Abstract

The invention belongs to the technical field of ion exchange resin, and relates to a preparation method of macropore strong acid type styrene series ion exchange resin. The preparation method of the macropore strong acid type styrene series ion exchange resin comprises the following steps: (1) preparation of a water phase: mixing softened water, industrial salt, methylene blue and a polyvinyl alcohol aqueous solution, stirring and heating for subsequent use; (2) preparation of an organic phase: after mixing styrene and the polystyrene resin, stirring, adding solid paraffin, heating and reacting, stirring and dissolving, sucking divinylbenzene, adding an initiator, and stirring to obtain the organic phase; (3) mixing the organic phase and the water phase at a mass ratio of 0.428-0.445: 1; carrying out heating reaction, and filtering out liquid; adding methylbenzene for washing; after the methylbenzene is filtered thoroughly, adding water, carrying out heating reaction, washing and carrying out hot-air drying; and adding sulfuric acid, carrying out heating reaction, cooling, and adding water for diluting to obtain the final product. The prepared resin is simple in process, is environmentally friendly and pollution-free, and is widely used for water treatment, the organic impurity removal rate reaches 99% or above, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of ion exchange resins, and in particular relates to a preparation method of macroporous strongly acidic styrene-based ion exchange resins. Background technique [0002] There are a wide variety of ion exchange resin products. According to the nature of the active groups it carries, it can be divided into strong acid cations, weak acid cations, strong base anions, weak base anions, chelating, amphoteric and redox resins; according to different functions and principles of action, it can be divided into water treatment Resins, adsorption resins and resin catalysts, among which water treatment resins have the most output; according to different pore types, they can be divided into gel type and macroporous type; [0003] Among them, strong-acid cation exchange resins have been widely used as catalysts in organic reactions such as esterification, hydrolysis, condensation, hydration, alkylation, and acylation in ...
