    • Preparation of perylene-3,4-dicarbimides by reaction of a perylene-3,4,9,10-tetracarboxylic acid or of the corresponding anhydrides with a primary amine by performing the reaction in the presence of a tertiary nitrogen base as solvent and of a transition metal or transition metal salt as catalyst, and purification of perylene-3,4-dicarbimides obtained by reaction of a perylene-3,4,9,10-tetracarboxylic acid or of the corresponding anhydrides with a primary amine by heating the crude products initially in N-methylpyrrolidone and then treating the resulting N-methylpyrrolidone adducts in the presence of an organic diluent with a base, and if desired subjecting the subsequently isolated products to an additional treatment with an aqueous acid, and also novel perylene-3,4-dicarbimides and their use as fluorescent dyes, pigments or pigment additive precursors.

    • A method for the qualitative or quantitative determination of the deleterious agent in a substantially non-aqueous medium, such as an oil. The method involves using a non-azo 1,8-naphthalimide dye for the detection or quantitation of the total hydrogen ion activity in a substantially non-aqueous medium. The method includes the steps of: Mixing the dye with the substantially non-aqueous medium, which may or may not contain any hydrogen ion, to form a mixture; irradiating the mixture with a fluorescent light sufficient to cause the mixture to emit a detectable fluorescent emission spectrum; detecting the fluorescent emission spectrum of the mixture; and comparing the detected fluorescent emission spectrum with standard fluorescent emission spectra generated by reacting the dye with different known hydrogen ion activities, wherein differences between the fluorescent emission spectra compared are dependent upon the presence or levels of the hydrogen ion activity present in the mixture.
    • 用于在基本上非水介质如油中定性或定量测定有害剂的方法。 该方法包括使用非偶氮1,8-萘二甲酰亚胺染料来检测或定量在基本上非水介质中的总氢离子活度。 该方法包括以下步骤:将染料与基本上非水介质混合,其可以含有或不含有任何氢离子以形成混合物; 用足以使混合物发射可检测的荧光发射光谱的荧光照射混合物; 检测混合物的荧光发射光谱; 并且将检测到的荧光发射光谱与通过使染料与不同的已知氢离子活性反应产生的标准荧光发射光谱进行比较,其中所比较的荧光发射光谱之间的差异取决于混合物中存在的氢离子活性的存在或水平。
