2-nitro-FLUOREN-9-ONE


2- method for determination of nitro fluorenone content by a reversed-phase high-performance liquid chromatography. The liquid chromatography conditions are: EliteHypersil ODS2C18 chromatography column (4.6mm x 250mmi.d., 5 mu m), methanol tetrahydrofuran water as the mobile phase (volume ratio of 65: 15: 35). The flow rate of 1.0mL/min, the detection wavelength of 254nm, the column temperature under 25 DEG C, 2- products and raw materials, nitro 9-fluorenone fluorenone by-product 2,7- two nitro nitro fluorenone in 2- concentration of 5 30mg/L fluorenone within the scope of a good separation effect, there was a good linear relationship between peak area and concentration. The correlation coefficient is 0.9985; the average recovery rate of value more than 99%, the relative standard deviation is less than 1%. The results show that the method is simple, high precision and accuracy, suitable for measuring the industrial production of the 2- nitro fluorenone content.
