    Abstract: The invention concerns a composition for use in particular as odorant of a gas fuel, more particularly of natural gas, comprising: 0.1 to 49.9 particles by weight of at least one alkyl sulphur (I) of formula: R1—S—R2, wherein R1 and R2, identical or different, represent: an alkyl radical comprising 1 to 4 carbon atom; or R1 and R2 together with the sulfur atom to which they are bound represent a saturated or unsaturated ring including 3 to 5 carbon atoms, optionally substituted by a C1-C4 alkyl or C1-C4 alkenyl; 50 to 99.8 parts by weight of at least two alkyl acrylates (II) the alkyl radicals of which comprise 1 to 12 carbon atoms, preferably 1 to 8: 0.001 parts by weight of at least compound (III) inhibiting polymerization of the alkyl acrylates (II).

    Abstract: Disclosed is a stabilized diesel fuel composition comprising a) a diesel fuel with a cetane number less than or equal to 50, b) an effective amount of at least one compound selected from the group consisting of the cetane improvers and c) i) an effective stabilizing amount of at least one compound selected from the group consisting of the stable nitroxide compounds or ii) an effective synergistic stabilizing amount of at least one compound selected from the group consisting of the stable nitroxide compounds and at least one antioxidant compound selected from the group consisting of the aromatic amine antioxidants and the hindered phenolic antioxidants. The cetane improvers are for example nitrate esters. The diesel fuel compositions exhibit improved filterability.
