Problems solved by technology

[0002] At present, in the field of chemical production, other substances that can be used as collectors and metal extractants include cationic cetyl hydropyridine, anionic oleic acid soap, nonionic acetonitrile, etc., but the above substances are used as collectors. The reaction speed of the collector and the metal extractant and the mineral is slow, and it needs stirring assistance. The flotation time is long, which affects the efficiency, and the separation effect is sometimes not very ideal. Production
At present, the ideal collector and metal extractant is trioctylmethylammonium chloride. Due to technological reasons, the production capacity of trioctylmethylammonium chloride is limited and cannot meet the demand.

Abstract

The invention discloses a technique for producing methyl trioctyl ammonium chloride, which comprises the steps: trioctylphosphine ammonium and methyl chloride react under the condition of catalyst existence to generate the methyl trioctyl ammonium chloride, and the methyl trioctyl ammonium chloride can be rapidly generated in the reaction. In addition, according to the characteristics of cation and surface activity which are specially possessed by the self of the methyl trioctyl ammonium chloride, the invention discloses the application of taking the methyl trioctyl ammonium chloride as collecting agent and metal extracting agent in raw mineral material selection, and the application proves that the methyl trioctyl ammonium chloride has the characteristics of higher solubility in organic solvent and water, stronger selectivity, insensitivity for alkaline medium, excellent stability, erosion resistance and no toxicity.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a production process of trioctylmethyl ammonium chloride. Background technique [0002] At present, in the field of chemical production, other substances that can be used as collectors and metal extractants include cationic cetyl hydropyridine, anionic oleic acid soap, nonionic acetonitrile, etc., but the above substances are used as collectors. The reaction speed of the collector and the metal extractant and the mineral is slow, and it needs stirring assistance. The flotation time is long, which affects the efficiency, and the separation effect is sometimes not very ideal. Production. At present, the ideal collector and metal extractant is trioctylmethylammonium chloride. Due to technical reasons, the production capacity of trioctylmethylammonium chloride is limited and cannot meet the demand. Contents of the invention [0003] The invention provides a kind of trioctylmethyl...
