【発明の詳細な説明】
（産業上の利用分野）
本発明は、着色火炎を安定して発生する液体燃料の組成
に関し、特にオイルライターに充填して使用する液体燃
料に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a composition of a liquid fuel that stably generates a colored flame, and more particularly to a liquid fuel used by being filled into an oil lighter.
（従来の技術）
着色火炎を発生させるに際しては、炎色反応の試験方法
を利用して、炎色反応を呈する金属元素等を火炎の中に
投じる方法が考えられる。(Prior Art) When generating a colored flame, a method can be considered in which a flame color reaction test method is utilized and a metal element or the like exhibiting a flame color reaction is thrown into the flame.
本来、炎色反応においては、炎色反応を呈する金属元素
等を水等に溶解し、イオン化状態にあるものを火炎中に
投じることにより、熱励起させ、その金属元素固有の波
長の光を放出させている。Originally, in a flame reaction, a metal element that exhibits a flame reaction is dissolved in water, etc., and the ionized substance is thrown into a flame to be thermally excited and emit light with a wavelength unique to that metal element. I'm letting you do it.
ここで炎色反応を呈する金属元素の殆どは常温で固体で
あるため、この反応において最も重要な点は、炎色反応
を呈する金属元素等を溶媒に溶解してイオン化させるこ
とにある。Since most of the metal elements that exhibit a flame reaction are solid at room temperature, the most important point in this reaction is to dissolve the metal elements that exhibit a flame reaction in a solvent and ionize them.

しかしながらこれらの金属元素を含む化合物の多くは水

ター用燃料に対しては、主燃料である有機溶媒への溶解
性が最重要課題となり、この溶解性が使用する化合物の
基準になる。(Problem to be solved by the invention) However, many of the compounds containing these metal elements are water-soluble, so when they are thrown into a flame in the form of an aqueous solution, as in qualitative analysis, there are no problems. However, if it were to be used as a fuel to generate a colored flame, it would need to be dissolved in an organic solvent, and most water-soluble compounds are not suitable for this purpose. Therefore, the most important issue for oil lighter fuels is their solubility in the organic solvent that is the main fuel, and this solubility becomes the criterion for the compounds used.
一方、主燃料となる有機溶媒に対する選択基準は、燃焼
時の発色にある。燃焼具用の燃料として一般に用いられ
ている化石燃料は、燃焼に際して遊離炭素の高温発光に
由来する橙色〜黄色系の炎色を強く発するため、通常の
炎色反応を利用した方法では、炎色反応による発色より
も燃料の燃焼による発色が強過ぎて、炎色反応を視認で
きない、という不都合が発生する。On the other hand, the selection criterion for an organic solvent to be used as a main fuel is based on color development during combustion. Fossil fuels, which are commonly used as fuel for combustion tools, emit a strong orange-yellow flame color due to the high-temperature luminescence of free carbon when they are combusted. The color produced by the combustion of the fuel is much stronger than the color produced by the reaction, resulting in the inconvenience that the flame color reaction cannot be visually recognized.

る。(Means and effects for solving the problem) In order to solve the above problem, first, regarding the organic solvent that is the main fuel,
Since it is necessary not to interfere with the flame reaction and to be easily ignited with a flint when filled into a lighter, it is an absolute requirement that it have sufficient flammability. As a result of various studies and selections of organic solvents that satisfy this condition, it has been found that the organic solvents are limited to lower alcohols having 1 to 4 carbon atoms. In other words, with ordinary petroleum-based liquid fuel, the flame reaction is significantly hindered due to the reasons mentioned above;
The above-mentioned alcohols also have the problem of not only interfering with the flame reaction, but also reducing ignitability and generating off-flavors, so they cannot be used as the fuel in this case. Therefore, it is required to use a lower alcohol having 1 to 4 carbon atoms as the organic solvent of the liquid fuel for producing a colored flame that is filled into an oil lighter.

した結果、下記に示す様な化合物に限定されることが判
明した。Next, for compounds containing metal elements etc. that are dissolved in the main fuel and exhibit a flame reaction, the main fuel has 1 to 4 carbon atoms.
The absolute requirements are that the fuel be dissolved in lower alcohols, exhibit stable color development during combustion, and not leave large amounts of reaction products such as carbides and oxides on the combustion wick. As a result of various studies and selections of compounds that meet these conditions, it has been found that the compounds are limited to those shown below.

However, the former is excluded because reaction products are generated and adhered to the wick surface, and the latter generates a strange odor (fireworks) when burned.
