Oil-soluble sulfide remover, preparation method and application

According to the oil-soluble sulfide remover, the preparation method and the application, organic sulfonic acid and tetrakis (hydroxymethyl) phosphonium inorganic acid salt are used as main raw materials, inorganic acid is replaced through the reaction of the organic sulfonic acid and the tetrakis (hydroxymethyl) phosphonium inorganic acid salt in a xylene solvent under the action of a phase transfer catalyst tetrabutylammonium chloride at a certain temperature, and the oil-soluble sulfide remover is obtained. And increasing oleophylic groups in molecules to prepare the oil-soluble sulfide remover tetrakis (hydroxymethyl) phosphine organic sulfonate xylene solution. According to the oil-soluble sulfide remover, due to the addition of the organic sulfonic acid oleophylic group, the oil phase permeability, dispersity and interfacial activity of the oil-soluble sulfide remover are remarkably enhanced on the premise of ensuring the complexing ability to ferrous sulfide. Ferrous sulfide in an oil phase, aged oil a
