    • The present invention provides a compound having the formula: ##STR1## in which M is hydrogen, sodium, potassium, calcium, magnesium, ammonium, mono-, di-, tri- or tetra-C.sub.1 -C.sub.4 alkylammonium, mono-, di- or tri-C.sub.1 -C.sub.4 hydroxyalkylammonium or ammonium that is di- or tri-substituted by a mixture of C.sub.1 -C.sub.4 alkyl and C.sub.1 -C.sub.4 hydroxyalkyl groups; R.sub.1 is a group having the formula: ##STR2## in which M has its previous significance and n is 1 or 2; and R.sub.2 is O--C.sub.1 -C.sub.12 alkyl or N(R.sub.3)(R.sub.4) in which R.sub.3 and R.sub.4, independently, are hydrogen, C.sub.1 -C.sub.2 alkyl or C.sub.1 -C.sub.4 hydroxyalkyl, or R.sub.3 and R.sub.4, 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-C1 C4烷基铵,由C1-C4烷基和C1-C4羟烷基的混合物二或三取代的单,二或三-C 1 -C 4羟烷基铵或铵; R1是具有下式的组:其中M具有其先前的含义,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独立地是氢,C 1 -C 2烷基或C 1 -C 4羟烷基,或者R 3和R 4与氮原子一起是所需的原子 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工艺中用于棉花的荧光增白剂,其中酸性处理,特别是使用聚合物树脂的整理处理发生。
