Introduction

Hydrocracking, hydrotreating and other processes to produce jet fuel, the need to add a certain concentration of 2,6-di-tert-butyl-p-cresol antioxidant to mention High jet fuel storage stability and oxidation stability. 2,6-Di-tert-butyl-p-cresol antioxidant in jet fuel is fast, accurate and reliable Determination of jet fuel production, quality evaluation and safe use of great significance. 2,6-di-tert-butyl-p-cresol in jet fuel Determination of content - Differential pulse voltammetry Warning --- personnel using this standard should have formal laboratory work experience. The use of this standard may involve some danger Materials, equipment and operations, this standard does not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures Shi, and ensure compliance with the conditions of the relevant state laws and regulations.

1 Scope

This standard specifies the use of differential pulse voltammetry jet fuel 2,6-di-tert-butyl-p-cresol antioxidant method. This standard applies to 2,6-di-tert-butyl-p-cresol content of 8mg/L ~ 31mg/L of jet fuel. This standard can also be used beyond the scope of jet fuel 2,6-di-tert-butyl-p-cresol determination, but the precision did not do inspection.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Voltammetry voltammetry Electrochemical analysis based on the measurement of the current-voltage relationship (volt-ampere characteristic curve) during electrolysis using solid electrodes. 3.2 Differential pulse voltammetry differentialpulsevoltammetry Using a solid electrode, a fixed voltage pulse with a smaller amplitude is periodically superimposed on a DC voltage linearly increasing with time to Determination of electrolysis process before and after the addition of current difference between the voltage - voltage based electrochemical analysis. 3.3 Composite electrode compositeelectrode An electrode that encapsulates a working electrode, an auxiliary electrode and a reference electrode on one electrode body.

4 Method summary

Jet fuel was added to a specific electrolyte solution, using the specified composite electrode, differential pulse voltammetry 2,6-di-tert-butyl-methyl Determination of phenol antioxidants. Differential pulse voltammetry analysis, when the working electrode voltage is higher than the oxidation potential of the antioxidant, the antioxidant is oxygen As a result, the anodic current increases, forming an oxidation voltammetric peak of the anode current with the change of the scanning voltage. Peak voltammetry peak current and solution resistance ......
