ている。(b) Conventional technology Conventionally, kerosene and mixtures of kerosene and light oil can be identified by adding quinizarin, coumarin, or furfural to kerosene, and when quinizarin is added, the coumarin is extracted with alkali and turns purple. When furfural is added, this is done by exciting it and emitting fluorescence.

至った。(d) Means for Solving the Problem In order to achieve the above-mentioned problem, the inventors conducted intensive research and conducted repeated experiments on adding dye to kerosene, and found that the basic dye was treated with alkali and washed. The fact that the dye-mixed kerosene obtained by dissolving the oil-soluble dye obtained by this process in kerosene is colorless, and the fact that a small amount of an alcohol or organic acid aqueous solution that is poorly soluble in kerosene is added to the oil-soluble dye and kerosene mixture and shaken. The present invention was based on the discovery that the phase of the colored alcohol or organic acid aqueous solution separates when the solution is allowed to stand after cooling.

For forming a phase-separated colored layer, for example, methanol, ethylene glycol, propylene glycol, acetic acid aqueous solution, or a mixture thereof can be used. In addition, this kerosene poorly soluble alcohol or organic acid water + 1# liquid is usually added in an amount of 5 to 10% by volume to kerosene or a mixture of kerosene and light oil.
The mixture is well mixed by stirring, shaking, etc., and then allowed to stand for phase separation. Thereafter, kerosene is detected based on the coloration or concentration of the phase-separated alcohol or organic acid aqueous solution layer.
