Title:

METHOD AND DEVICE FOR DETERMINING ISOMER COMPOSITION IN ISOCYANATE MANUFACTURING PROCESS

Document Type and Number:

Japanese Patent JP2004347598

Kind Code:

A

Abstract:

To provide an improved method for determining the isomer composition of isocyanate isomer mixtures.

In the method for determining the isomer composition of isocyanate isomer mixtures, the actual isomer composition of the isocyanate isomer mixtures are determined, by recording the spectrum of the isocyanate isomer mixture (1) and by evaluating the spectrum using a chemometric calibration model (2).
