とは不可能であった。(Problem to be Solved by the Invention) However, when fossil fuel is used as a liquid fuel, when it is combusted, it emits an orange to yellowish flame color derived from the luminescence of free carbon. Coloring of flames is difficult with methods that use reactions, as the color is lost. In experiments conducted by the present inventor using petroleum-based liquid fuel and coal-based liquid fuel as liquid fuels, the entire flame was colored orange, making it impossible to visually recognize the flame color reaction caused by the coloring agent.

However, if sufficient coloring brightness cannot be obtained and the concentration of the coloring agent is increased in order to obtain sufficient coloring brightness, a large amount of white fine particles of boron oxide, which is a combustion product, will be generated and will be scattered to the surrounding area. become.

調製した。(Means for Solving the Problems) In order to solve the above problems, the present invention provides a method for generating green flame by dissolving a boric acid ester and an oxamic acid ester in a liquid fuel whose main component is an alcohol having 1 to 4 carbon atoms. A liquid fuel was prepared.

及び第２表に示すようにホウ酸エステル濃度を３０ 、
０ｖｏ１％（約３２ｗｔ％）以上の濃度か必要になる。The reason why we use liquid fuel whose main component is alcohol is that the fuel itself does not have a noticeable flame color when it burns, so in order to reduce the white particulates of boron oxide, the color is visible even when the concentration of boric acid ester is low. This is to make it possible. The alcohol used in this liquid fuel has carbon atoms of 1 to 4. When the number of carbon atoms exceeds 5, the orange or yellowish coloration resulting from the high-temperature luminescence of free carbon becomes stronger, making it difficult to visually recognize the color, and when the number of carbon atoms increases, the odor characteristic of fuel becomes noticeable. give discomfort. Furthermore, by adding oxamate ester, which has a negative effect on ignition performance when used as a fuel for lighters, as the boiling point and flash point rise as the number of carbon atoms increases, the color former boric acid ester Sufficient color brightness can be obtained even if the concentration is lowered, and smoke emission during combustion is also reduced.
In other words, according to experiments, in order to obtain sufficient color brightness to be visible under daylight, simply dissolving boric acid ester in alcoholic liquid fuel with a low carbon number requires the steps shown in Tables 1 and 2. The boric acid ester concentration was set to 30 as shown in
A concentration of 0vo1% (approximately 32 wt%) or higher is required.

度を増加させて充分な視認性を付与することができる。Table 1 Table 2 For example, by adding and dissolving an oxamate ester in alcoholic liquid fuel with a borate ester concentration of 20.0vo1% or less, which normally has low visibility, the brightness of the flame can be increased sufficiently. It is possible to provide high visibility.

る。At this boric acid ester concentration, since smoke generation due to boron oxide is originally low, it becomes possible to increase color brightness and improve visibility while keeping smoke generation low.

給が行われて橙色系炎色の発生か抑制される。The following is considered to be the effect of this oxamic acid ester. ■The high combustion heat of the oxamic acid ester itself increases the combustion temperature of the flame, increasing the coloring efficiency of the coloring agent. - Due to the combustion of the oxamic acid ester, oxygen is supplied even to the reducing flame area, which originally lacks oxygen supply, and the occurrence of orange flame color is suppressed.

に有効である。This oxamic acid ester produces its effect in a small amount, and the effect of increasing color brightness is recognized even when added at about 0.05 wt % to the alcoholic liquid fuel in which the boric acid ester is dissolved. The effect remains the same even if the amount added is increased, but if added in large amounts, the storage stability will be reduced, so adding in a range of 0.05 to 20 wt% is sufficiently effective.
