Abstract: Use of compounds from the class of the phthalocyanines, naphthalocyanines, nickel dithiolene complexes, aminium compounds of aromatic amines, methine dyes or azulenesquaric acid dyes which have their absorption maximum in the range from 600 to 1,200 nm and/or a fluorescence maximum in the range from 620 to 1,200 nm, as markers for liquids, a process for detecting markers in liquids, and a detector suitable for this purpose.

Abstract: Described is a method for marking liquids with at least two marker substances. The marker substances are absorbent in the spectral range of 600 to 1200 nm and emit fluorescence radiation as a result. The absorption range of at least one marker substance overlaps the absorption range of at least one other marker substance. Also described is a method for detecting marker substances in liquids which have been marked by the above method. This method is characterised in that the sources of radiation used emit radiation in the absorption ranges of the marker substances, so that the fluorescence radiation emitted by the marker substances can then be detected. At least one of the radiation sources emits radiation in the absorption range in which at least one marker substance overlaps with at least one other marker substance, and the number of sources of radiation used is smaller than, or the same as, the number of marker substances. Also described are liquids which have been marked by the above method.

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.
