ExxonMobil to set off with the production of ultra-pure isopropyl alcohol at its Baton Rouge plant by 2027

ExxonMobil will begin producing 99.999% ultra-pure isopropyl alcohol (IPA) at its Baton Rouge facility by 2027 to meet the semiconductor industry’s stringent requirements. As chip manufacturing advances to 2-nanometer nodes, even microscopic impurities can disrupt production, making high-purity IPA essential for wafer cleaning and drying processes. The expansion reinforces domestic supply chains at a time when U.S. semiconductor production is growing under initiatives like the CHIPS Act.

The Baton Rouge complex, already the world’s largest IPA plant, leverages ExxonMobil’s century of chemical expertise to deliver this critical material. Unlike standard 99.9% IPA used in consumer products, the new ultra-pure grade ensures defect-free chip fabrication, supporting next-generation technologies. This move positions ExxonMobil as a key supplier in the semiconductor ecosystem while reducing reliance on foreign sources for advanced manufacturing inputs.
