Abstract:
An analytical method using gas chromatography-mass spectrometry (GC-MS) with headspace extraction has been developed to detect and quantify organic impurities in hydrochloric acid (HCl), a by-product of MDI synthesis. The method has identified twenty compounds with high precision (R² > 0.99) and limits of detection below 1 ppm. When applied to real samples, it demonstrates effectiveness for industrial quality control—particularly at the Covestro plant in Tarragona—thereby helping to ensure the purity and safety of HCl for food and industrial applications.
