A method for determining the end point of an alkylated gasoline by gas chromatography

Abstract

This invention discloses a method for determining the final boiling point of alkylated gasoline by gas chromatography, comprising the following steps: (1) taking several alkylated gasoline samples, separating the components of the alkylated gasoline samples by capillary gas chromatography and accurately quantifying each component; detecting the final boiling point of the above alkylated gasoline samples by atmospheric distillation, and recording the corresponding final boiling point data of the alkylated gasoline samples; (2) using SPSS software to analyze the Pearson correlation coefficient between the content of each component of the alkylated gasoline sample and the final boiling point, and determining the content of the component that is significantly correlated with the final boiling point as the fitting independent variable; (3) using a linear support vector machine to fit the linear relationship between the component content and the final boiling point determined in step (2), and obtaining the fitted data model; (4) using the fitted data model obtained in step (3), the final boiling point of the alkylated gasoline sample to be tested can be calculated in gas chromatography.
