FIELD: physics, measurement.
SUBSTANCE: group of inventions is related to the field of isomer composition definition in mixture of isocyanate isomers and to control of installation for mixing and separation of isomers. Method for determination of isomer composition in mixture of isocynate isomers includes recording of infrared spectrum or spectrum of isomer mixture light combination scattering, introduction of spectrum data into chemometric calibrating model and spectrum calculation with the help of this model according to procedure of Partial Least Square. Invention also specifies method for control of installation that operates with isomers for preparation of isocyanates mixture of specified composition, and also device for preparation of specified mixture.
EFFECT: development of efficient method for definition of isomer composition in mixture of isocyanate isomers.
