Abstract

The invention provides macroporous adsorption resin which is prepared from the following raw materials: water, gelatin, styrene, divinylbenzene, white oil, an initiator, a pore-foaming agent, solventoil, 1,2-dichloroethane, zinc chloride and chloromethyl ether by the the following steps: carrying out white ball polymerization, white ball drying and screening, carrying out wax extraction, wax balldrying and screening, chlorination, chlorine ball drying and post-crosslinking reaction. The prepared resin is relatively large in specific surface area and porosity and has relatively good mechanical strength, high temperature resistance, simple preparation process and easy industrial production.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to a macroporous adsorption resin and a preparation method thereof. Background technique [0002] Adsorption resin refers to a class of high molecular polymers, which can be used to remove organic matter in wastewater, decolorize sugar solution, separate and refine natural products and biochemical products, etc. There are many kinds of adsorption resins, and changes in monomers and functional groups on monomers can endow resins with various special properties. Polymers such as polystyrene resin and polyacrylate resin are commonly used. Adsorbent resin is a resin adsorbent characterized by adsorption and has a porous three-dimensional structure. It is a newly developed porous resin in the field of polymers in recent years. It is made of monomers such as styrene and divinylbenzene in the presence of organic solvents such as toluene. Small circles like fish roe are prepa...
