A new hight performance liquid chromatography(HPLC) method was established for the determina-tion of diphenylmethane 4,4'-diisocyanate(MDI) and the middle of produce was derived by ethanol without water. The chromatographic conditions:the separation was performed on a Agilent Eclipse XDB-C 18 column with Water-methyl alcohol (40∶60,V/V)as the mobile phase at a flow rate of 1.0mL·min-1. The detection wavelength was set at 245 nm, the column temperature was 30℃. Under the optimized condition ,there was good linear relationship be-tween the mass concentration and the peak area of MDI and the middle of produce with the correlation coefficient r>0.999. The method is good reproducibility, hight sensitivity, simple and rapid.
