    • A method for marking a liquid petroleum hydrocarbon. The method comprises adding to the liquid petroleum hydrocarbon at least one substituted anthraquinone dye having formula (I) wherein R1 and R2 independently are hydrogen, hydroxy, OR11, amino or NR11R12; R3 and R5 independently are alkyl, aryl, aralkyl, heteroalkyl or heterocyclic; R4 and R6 independently are hydrogen or alkyl; R7, R8, R9 and R10 independently are cyano, nitro or hydrogen, provided that at least two of R7, R8, R9 and R10 are cyano or nitro; R11 is alkyl, aryl, aralkyl, heteroalkyl, heterocyclic or alkanoyl; R12 is hydrogen or alkyl; and wherein the substituted anthraquinone dye(s) has an absorption maximum in the range from 690 nm to 1000 nm.
    • 一种液体石油烃的标记方法。 该方法包括向液体石油烃中加入至少一种具有式(I)的取代的蒽醌染料,其中R 1和R 2独立地是氢,羟基, 11,氨基或NR 11 R 12; R 3和R 5独立地是烷基,芳基,芳烷基,杂烷基或杂环; R 4和R 6独立地是氢或烷基; R 7,R 8,R 9和R 10独立地是氰基,硝基或氢,条件是在 R 7,R 9,R 9和R 10中的至少两个是氰基或硝基; R 11是烷基,芳基,芳烷基,杂烷基,杂环或烷酰基; R 12是氢或烷基; 并且其中取代的蒽醌染料的吸收最大值在690nm至1000nm的范围内。
