    • Fluorescent compounds of the formula: wherein R1 and R2 are either both SO3M, or one of R1 and R2 is SO3M and the other is COOM, where M is selected from the group consisting of H, Na, K, Rb, Cs, Li or ammonium, are described and claimed. These inert flurorescent compounds have been found to be resistant to oxidizing biocides. One process for making these compounds is described and claimed as the condensation between a 1,8-naphthalic anhydride possessing the desired functionalities and the appropriately substituted o-phenylene diamine. Alternatively, o-amino-nitro-aromatics may be condensed with the various 1,8-naphthalic anhydrides when the in situ reduction of the nitro group is accomplished with a suitable reducing agent such as iron powder. The resulting fluorescent compounds can be used as inert fluorescent tracers in industrial water systems.
    • 下式的荧光化合物:其中R 1和R 2都是SO 3 M,或者R 1和R 2中的一个是SO 3 M,另一个是COOM,其中M选自H,Na,K,Rb,Cs,Li或 铵,被描述和要求保护。 已发现这些惰性荧光化合物对氧化杀生物剂具有抗性。 一种制备这些化合物的方法被描述和要求保护为具有所需官能度的1,8-萘二甲酸酐与适当取代的邻苯二胺之间的缩合。 或者,当硝基的原位还原用合适的还原剂如铁粉末完成时,邻氨基 - 硝基 - 芳族化合物可与各种1,8-萘二酸酐缩合。 所得荧光化合物可用作工业水系统中的惰性荧光示踪剂。
