Catalysis of Isomerization Reactions by Ionic Resins


Alfa Chemistry can customize ionic resin catalysts for isomerization reactions. In addition to customized services, existing resin catalysts can also be modified. We have advanced synthesis laboratories and manufacturing plants, which can provide products ranging from milligrams to hundreds of kilograms. Our ionic resin catalyst will undergo various standardized tests before delivery, and the quality is guaranteed.


Ionic resin catalysts are also widely used in isomerization reactions. As early as 1986, ionic resins were used to catalyze the isomerization of olefins. Terpene alcohol is one of the important monocyclic alcohols. It can be used as a perfume and textile wetting agent. Because of its bactericidal activity, it can also be used as a disinfectant. Ion exchange resins can catalyze the hydration and isomerization of biomass turpentine, and exhibit 97% conversion and 57% selectivity when preparing terpene alcohols. In addition, it has super recyclability, even after multiple runs, it still maintains good activity.

Camphene is an intermediate compound of commercial chemicals such as isobornyl, isobornyl acetate and camphor. The traditional production process of camphene mainly uses acidic TiO2 catalyst to isomerize α-pinene. The use of the catalyst has problems such as preparation, reproducibility, and relatively long time to recover the catalyst from the product after α-pinene isomerization. Using ion exchange resin to replace TiO2, it is found that the similar catalytic effect can be achieved by adjusting the temperature and the ratio of α-pinene/catalyst, and the problem of catalyst recovery can also be solved.(Chimal Valencia O, et al.,2004)
