摘要

Polyurethanes are produced by reacting diisocyanates with polyols and other chemicals.rnApproximately 90% of phosgene production is used in the manufacture of isocyanates forrnpolyurethane resins. Nearly all phosgene is used at the point of manufacture due to its reactivityrnand toxicity. The benefits of an on-line filter photometer to measure different points of thisrnmanufacturing process will be discussed. The continuous measurements provided by filterrnphotometers allow for a fast response to process changes for better control, safety, and processrnoptimization. Some of the applications that will be discussed will be the production of phosgenernfrom carbon monoxide and chlorine and the production of isocyanate resin from an amine andrnphosgene. These applications span the IR, NIR, and UV regions in both liquid and vapor phasesrnand demonstrate the photometer’s capabilities and benefits in optimizing the polyurethanernmanufacturing process.
