    Abstract: Hidrocarburos que contienen como sustancia marcadora uno ovarios benzaldehídos de la fórmula Ien la queel anillo A puede estar benzoanelado, R1 , R2 y R3 significan, cada uno independientemente del otro hidrógeno, hidroxi, C1 -C15 -alquilo, C1 -C15 -alcoxi, ciano, nitro o un radial de la fórmula NR4 R5 o COOR6 ,donde R4 significa hidrógeno o C1 -C15 -alquilo, que puede estar interrumpido por 1 hasta 4 átomos de oxígeno en función de éter y que eventualmente está sustituido por fenilo, R5 significa C1 -C15 -alquilo, que puede estar interrumpido por 1 hasta 4 átomos de oxígeno en función de éter y que eventualmente está sustituido por fenilo, o un radical de la fórmula L-NX1 X2 , donde L significa C2 -C8 -alquileno y X1 y X2 significan, cada uno independientemente del otro, C1 -C6 -alquilo o representan junto con el átomo de nitrógeno que los une un radical heterocíclico saturado con 5 ó 6 miembros, que puede contener aún un átomo de oxígeno en el anillo, y R6 significa hidrógeno, C1 -C15 -alquilo, que puede estar interrumpido por 1 hasta 4 átomos de oxígeno en función de éter, o significa un radical de la fórmula L-NX1 y X2 tienen cada vez el significado arriba indicado.como sustancias marcadoras para hidrocarburos.

    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.
