Abstract

The invention discloses a diesel family boundary substance mixed standard solution. The solution is characterized in that the boundary substances comprise n-decane, n-undecane, n-dodecane, n-tridecane, n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nondecane, n-eicosane, n-hendecane, n-docosane, n-tricosane, n-tetradecane and n-pentadecane. A brand-new analysis means isprovided for appearance of a comprehensive two-dimensional gas chromatography technology, comprehensive ethnic analysis can be carried out on diesel oil, accurate measurement can be carried out on some specific compounds, and a boundary substance standard solution and a preparation method play one of key roles.

Description

technical field [0001] The invention belongs to the field of diesel group boundary substances, and in particular relates to a mixed standard solution of diesel group boundary substances and a preparation method thereof. Background technique [0002] The aromatics content in diesel is one of the factors that affect exhaust emissions and fuel combustion performance (expressed in cetane number). With the increasingly stringent requirements for environmental protection, the requirements for total aromatics in diesel oil, especially polycyclic aromatic hydrocarbons, are becoming more and more stringent. Therefore, accurate analysis methods are needed to determine the total aromatics and polycyclic aromatic hydrocarbons content of products. The main existing methods are as follows: [0003] GB / T11132 is used for the determination of aromatics in diesel, but it is not suitable for fractions with a boiling point greater than 315°C and the accuracy is low. SH / T 0606 can determine t...
