Embodiment Construction
[0008] Weigh 0.04 to 1.0 g of the oil sample and put it into a 10 ml volumetric flask, and dilute to volume with isopropanol (or n-butanol) solution. Extract 1mL sample solution into a 15ml centrifuge tube, add 1ml 2,4-dinitrophenylhydrazine solution (3.5% HCL), cover with a stopper, shake well, and heat in a water bath at 40°C for 20min. After the reaction, it was taken out and cooled to room temperature with running water, and 8 ml of 4% KOH isopropanol solution was added to develop the color. The test tube was centrifuged at 3000 rpm / min for 5 min, and the supernatant was taken to measure its absorbance at 410-425 nm.
