Abstract
Abstract 4,4'-Diaminostilbene-2,2'-disulphonic acid was condensed with two moles of cyanuric chloride to give 4,4'-[(4,6-dichloro-s-triazin-2-yl)amino] stilhene-2, 2'-disulphonic acid, which was then condensed with two moles of morpholine to afford 4,4'-bisf(4-morpholino-6-chloro-s-triazin-2-yl)aminoj stilbene-2, 2'-disulphonic acid. This compound was then further condensed with two moles of an arylurea and arylthiourea to give 4,4'-bis[(4-morpholino-6-arylureido-s-triazin-2-yl)amino] stilbene-2,2'-disulphonic acid and 4,4'-bis [(4-morpholino-6-asylthiouscido-s-triazin-2-yl)amino] stilbene-2,2'-disulphonic acids respectively. These compounds were applied as fluorescent brightening agents on cotton and nylon fibres and gave excellent results.
