    • The present invention provides a compound having the formula:

      in which M is hydrogen, sodium, potassium, calcium, magnesium, ammonium, mono-, di-, tri- or tetra-C₁-C₄alkylammonium, mono-, di- or tri-C₁-C₄hydroxyalkylammonium or ammonium that is di- or tri-substituted by a mixture of C₁-C₄alkyl and C₁-C₄hydroxyalkyl groups; R₁ is a group having the formula:

      in which M has its previous significance and n is 1 or 2; and R₂ is O-C₁-C₁₂alkyl or N(R₃)(R₄) in which R₃ and R₄, independently, are hydrogen, C₁-C₁₂alkyl or C₁-C₄hydroxyalkyl, or R₃ and R₄, together with the nitrogen atom, are the atoms required to form a pyrrolidine, piperidine or morpholine group.
      The compounds of formula (1) are particularly useful as fluorescent whitening agents for cotton in discontinuous processes, in the course of which an acidic treatment, especially a finishing treatment using a polymer resin, occurs.
    • 本发明提供具有下式的化合物:其中M是氢,钠,钾,钙,镁,铵,一,二,三或四-C 1 -C 4烷基铵,其中M是氢,单 - ,二 - 或二 - 被C 1 -C 4烷基和C 1 -C 4羟烷基的混合物二或三取代的三-C 1 -C 4羟烷基铵或铵; R1是具有下式的基团:其中M具有其先前的含义并且n是1或2; 并且R 2为O-C 1 -C 12烷基或N(R 3)(R 4),其中R 3和R 4独立地为氢,C 1 -C 12烷基或C 1 -C 4羟烷基,或者R 3和R 4与氮原子一起为所需原子 以形成吡咯烷,哌啶或吗啉基团。 式(1)的化合物特别可用作不连续过程中用于棉花的荧光增白剂,其中发生酸处理,特别是使用聚合物树脂的整理处理。
