Abstract

A supermacroporous strong base anion exchange resin with quaternary amine group consists of the following materials in part by weight: aqueous phase: 1000 to 1500 parts of pure water, 5 to 8 parts of dispersing agent and 50 to 70 parts of dispersing auxiliary; and oil phase: 50 to 75 parts of methyl acrylate, 15 to 25 parts of divinylbenzene, 10 to 25 parts of third monomer, 70 to 100 parts of novel porogen and 0.5 to 1 part of initiator. A preparation process for the supermacroporous strong base anion exchange resin with quaternary amine group includes the following steps: (a) suspension polymerization; (b) amidation; (c) quaternization. The invention has the advantages that: the selectivity of the prepared resin on biochemical substances is enhanced; the reaction time is shortened, and the efficiency is increased; the prepared resin has even supermacropores, and compared with the conventional resin, the resin has the advantages of large exchange capacity and high mechanical strength; the product reaction conversion rate is high, the physical and chemical structures are stable, and the resin cannot be easily degraded.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a strong base anion exchange resin with a quaternary ammonium group and a strong base anion exchange resin with a quaternary ammonium group and a preparation process thereof. Background technique [0002] Acrylic ion exchange resin has the advantages of high exchange capacity, good anti-organic pollution performance, etc. It has a wide range of uses, and its output is second only to styrene resin. However, using the traditional process, because the third monomer and new porogen are not added, and its amination process is usually carried out at normal temperature and pressure, the inner pores of this type of resin are smaller, and for the larger molecular weight It is difficult for the substance to enter the interior of the resin, so its selectivity is poor, and the physical and chemical structure stability is poor. [0003] So far, the preparation method of...
