Definitions
- the present invention relates to a liquid hydrocarbon composition, intended in particular for use as fuel or fuel in engines and thermal machines. More specifically, the present invention relates to a composition of liquid hydrocarbons, the odor of which is improved thanks to the use of an original additive, the family of tricyclodecanes and / or tricyclodecènes. The present invention also relates to the use of such additive to improve the smell of fuels and / or to fight against bacterial proliferation in these.
- the hydrocarbon compositions, in particular fuels have a characteristic odor, particularly unpleasant for the user. This is why formulators of this type of product now seeks to mask the unpleasant odor, even even give them a pleasant smell by the use of specific additives called also additives or odor masks.
- patent application WO 91/18961 describes the use, to mask or reduce the odor of a fuel or fuel of petroleum origin, of at least one carboxylic acid ester and alcohol.
- This ester has at most 25 carbon atoms carbon, and preferably from 4 to 14 carbon atoms. It is advantageous used with a perfume composition comprising selected compounds among aldehydes, ketones, alcohols, other esters, terpenes, with which he would act synergistically.
- compositions have also been developed for the purpose of hide not so much the smell of the fuel itself, but the smell of gas of exhausts emitted during the combustion of the latter.
- US Patent 1,348,512 describes an agent masking the smells of exhaust gases and fumes from combustion of middle distillates, such as, in particular, diesel fuels or lamp oils.
- This agent incorporated into the distillate, consists of a mixture of vanillin with xylene musk.
- the agent also includes distillation residues of oxo alcohols and / or an ester, an alcohol, a ketone, an aldehyde having from 10 to 20 carbon atoms or a mixture of such compounds.
- US Patent 3,151,956 recommends incorporating diesel fuels an odor mask comprising benzyl salicylate, preferably in combination with oxo-synthesis derivatives and / or vanillin, synthetic musks (based on ter-butyl-nitro-benzenes), diethyl phthalate, the ionone, eugenol.
- application WO 01/74141 recommends, in order to reduce the unpleasant odor of these products, to employ a thiazole of formula R- (S) n -TZ- (S) n -R, TZ representing a thiazole ring, in combination with an odor mask consisting of conventional odor compounds including aromatic esters.
- thiazoles can not be used in fuels, on the one hand because they have different odors from those of lubricants, and on the other hand because of the fact that these compounds provide significant quantities of fuels. nitrogen and sulfur, which goes against the current environmental constraints that require on the contrary to reduce the nitrogen and sulfur content of fuels.
- compositions described in the prior art have an effectiveness limited.
- hydrocarbon fuels and fuels very specific olfactory profiles, which may vary according to the types of cuts used (light or heavy) and according to the origin of these cuts. It proves thus particularly difficult to develop an additive or a composition resorption additives that significantly improve the odor of hydrocarbon cuts usually constituting fuels, whatever their nature and origin.
