Abstract
Publisher Summary Ion exchange resins are synthetic polymer based on crosslinked polystyrene into which functional ion exchange groups are introduced. Resins that utilize quaternary ammonium as the ion exchanging group are known as strongly basic anion exchange resins. Conventional strong basic anion exchange resins have been widely used in various fields. These types of resins have defects on their chemical stability because of the relative instabilities of the quaternary ammonium functionality in the benzyl position. They are not suitable for applications at high temperature. From this point of view, the novel resin with a different chemical structure has been developed. Based on the improved stabilities of this resin, a number of advantageous operations at elevated temperature are suggested. This chapter discusses the characteristics of the novel resin and its usage as a solid base catalyst in catalytic reactions. The introduction of an alkyl or ether spacer between the benzene ring and the quaternary nitrogen in anion exchangers effects an increase in the chemical and thermal stability of the functional group.
