(産業上の利用分野)
この発明は鑑賞、照明、信号用などに有用な有色炎を発
生する燃料に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a fuel that generates a colored flame useful for viewing, illumination, signaling, and the like.
(従来の技術)
従来、美的効果を目的としてローソクやランプなどの炎
に色をつけることが種々試みられている。(Prior Art) Various attempts have been made to color the flames of candles, lamps, etc. for the purpose of aesthetic effects.
この場合、炎に色をつけるためには、これらの燃料中に
例えばアルカリ金属の塩などの炎色剤を溶解し、燃焼に
伴なう金属元素特有の炎色反応を発生させることが行な
われている。In this case, in order to color the flame, a flame coloring agent such as an alkali metal salt is dissolved in these fuels to generate a flame color reaction unique to the metal elements that accompanies combustion. ing.
しかしローソクの場合、パラフィン、ステアリン酸、密
ロウなどのローソク原料は一般に炎色剤を溶解し難く、
また炎の中に生ずる多量の有能炭素が発する強い黄色光
のため1こ炎色効果が妨げられる欠点があった。However, in the case of candles, candle raw materials such as paraffin, stearic acid, and beeswax generally have difficulty dissolving flame coloring agents.
Another drawback is that the strong yellow light emitted by the large amount of active carbon produced in the flame hinders the flame color effect.
一方、アルコールでは各種の炎色剤の溶解が可能であり
、またアルコール自体の炎色が淡いため、炎色剤による
炎色効果を妨げない利点はあるが、燃焼が継続するうち
にアルコールランプの芯に炎色剤の結晶や固形の燃焼残
漬が付着し、芯の毛細管効果が低下してアルコールの吸
い上げが悪くなり、次第に炎が小さくなると同時に炎色
が失われ、遂には燃焼が中断する欠点があった。On the other hand, alcohol can dissolve various flame coloring agents, and alcohol itself has a pale flame color, so it has the advantage of not interfering with the flame coloring effect of the flame coloring agent. Crystals of the flame coloring agent and solid combustion residue adhere to the wick, reducing the capillary effect of the wick and making it difficult to absorb alcohol, causing the flame to gradually become smaller and lose its color, eventually stopping combustion. There were drawbacks.
(発明が解決しようとする問題点)
本発明はこの欠点をなくし、燃焼中に芯などに固形物が
形成あるいは付着しないような燃料成分とすることによ
り定常的に燃焼を継続させ、かつ炎色をさらに向上させ
ようとするものである。(Problems to be Solved by the Invention) The present invention eliminates this drawback and uses fuel components that do not form or adhere to the wick etc. during combustion, allowing for steady combustion and flame color. The aim is to further improve this.
(問題点を解決するための手段)
本発明は脂肪族低級アルコールを主剤とする液体燃料と
、炎色剤ならびに炎色剤の共融化剤よりなる有色炎発生
用燃料である。(Means for Solving the Problems) The present invention is a colored flame-generating fuel comprising a liquid fuel containing an aliphatic lower alcohol as a main ingredient, a flame coloring agent, and a eutectic agent for the flame coloring agent.
本発明に用いる燃料の主剤となる脂肪族低級アルコール
トシてはメチルアルコール、エチルアルコール、プロピ
ルアルコール、イソプロピルアルコール、エチレングリ
コールなとで、燃焼時の炎色を阻害しないよう炭素数の
少ないものが望ましい。The aliphatic lower alcohol which is the main ingredient of the fuel used in the present invention is methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, ethylene glycol, etc., and preferably has a small number of carbon atoms so as not to inhibit the color of the flame during combustion. .
また炎色反応により炎を着色する炎色剤としては、例え
ばアルカリ金属、アルカリ土金属、銅などの炎色反応を
起こす金属の化合物などで、主剤のアルコールに可溶の
ものが望ましく、その例としては塩化リチウム、塩化ス
トロンチウム、塩化カルシウム、塩化インジウム、塩化
銅、ふり化カリウム、よう化カリウム、硝酸リチウム、
炭酸セシウムなど、およびこれらの混合物があげられる
。In addition, the flame coloring agent that colors the flame by a flame color reaction is preferably a compound of a metal that causes a flame color reaction, such as an alkali metal, an alkaline earth metal, or copper, and is soluble in the main alcohol. Examples include lithium chloride, strontium chloride, calcium chloride, indium chloride, copper chloride, potassium fluoride, potassium iodide, lithium nitrate,
Examples include cesium carbonate, etc., and mixtures thereof.
その配合量は特に制限はないが通常は燃料の1ないし1
0%程度でよい。なお本発明に用いる燃料には、炎色剤
の溶解性や燃焼時の発色性を改善するなどの目的で各種
の溶剤、例えば水、/’%ロゲン化炭化水素、脂肪族多
価アルコールなどを混合せしめてもよい。There is no particular limit to its blending amount, but it is usually 1 to 1 part of the fuel.
It may be about 0%. The fuel used in the present invention may contain various solvents, such as water, /'% halogenated hydrocarbons, aliphatic polyhydric alcohols, etc., for the purpose of improving the solubility of the flame coloring agent and the color development during combustion. They may be mixed.
本発明者らは、これら脂肪族低級アルコールを主剤とす
る液体燃料と炎色剤よりなる燃料に、炎色剤の共融化剤
を加えた場合には、アルコールランプのように芯を用い
て燃焼させても芯の上部で生じる炎色剤の結晶や固形の
燃焼残漬による毛細管現象低下のトラブルが少なくなり
、このため燃焼が長時間継続し、また炎色および光度も
向上することを見出だした。The present inventors discovered that when a eutectic agent for the flame coloring agent is added to a fuel consisting of a liquid fuel mainly composed of an aliphatic lower alcohol and a flame coloring agent, the fuel can be burned using a wick like an alcohol lamp. It was discovered that even if the flame colorant crystals and solid combustion particles remain in the upper part of the wick, the problem of reduced capillary action caused by flame coloring agent crystals and solid residues is reduced, and as a result, combustion continues for a long time, and the flame color and luminous intensity are improved. Ta.
ここに本発明でいう炎色剤の共融化剤とは、それが炎色
剤とともに芯によって吸い上げられ、燃焼熱によって加
熱されたとき、炎色剤などと共融現象を起こして融点の
一層低い混合物を形成する物質を言う。Here, the eutectic agent of the flame coloring agent referred to in the present invention refers to the eutectic agent of the flame coloring agent, which when it is sucked up by the wick together with the flame coloring agent and heated by the heat of combustion, causes a eutectic phenomenon with the flame coloring agent, etc., and has a lower melting point. Refers to substances that form a mixture.
本発明者らはこの炎色剤に対する共融化剤として尿素、
グアニジンならびにこれらの塩、誘導体が硝酸リチウム
などの炎色剤に対して特に優れたちのであることを見出
だした。これら共融化剤の配合量は、併用する炎色剤の
種類と配合量にもよるが、概ね炎色剤に対して0.1〜
10重量比の範囲でよい。The present inventors used urea as a eutectic agent for this flame coloring agent.
It has been found that guanidine and its salts and derivatives are particularly effective against flame coloring agents such as lithium nitrate. The blending amount of these eutectic agents depends on the type and blending amount of the flame colorant used together, but is generally 0.1 to 0.1 to the flame colorant.
The weight ratio may be in the range of 10% by weight.
本発明の有色炎発生用燃料は、従来のアルコールランプ

吸い上げられるためと推定される。例えば尿素は一般に
無機硝酸塩などと共融混合物を形成しやすく、比較的低
温で液状を保ち、流動性を有するので、この効果がある
ものと思われる。The colored flame-generating fuel of the present invention can be burned for a long time in a wick-based combustion device like a conventional alcohol lamp. It is not clear why there are fewer troubles due to reduced capillarity when the fuel of the present invention is burned, but the flame coloring agent, its eutectic agent, alcohol, and their reaction products are heated and eutectic to form a liquid. It is presumed that this is because the liquid is sucked up smoothly. For example, urea is thought to have this effect because it generally tends to form a eutectic mixture with inorganic nitrates and the like, remains liquid at relatively low temperatures, and has fluidity.

It produced a bright red flame and continued burning until the last of its fuel was consumed. During this time, a lump of liquid eutectic material that boiled or decomposed was observed at the top of the wick.

よりも炎色剤の量を少なくすることがでトる。(Effects) In the colored flame generating fuel of the present invention, the flame coloring agent stays in liquid form at the top of the wick, so the density of the flame color increases and the luminous intensity also increases. In other words, less flame colorant can be used than with conventional fuels to provide the same flame color effect.
