Application of Ion Exchange Resin in Chemical Industry

  • 2022-11-10
In organic chemistry, acids and bases are often used as metal catalysts for esterification, hydrolysis, transesterification, hydration and other reactions. The above reactions can also be carried out by using ion exchange resin to replace strong oxidant and alkali, with more advantages. For example, the resin can be used continuously, the product can be separated easily, the tubular reactor will not be corroded, will not pollute the environment, and the reaction is easy to control.

Methyl tert butyl ether (MTBE) is prepared by reaction of isobutene and ethanol with macroporous strong acid ion exchange resin as catalyst, replacing the original tetraethyl lead which can cause environmental pollution.

In industrial separation and purification applications, synergy is the goal of application development. At present, in some units, ion exchange resin has been used together with active carbon to remove non-polar organic substances, such as perchloroethane, and ion exchange resin is used to remove polar pollutants, such as permanganate.
