Definitions
- the extinguishing of fires of combustibles such as coal, brown coal, and partlcularly of finely divided comb'uistibles, such as coal 5 example, soaps or saponin, but the sulphonation products of organic compounds, namely sulphuric esters or sulphonic acids and particularly their salts, which are equivalents to the said esters or acids for the purposes of the present invention, are most efiicient.
- the said sulphuric esters and sulphonic acids comprise Turkey red oil and similar ac1d sulphuric esters of fats and oils or fatty acids and the sulphonic acids of aliphatic,
- cycloaliphatic, partially hydrogenated aromatic and monoor poly-nuclear aromatic compounds and especially those of the cyclic compounds which are substituted by alkyl or aralkyl radicals.
- mixtures composed of such sulphonation products or the mixtures obtainable by sulphonating mineral oils or tars or fractions thereof can be favorably employed.
- These materials can be employed as such or in the form of their salts and can be either added to the water, or the readily inflammable substances canbe sprayed therewith so that, in the case of 1gnition, the burning substances are thoroughly and quickly penetrated by the water sprayed thereon and thereby wetted.
- the solutions according to the present invention are preferably sprayed by means of a nozzle onto the burning material in order to avoid flame jets.
- the amount of the material to be employed which is capable of reducing the surface tension of water can be varied within wide limits, even a very small percentage by Serial No. 345,223, and in Germany March 14, 1928.
- E wample 1 From 1 to 2 parts of the sodium salt of a naphthalene sulphonic acid containing one or more propyl or butyl groups in its molecule are added to each 100 parts of water. On extinguishing fires, such as burning brown coal, by spraying the said mixture onto the burning material, the mixture penetrates the burning material much more quickly than pure water, so that a striking result as regards extinction is produced.
- a naphthalene sulphonic acid containing one or more propyl or butyl groups in its molecule are added to each 100 parts of water.
- fires such as burning brown coal
- the mixture penetrates the burning material much more quickly than pure water, so that a striking result as regards extinction is produced.
- grain soap, Turkey red oil or similar compounds can be employed, but the aforesaid salts are more efficient.
- Example 2 Burning linseed is easily extinguished by adding to the water intended for extinguishing, about 1 per cent its weight of a butylated napthalene sulphonic acid, and spraying or spurting the solution onto the burning material.
- E trample 3 Burning brown coal dust deposited in a closed room is easily extinguished by introducing wet steam into the same after the steam has been loaded with a highly efficient wetting agent, such as sulphonated mineral oil or tar oil or naphthenic acid or tall oil sulphonation products, butylated, amylated or benzylated napthalene sulphonic acids or naphthalene sulphonic acids containing several of the aforesaid substituents, for example benzyl iso-propyl napthalene sulphonic acid and chlorinated sulphonic acids of the aforesaid series, for example, by passing a solution thereof or by spraying steam and the solution through a mixing nozzle.
- a highly efficient wetting agent such as sulphonated mineral oil or tar oil or naphthenic acid or tall oil sulphonation products, butylated, amylated or benzylated napthalene sulphonic acids or
- a process for extinguishing fire which comprises bringing a dilute aqueous solu tion of a highly effective wetting agent containing an acid group into contact with the burning material.
- a process for extinguishing fire which comprises bringing dilute aqueous solution of a strongly wetting sulphonation product of an organic compound into contact with the burning material.
- a process for extinguishing fire which comprises bringing a dilute aqueous solution of a strongly wetting sulphonation prod uct of a mixture or organic compounds into contact with the burning material.
- a process for extinguishing fire which comprises bringing a dilute aqueous solution of a sulphonic acid of an aromatic compound into contact with the burning material.
- a process for extinguishing fire which comprises bringing a dilute aqueous solution of a sulphonic acid of a polynuclear aromatic compound into contact with the burning material.
- a process for extinguishing fire which comprises bringing a dilute aqueous solution of a sulphonic acid of an aromatic compound containing an alkyl radicle in its molecule into Contact With the burning material.
