    摘要: Novel crystalline needle forms of the fluorescent compounds disodium 4,4'-bis(4-anilino-6-morpholino-s-triazin-2-ylamino)-2,2'-stilbenedisulfonate and disodium 4,4'-bis(4,6-dianilino-s-triazin-2-ylamino)-2,2'-stilbenedisulfonate, useful as optical brightening agents, particularly when incorporated into detergent compositions. The novel crystalline forms are prepared by heating the compound in an aqueous alkaline medium containing excess amine reactant.
