Abstract: The present invention relates to a method for determining the identity or non-identity of at least one chemical compound V' homogeneous y distributed in a medium, by a) exposing the medium containing at least one homogeneously distributed chemical compound V' to analysis radiation with a variable wavelength lambda, and b) determining the spectral measurement function I'(lambda) with the aid of the absorbed, reflected, emitted and/or scattered radiation, wherein a correlation function K(deltalambda,c',c) is determined according to Equation I K ⁡ ( delta ⁢ ⁢ lambda , c ' , c ) = 1 / N . ∫ - ∞ + ∞ ⁢ I ' ⁡ ( lambda , c ' ) . I ⁡ ( lambda + delta ⁢ ⁢ lambda , c ) ⁢ ⁢ ⅆ lambda ( I ) in which K(deltalambda,c',c) denotes the correlation depending on the relative shift deltalambda of the functions I'(lambda,c') and I(lambda,c) and the concentrations c' and c of the at least one chemical compound V' and V, c' denotes the concentration of the at least one chemical compound V' homogeneously distributed in the medium, with a known or suspected identity, c denotes the concentration of the at least one chemical compound V homogeneously distributed in the medium, with a known identity, I'(lambda,c') denotes the measurement function of the at least one homogeneously distributed chemical compound V' in a medium containing the concentration c', I(lambda,c) denotes the comparison function of the at least one homogeneously distributed chemical compound V in a medium containing the concentration c, and N denotes a normalization factor and identity or non-identity between the compounds V and V' is determined with the aid of the correlation function K(deltalambda,c',c).

Abstract: Phthalocyanines of the formulawhereMe is twice hydrogen, twice lithium, magnesium, zinc, copper, nickel, VO, TiO, AlCl, AlOH, AlOCOCH3, AlOCOCF3, SiCl2 or Si(OH)2,at least four of the radicals R1 to R16 are each independently of the others a five- or six-membered saturated nitrogen-containing heterocyclic radical which is bonded to the phthalocyanine structure via a ring nitrogen atom and which can additionally contain further hetero atoms, andany remaining radicals R1 to R16 are each hydrogen, halogen, hydroxysulfonyl or C1-C4-dialkylsulfamoyl,subject to the proviso that tetrakispiperidinylphthalocyanine shall be excluded,and heterocyclyl-substituted phthalocyanines are useful for marking liquids, in particular mineral oils.
