    Abstract: The invention relates to the use of benzaldehydes of the formula (I), in which ring A can be benzo-anellated and R , R and R are hydrogen, hydroxy, C1-C15 alkyl, C1-C15 alkoxy, cyano, nitro or a radical of the formula NR R or COOR , in which R is hydrogen or possibly substituted C1-C15 alkyl, R is possibly substituted C1-C15 alkyl or a radical of the formula L-NX X , in which L is C2-C8 alkylene and X and X are mutually independently C1-C6 alkyl or, together with the nitrogen atom bonding them, a heterocyclic radical, and R is hydrogen, possibly substituted C1-C15 alkyl or a radical of the formula L-NX X , in which L, X and X have the above meanings, as marking agents for hydrocarbons, a process for detecting these benzaldehydes in hydrocarbons and hydrocarbons containing the above benzaldehydes.

    Abstract: In a method of marking hydrocarbons by addition of at least one first marker, at least one second marker which cannot be removed completely from the hydrocarbons under the conditions of the removal of the first marker or markers is additionally added to the hydrocarbons. Hydrocarbons which have been marked by such a method and solutions comprising at least one first marker and at least one second marker as defined in the method of the present invention and also, if desired, further additives for marking hydrocarbons are also provided by the invention.
