Verfahren zur Bestimmung der Isomerenzusammensetzung bei Isocyanat-Herstellprozessen |
摘要 |
Determining the isomer composition of an isocyanate isomer mixture (A) involves recording the spectrum of the mixture and inputting it to a chemometric calibration model. Independent claims are also included for; (1) A method for controlling a unit that produces the mixture with a standardized isomer composition by applying the new method, detecting any difference between the actual and standard isomer compositions, and controlling one or more process parameters, according to the detected difference; and (2) A unit for producing the mixture with a standard isomer composition that includes a device for recording spectra and a chemometric model for determining the actual isomer composition, device for calculating any difference between actual and standard compositions, and system for regulating process parameters. |
