Abstract

The invention relates to the use of benzaldehydes of the formula (I), in which ring A can be benzo-anellated and R1, R2 and R3 are hydrogen, hydroxy, C1-C15 alkyl, C1-C15 alkoxy, cyano, nitro or a radical of the formula NR4R5 or COOR6, in which R4 is hydrogen or possibly substituted C1-C15 alkyl, R5 is possibly substituted C1-C15 alkyl or a radical of the formula L-NX1X2, in which L is C2-C8 alkylene and X1 and X2 are mutually independently C1-C6 alkyl or, together with the nitrogen atom bonding them, a heterocyclic radical, and R6 is hydrogen, possibly substituted C1-C15 alkyl or a radical of the formula L-NX1X2, in which L, X1 and X2 have the above meanings, as marking agents for hydrocarbons, a process for detecting these benzaldehydes in hydrocarbons and hydrocarbons containing the above benzaldehydes.
