Development of a rapid spectrophotometry method for analysis of furfuraldehyde in transformer oil as an indication of paper ageing
Furfuraldehyde (FFA) has been measured colorimetrically in gas oil and hydrocarbon oil. The method is based on reaction between FFA and aniline acetate solution to produce a bright pink color. The intensity of the color is measured spectrophotometrically. This rapid technique of color development was applied to the determination of FFA in transformer oil. The method is sensitive to sub-ppm FFA in transformer oil. The results are comparable with those obtained using the high-performance liquid chromatography method.<>
