Zusammenfassung: | PURPOSE: A measuring method of composition of isomer in manufacturing isocyanate and a device thereof are provided to increase the yield rate by measuring the spectrum of isomer compound and detecting the density of the isomer compound. CONSTITUTION: An isomer compound is manufactured(100), and an isomer mixture(G1) is separated from the raw isomer compound by distilling or crystallizing(102). The index is initialized(104), and the spectrum of the isomer mixture is measured at the outlet of the isomer manufacturing system. The NIR spectrum is analyzed by using the compensation model(108). The difference between the predetermined isomer compound and the actual isomer compound is measured(112), and the isomer manufacturing system is adjusted based on the difference value(114). The index is increased(116), and the next spectrum is measured. |
