SOLID FUEL BURNING WITH A BLUE FLAME LIQUID FUEL BURNING WITH A BLUE FLAME FUEL TO BE DILUTED TO BURN WITH A BLUE FLAME.

Abstract

La présente invention concerne un combustible solide et un combustible liquide brûlant avec une flamme d'un bleu plus ou moins soutenu en fonction du pourcentage de chlorure cuivrique CuCl2-2H2O et du pourcentage de dichloroéthane, par rapport aux proportions d'alcools pour les liquides et de combustibles solides du type héxaméthylène tétramine, métaldéhydes, etc... pour les combustibles solides. Pour ces derniers, le trempage du chlorure cuivrique dans le dichloroéthane, puis le séchage par évaporation de l'hydrocarbure halogéné (dichloroéthane) suffit à modifier la composition du chlorure cuivrique, pour qu'aggloméré à un combustible solide, ou encore dilué en solution dans un combustible liquide dans lequel il peut se dissoudre, il brûle ensuite avec une flamme bleue. La densité du bleu dépendant entièrement de la concentration en CuCl2-2H2O dans la composition.

Description

Solid fuel that burns with a blue flame. Liquid fuel that burns with a blue flame. Fuel that needs to be diluted so that it burns with a blue flame. The present invention relates to a solid fuel and a liquid fuel burning with a flame of a more or less intense blue depending on the percentage of cupric chloride CuCl2-2H20 and the percentage of dichloroethane, relative to the proportions of alcohols for the liquids and of solid fuels of the type hexamethylene tetramine, metaldehydes, etc. for the solid fuels. For these latter products, soaking cupric chloride in dichloroethane, then drying it by evaporation of the halogenated hydrocarbon (dichloroethane), is sufficient to modify the composition of the cupric chloride so that, when agglomerated with a solid fuel, or diluted in a liquid fuel in which it can dissolve, it then burns with a blue flame. The intensity of the blue flame depends entirely on the concentration of CuCl₂H₂O in the mixture. It is known that adding a small amount of a halogenated hydrocarbon (dichloroethane, for example) in solution with chlorides—except those of copper—ethylene glycol, and alcohols, helps stabilize a colored flame. For copper, dibromoethane is preferable, as dichloroethane turns the green flame obtained with cupric chloride dissolved in alcohols blue. The object of the present invention is to clarify three essential points concerning blue flames: a- For solid fuels, a simple soaking cupric chloride in dichloroethane, modifies it so that once dried and ground then mixed and compressed with a fuel solid, with a minimum proportion of 15% by weight compared to 85% hexamethylene tetramine (with or without binder), the composition The resulting product burns with a blue flame. To obtain a deep blue, we need to push the proportion of CuCl2-2H2O at 25%. And 75% HMT b- If a mixture is pelletized (using a pelletizing machine) of effervescent product (identical to those used (available in pharmacies) with copper chloride powder that pre-soaked (then dried) in dichloroethamine no, the resulting lozenge, diluted in alcohol ethyl or methyl, at a rate of 5% (blue clear diaphanous) at 25% (deep "royal" blue) in weight, will allow the diluted composition obtained to burn with a blue flame. The product effervescent being possible. c- If an aqueous or al solution is concentrated cool, supersaturated with CuCl2-2H2O at a rate of 50% to 80%, and that the copper chloride is soaked than in dichloroethane before drying, or even though we add 1% to 5% to the solution In liquid form, dichloroethane will be obtained a composition which, diluted in 75% to 90% of alcohols, will burn with a colored flame blue, the density of which will depend on the proportion of copper chloride in alcohol. If we add this composition to 50% gasoline purified, hexane, etc. in a wick lamp, A blue and white flame will be obtained.

Claims

RN7H:ND I CAT I ONS 1) Composition and mixing process for obtaining a solid or liquid fuel burning with a blue flame, characterized in that the addition by soaking of cupric chloride CuCl22H20 in dichloroethane, even once the latter has evaporated, allows the CuCl2-2H20 to burn with a blue flame instead of a green flame. 2) Composition and process according to claim 1, characterized in that the only soaking and then drying of the cupric chloride powder allows the change of flame color, provided that the soaking is carried out in a halogenated hydrocarbon of the dichloroethane type. 3) Process according to claims I & 2, characterized in that the proportion of copper chloride, varying from 5% to 30%, either in a solution of alcohols (ethyl, methyl), or mixed with a solid fuel such as HMT (hexamine), determines the density of the blue obtained, from sky blue to so-called "royal" blue. 4) A process according to any one of the preceding claims, characterized in that a CuCl2-2H20 pellet, soaked in dichloroethane and then dried, then ground and mixed with an effervescent product of the pharmaceutical type, or even without an effervescent product, will, by dilution in an alcohol, between 5 and 30% by weight, produce a fuel which will burn with a blue flame. 5) A process and composition according to claims 1, 2, and 3, characterized in that either soaking and then drying in dichloroethane is carried out, or the latter can be added in liquid form, provided that at least 15 to 30% of CuCl2-2H2O is diluted in alcohol and less than 5% dichloroethane is added to the solution. Any proportion below 15% produces a blue that is too light and translucent to be distinguished from the natural flame of pure methanol, for example. If more than 5% dichloroethane is added, the blue flame is overlain by a red flame due to the combustion of the halogenated hydrocarbon, and this flame is undesirable. 6) A method according to any one of the preceding claims, characterized in that if a variable proportion (20 / 80%) of the above-described liquid fuel and purified gasoline of the hexane type are added to a wick lamp (cotton or fiberglass), a 50% blue and 50% white flame will be obtained, because these fuels do not mix and rise separately, by capillary action, in the wick. 7) A method according to any one of the preceding claims, characterized in that the solid mixture CuCl2-2H2O (15 to 30%) and HMT (70 to 85%), with or without binder, provided that the chloride has been soaked in dichloroethane and then dried before mixing, will burn with a blue flame.
