Problems solved by technology

However, expensive instrumentation does not allow this technique to be widely used for the routine analysis of 2,6-di-tert-butyl-p-cresol in jet fuel
[0007] In summary, there is no relatively mature and easy method for determining the content of antioxidants in jet fuel

Embodiment 1

[0032] The No. 3 jet fuel containing the antioxidant 2,6-di-tert-butyl-p-cresol and the concentration in the range of 10mg / L-30mg / L was used as the sample to be tested.

[0033] Measuring conditions: instrument: electrochemical analyzer; electrode system: 3mm glassy carbon working electrode, Ag / AgCl non-aqueous reference electrode, 0.5mm platinum wire auxiliary electrode; electrolyte system: 0.1M KOH ethanol solution; initial voltage -0.1V, Termination voltage +0.5V, voltage increment 0.002V, amplitude 0.05V, pulse width 0.06s, sampling width 0.02s, rest time 2.0s, sensitivity 1×10 -5 .

[0034] Determination steps:

[0035] Firstly, the standard sample of antioxidant 2,6-di-tert-butyl-p-cresol was electrochemically analyzed.

[0036] Preparation of reserve standard sample: Accurately weigh 0.05g 2,6-di-tert-butyl-p-cresol in a 50ml beaker, add a little jet fuel identical to the sample, dissolve, and transfer to a 100ml volumetric flask, constant volume, to obtain The 2,6-d...

Embodiment 2

[0045] Embodiment 2: sample analysis to be tested

[0046] In the analysis of the sample to be tested, the steps are the same as in Example 1, the only difference being that the standard sample is changed to the sample to be tested.

Abstract

The method of detecting antioxidant content in jet fuel features that the antioxidant in jet fuel is extracted with alcohol solution of alkali metal hydroxide and measured in electrochemical analyzer and by means of differential pulse volt-ampere process. This method has the features of fast detection speed, simple operation, high accuracy and less interference factors. The electrochemical analyzer is portable for in-situ analysis. The present invention is especially suitable for conventional analysis.

Description

technical field [0001] The invention relates to a method for measuring antioxidant content, in particular to an electrochemical measuring method for antioxidant content in jet fuel. Background technique [0002] At present, the jet fuel produced by hydrocracking and hydrofinishing process increases year by year, and the jet fuel produced by hydrocracking and hydrofinishing process must add an appropriate amount of antioxidant such as 2,6-di-tert-butyl-p-cresol ( BHT) to ensure quality. my country stipulates that the jet fuel produced by hydrogenation should be added with antioxidant (21±3)mg / L. This regulation is basically based on the practices of the developed countries in the United States and the United States. Research by Bruce et al. showed that jet fuel generates peroxides only after the antioxidants in the fuel are depleted. Therefore, tracking and analyzing the consumption of antioxidants in fuel can predict the deterioration of fuel, and can also help fuel users ...
