide ore resources, low-grade laterite nickel ore and secondary resources containing nickel and cobalt (such as spent nickel and cobalt catalysts containing iron, calcium and magnesium impurities, etc.) will become important resources of nickel and cobalt in the world. For the extraction of nickel and cobalt from low-grade lateritic nickel ores and secondary resources containing nickel and cobalt, the lengthy hydrometallurgical extraction process of "leaching-removing iron and aluminum-nickel-cobalt precipitation-acid leaching-nickel-cobalt separation" is usually adopted. The process of extracting nickel and cobalt has become an important method for short-process, clean and efficient extraction of nickel and cobalt from acid leaching solution, an...
