Development of a Proximate IR Spectrometric Method for the Determination of Base Oil Viscosity, Viscosity Index, and Pour Point

详细

It has been proven on the example of individual hydrocarbons that IR spectrometry can be used to analyze properties of base oils. A proximate viscosity, viscosity index, and pour point determination method was developed based on quantitative IR spectrometry using the areas of two characteristic peaks and regression analysis for API-classified group 3 and 4 oils. This method can be used for quality control and real-time study of base oils.
