Abstract:
The invention relates to the use of selected dibenzanthrone or isodibenzanthrone derivatives as marking substances for liquids, especially for mineral oils. The invention also relates to fuel and lubricant additive concentrates, in addition to mineral oils containing at least one such dibenzanthrone or isodibenzanthrone derivative.
Abstract:
The invention relates to a method for the marking of hydrocarbons, by addition of at least one first marking agent( subsequently referred to as first marking agent), characterised in that, in addition, at least one further second marking agent is added to the hydrocarbon, which, under conditions for removal of the first marking agent, is not completely removable from the hydrocarbon. The invention further relates to hydrocarbons which are to be marked by said method, solutions for marking hydrocarbons, containing at least one first marking agent and at least one second marking agent as defined by the method according to the invention and optionally containing further additives.
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.
Abstract:
The present invention relates to a method of marking liquids using at least two markers, wherein said markers absorb in the 600-1200 nm region of the spectrum and reemit fluorescent light and the absorption range of at least one marker overlaps with the absorption range of at least one other marker. The present invention further relates to a method for detecting markers in liquids marked by the method of the invention, which comprises using light sources which emit radiation in the absorption ranges of said markers and detecting the fluorescent light reemitted by said markers, at least one of said light sources emitting radiation in the overlapping absorption range of at least one marker with that of at least one other marker and the number of light sources being less than or equal to the number of markers. The present invention further relates to liquids marked by the method of the invention.
