Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a method for producing colored flames that generate various colored flames such as red, yellow, yellow-green, green, blue, and violet by burning with a combustion device such as a gas lighter. This is related to gas fuel for use.

Conventional technology Conventionally, as gas fuel for producing colored flames, inorganic salts or organic acid salts containing specific metals that cause a flame reaction singly or in combination are dissolved in organic solvents, or combustible gases are produced without dissolving them. A solution has been proposed that allows it to be dissolved. This gas and fuel for generating a colored flame are used in a combustion device such as a gas lighter, and an inorganic salt or an organic acid salt of a metal is released into the atmosphere together with the liquefied gas, and when ignited, a colored flame is generated.

Problems to be Solved by the Invention However, not only the solubility of the inorganic salts or organic acid salts of the metals used in the above conventional examples and the organic solvent alcohols is low, but also the solubility of the inorganic salts or organic acid salts of the metals used in the above-mentioned conventional examples is low. If so, the solubility will further decrease. For this reason, 1 hour
Metal inorganic salts, etc., dissociate and precipitate due to temperature, impact, or physical behavior (rapid change from liquid phase to gas phase) during combustion with a gas lighter, resulting in nozzle clogging, etc. Less stable. The reality is that conventional gas fuels for generating colored flames have not been put into practical use due to the problems described above.

Therefore, in view of the above-mentioned circumstances, the present inventors conducted various tests and researches, and as a result of using organic metal salt compounds, metal-containing organic chelate compounds, inorganic metal salt compounds, and boric acid esters as color formers, By using a surfactant together with a color former, the color former can be solubilized by emulsification and complexation, and can be dissolved in a stable state in flammable/flammable gases, and volatility and sublimation properties can be improved. Furthermore, it was discovered that it is possible to impart a moistening effect and a mouth-feeling effect during combustion, and based on this, it is possible to prevent clogging of the nozzle of gas lighters, etc., to ensure reliable ignition, and to use it in a stable state. It is an object of the present invention to provide a gas fuel for producing colored flames that can be used to produce colored flames.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to use at least one of an organic metal salt compound, a metal-containing organic chelate compound, an inorganic metal salt compound, and a boric acid ester. One type is dissolved together with a surfactant in a flammable gas that vaporizes under atmospheric pressure.

action The effects of the above technical means are as follows.

At least one of organic metal salt compounds, metal-containing organic chelate compounds, inorganic metal salt compounds, and boric acid esters, which are color formers that exhibit a flame reaction, is emulsified and complexed in a flammable gas using a surfactant. It is possible to solubilize the color former and prevent dissociation, separation, and precipitation of the color former.

Furthermore, since the surfactant has a wetting effect, the color former can be stably supplied to a nozzle of a gas lighter or the like. Further, the surfactant helps the volatility and sublimation of the coloring agent. Therefore, it is possible to prevent clogging of the nozzle of a gas lighter, etc., and to generate a colored flame in a stable state. Furthermore, since the activator has a mouth-feeling effect when the above-mentioned color former is burnt, 1
A bright colored flame can be generated.
