Phenol is a key chemical intermediate used to manufacture polymers, synthetic fibers, resins, detergents, herbicides, and pharmaceuticals. Most phenol production relies on the cumene hydroperoxide route, in which acid cleavage generates phenol and acetone. This Process Application Note describes the online potentiometric titration of sulfuric acid using the 2060 TI EX Proof Process Analyzer to maintain tight process control, enhance phenol quality, and reduce chemical consumption.
Stearic acid and stearate derivatives are produced through multistep processing and require monitoring of key quality attributes, including iodine value, acid value, moisture, ash content, melting point, and granulometry. This study demonstrates that near-infrared (NIR) spectroscopy with the OMNIS NIR Analyzer enables rapid, nondestructive quantitative analysis of these parameters for both in-process and final-product samples.
Vinylene carbonate is a widely used lithium-ion battery electrolyte additive that requires strict moisture control to maintain battery performance and lifetime. Accurate moisture quantification was historically limited by side reactions, complicating the analysis. The introduction of alcohol-free coulometric Karl Fischer reagents now enables precise, reproducible moisture determination, facilitating more reliable control of additive and electrolyte quality during manufacturing.
PEDOT:PSS is a tunable, conductive coating whose properties depend on parameters such as counter-ion selection, secondary doping, and polymerization conditions. This Application Note demonstrates the combined use of EQCM-D, Raman spectroscopy, and electrochemical methods to monitor film growth, correlating frequency and dissipation changes across harmonics with in situ spectroscopic and electrochemical signals. The introduced probe-based EQCM-D platform enables simultaneous Raman acquisition, providing a powerful tool to design and optimize PEDOT:PSS coatings.
Control of NCO content in isocyanates is essential for polyurethane production. However, wet chemistry methods are slow, hazardous, and preparation intensive. Near-infrared spectroscopy (NIRS) offers a rapid, reagent-free alternative, determining NCO content in seconds without sample preparation. This makes NIRS a practical and environmentally compliant solution for routine quality control of isocyanate raw materials.
