METHOD FOR DETERMINING THE CONTENT OF ADDITIVE "AGIDOL-1" IN JET FUEL Russian patent published in 2017 - IPC G01N33/22 

FIELD: chemistry.

SUBSTANCE: method of determining the amount of the additive "Agidol-1" jet fuel includes sampling, chromatographic separation column with a modified octadecylsilane sorbent with peak identification, defines the components of the corresponding "Agidol-1." Thus before chromatographic separation of sample is mixed with fuel containing no more than 0.1% water, methyl alcohol in a ratio of 5:1, the mixture was stirred to form an emulsion, maintained in a separatory funnel until a clear separation of the emulsion fuel and the methanol layer which is selected from methyl alcohol is distilled at a temperature of 55-60°C and a vacuum of 0.05 MPa, the remaining extract was transferred into a volumetric flask of 10 ml, the flask was adjusted to the mark with heptane, stoppered and stirred. After chromatographic separation is carried out UV detection at 210 nm, determines the peak area corresponding additive "Agidol 1", and the calibration curve constructed in the coordinates of the peak area - the concentration of the additives are the number of additive "Agidol-1" in the test fuel.

EFFECT: definition of an additive in jet fuel with high accuracy.
