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 becomprised 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.
本发明是一种制备1,4,5,8-四(取代苯基氨基)蒽醌-9,10-二酮(其中R为H或烃基)的方法,包括将1,4,5,8-四氯蒽醌与至少含有两种不同R基团的R-苯胺混合物接触,以产生1,4,5,8-四(取代苯基氨基)蒽醌-9,10-二酮。本公开还提供了一种1,4,5,8-四(取代苯基氨基)蒽醌-9,10-二酮的反应混合物,其特征在于至少75%的1,4,5,8-四(取代氨基)蒽醌-9,10-二酮分子中的R基团由两种或更多不同的R基团组成。本公开还提供了一种提高1,4,5,8-四(取代苯基氨基)蒽醌-9,10-二酮在从原油蒸馏出的芳香烃中的溶解度的方法,包括选择至少75%的1,4,5,8-四(取代苯基氨基)蒽醌-9,10-二酮分子中含有两种或更多不同R基团的混合物。本发明化合物具有适当的UV可见吸收特性,适用于用作燃料标记剂。
