Use of bis(stilbene) derivatives as fluorescent whiteners for organic textile materials. Weber, Kurt; Liechti, Peter; Meyer, Hans Rudolf; Siegrist, Adolf E. (Ciba-Geigy A.-G., Switz.Chemicals with cas numbers 33771-74-3 and 587-04-2 also play role.). Swiss CH 580702 15 Oct 1976, 12 pp. Division of Swiss 554,848, Addn. to Swiss 566,420. (Unavailable). (Switzerland). CODEN: SWXXAS. CLASS: IC: D06L003-12. APPLICATION: CH 69-4791 27 Mar 1969. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Fluorescent whiteners (I, R = Na, Na-K mixt.; R = Cl, SO2NMe2) were prepd. and used to whiten polyamide fibers and cotton finished with amino resins. Thus, a mixt. of 4,4'-bis[(diethoxyphosphinyl)methyl]biphenyl [17919-34-5], 2-ClC6H4CHO [89-98-5], and 2-NaO3SC6H4CHO [1008-72-6] was heated in the presence of KOH in DMF to give I(R = Na-K mixt., R1 = 2-Cl) [31207-32-6]. The other I were similarly prepd. .
