Abstract
Description
La présente invention concerne des composés utilisables pour la lutte contre l'incendie.The present invention relates to compounds which can be used for fire fighting.
L'invention concerne notamment l'utilisation de composés extincteurs choisis parmi les hydrogénofluoroalcanes.The invention relates in particular to the use of extinguishing compounds chosen from hydrogenofluoroalkanes.
Dans le domaine de l'extinction et de la lutte contre l'incendie, on utilise essentiellement des chlorobromofluoroalcanes et des bromofluoroalcanes.In the field of extinction and fire fighting, chlorobromofluoroalkanes and bromofluoroalkanes are mainly used.
On utilise tout particulièrement le trifluorobromométhane, le difluorochlorobromométhane et le 1,1,2,2- tétrafluoro 1,2-dibromoéthane.Trifluorobromomethane, difluorochlorobromomethane and 1,1,2,2-tetrafluoro 1,2-dibromoethane are used in particular.
Ces composés présentent une grande efficacité extinctrice et une toxicité humaine très faible. Ils sont utilisés notamment pour la protection de locaux que le personnel peut avoir des difficultés à évacuer.These compounds have high extinguishing efficiency and very low human toxicity. They are used in particular for the protection of premises that staff may have difficulty evacuating.
Ils sont également utilisés dans des locaux où se trouvent des appareillages électriques et électroniques sensibles à la corrosion (salle informatique, centraux téléphoniques).They are also used in premises where there are electrical and electronic equipment susceptible to corrosion (computer room, telephone exchanges).
Cependant ces composés sont suspectés être responsables de la diminution de la couche d'ozone stratosphérique qui assure une protection contre certaines radiations. Ils possèdent des ODP (ozone depletion potential) élevés, et de ce fait, sont cités dans le Protocole de Montréal.However, these compounds are suspected of being responsible for the reduction of the stratospheric ozone layer which provides protection against certain radiations. They have high ozone depletion potential (ODP) and are therefore listed in the Montreal Protocol.
Ce protocole résulte de récentes discussions internationales sur l'environnement et engage les pays signataires à réduire la production et la consommation de tels composés.This protocol is the result of recent international discussions on the environment and commits the signatory countries to reduce the production and consumption of such compounds.
On a maintenant trouvé pour remplacer ces composés écotoxiques un composé extincteur peu destructeur de la couche d'ozone stratosphérique, répondant à la formule générale :
Cn Hm Fx I
dans laquelle n est un nombre entier allant de 1 à 6, m et x sont des nombres entiers au moins égaux à 1 et la somme (m + x) est égale à 2n ou 2n + 2 ; à l'exclusion des tétrafluoroéthanes et du pentafluoroéthane.We have now found to replace these ecotoxic compounds an extinguishing compound which is not very destructive of the stratospheric ozone layer, corresponding to the general formula:
C n H m F x I
in which n is an integer ranging from 1 to 6, m and x are whole numbers at least equal to 1 and the sum (m + x) is equal to 2n or 2n + 2; excluding tetrafluoroethanes and pentafluoroethane.
Parmi les composés de formule I on préfère ceux dans lesquels m est égal à 1 ou 2.Among the compounds of formula I, those in which m is equal to 1 or 2 are preferred.
Parmi les composés de formule I on citera plus particulièrement le 1,1,1,2,3,3,3-heptafluoropropane, le 1,1,1,2,2,3,3,4,4-nonafluorobutane et le 1,1,1,3,3,3-hexafluoropropane.Among the compounds of formula I, mention will be made more particularly of 1,1,1,2,3,3,3-heptafluoropropane, 1,1,1,2,2,3,3,4,4-nonafluorobutane and 1 , 1,1,3,3,3-hexafluoropropane.
L'efficacité extinctrice est généralement mesurée selon la méthode dite du Cup Burner.Extinguishing efficiency is generally measured using the so-called Cup Burner method.
Cette méthode indique le pourcentage minimum de composé extincteur (mesuré en volume) dans un mélange air plus composé extincteur nécessaire pour éteindre un combustible liquide enflammé.This method indicates the minimum percentage of extinguisher compound (measured by volume) in an air plus extinguisher compound mixture required to extinguish an ignited liquid fuel.
Plus la valeur du Cup Burner est faible, plus le composé extincteur est efficace.The lower the value of the Cup Burner, the more effective the extinguishing compound.
Les composés selon l'invention possèdent des valeurs de Cup Burner qui sont faibles (en général inférieures à 10 %) et par conséquent présentent un pouvoir extincteur élevé.The compounds according to the invention have low Cup Burner values (generally less than 10%) and therefore have a high extinguishing power.
A titre indicatif, le trifluorobromométhane, qui est actuellement l'un des agents extincteurs les plus utilisés a une valeur de Cup Burner égale à 4,2 % mais est cité dans le Protocole de Montréal.As an indication, trifluorobromomethane, which is currently one of the most widely used extinguishing agents, has a Cup Burner value equal to 4.2% but is cited in the Montreal Protocol.
Les composés selon l'invention ont l'avantage de présenter des ODP nuls. Cela signifie qu'ils sont dépourvus d'effet destructeurs vis à vis de la couche d'ozone stratosphérique.The compounds according to the invention have the advantage of having zero ODPs. This means that they have no destructive effect on the stratospheric ozone layer.
L'ODP est défini comme le rapport entre l'abaissement de la colonne d'ozone enregistrée lors de l'émission d'une masse unitaire de la substance et le même abaissement pour le trichlorofluorométhane choisi comme référence (ODP = 1). A titre indicatif, le trifluorobromométhane a un ODP de 10.The ODP is defined as the ratio between the reduction in the ozone column recorded during the emission of a unit mass of the substance and the same reduction for the trichlorofluoromethane chosen as reference (ODP = 1). As an indication, trifluorobromomethane has an ODP of 10.
Les composés selon l'invention sont peu corrosifs et possèdent une faible toxicité humaine.The compounds according to the invention are not very corrosive and have low human toxicity.
Ils peuvent être utilisés pour lutter contre les incendies selon les mêmes techniques que le trifluorobromométhane et le difluorobromochlorométhane.They can be used to fight fires using the same techniques as trifluorobromomethane and difluorobromochloromethane.
Ainsi, ils peuvent être avantageusement utilisés pour la protection des locaux par la technique dite du noyage total.Thus, they can be advantageously used for the protection of premises by the technique known as total flooding.
Ils peuvent être pressurisés avec des gaz inertes tels que l'azote ou le tétrafluorométhane ce qui permet d'augmenter leur vitesse de déchargement.They can be pressurized with inert gases such as nitrogen or tetrafluoromethane, which makes it possible to increase their unloading speed.
Ils peuvent également être employés dans les techniques de l'extincteur portable.They can also be used in portable fire extinguisher techniques.
Les exemples suivants illustrent l'invention.The following examples illustrate the invention.
L'efficacité extinctrice est mesurée par la methode dite du Cup Burner dans le projet de norme ISO/DIS 7075-1.Extinguishing efficiency is measured by the so-called Cup Burner method in the draft ISO / DIS 7075-1 standard.
Le combustible liquide utilisé est l'éthanol.The liquid fuel used is ethanol.
Les résultats sont rassemblés dans le tableau ci-après.
