| Abstract: | We carried out investigations to refine the spectrophotometric method of determining the qualitative characteristics of petroleum products. Particular attention was given to the development of an algorithm for processing spectral data which would be stable to changes in the temperature of the sample. We present the results of measurements of 50 reference unleaded gasolines. The uncertainty of the method does not exceed 0.5 oct. units. A. N.
