Abstract: The present invention is a method of making 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-dione (where R is H or a hydrocarbyl group) comprising the step of contacting 1,4,5,8-tetrachloroanthraquinone with a mixture of R-anilines comprising at least two different R groups, under conditions to produce 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-dione. The present disclosure also provides a reaction mixture of 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-dione characterized by having the R groups on at least 75% of the 1,4,5,8-tetrakis(R-amino)anthracene-9,10-dione molecules in the mixture be comprised of 2 or more different R groups. The present disclosure also provides a method of improving the solubility of 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-dione in aromatic hydrocarbons distilled from crude oil, comprising selecting a mixture of 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-diones which are characterized by having at least 75% of the 1,4,5,8-tetrakis(R-phenylamino)anthracene-9,10-dione molecules in the mixture comprise two or more different R groups. The compounds of the present invention exhibit a suitable UV visible absorbance profile making them suitable for use as a fuel marker.
