What are the Industrial Applications of Magnesium Ion in Catalysis?
In industry, magnesium ion is employed in various catalytic processes, particularly in the synthesis of chemicals and materials. It is used in the production of [polyethylene terephthalate (PET)](https://en.wikipedia.org/wiki/Polyethylene_terephthalate), a common plastic, where Mg2+ acts as a catalyst in the esterification and polycondensation reactions. Additionally, Mg2+ is involved in the production of biofuels, where it catalyzes transesterification reactions to convert oils into biodiesel.
