1,3-Diarylpyrazoline fluorescent whitener: 1,3-Diarylpyrazoline fluorescent whitener. Noll, Bernd; Keil, Siegfried; Weinelt, Herbert; Chojnacki, Karlheinz; Raschke, Dieter (VEB Chemiekombinat Bitterfeld, Ger. Dem. Rep.). Ger. (East) DD 208465 A3 2 May 1984, 6 pp. (German). (German Democratic Republic). CODEN: GEXXA8. CLASS: IC: C07D231-06. APPLICATION: DD 82-242507 13 Aug 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Fluorescent whitener I [2744-49-2] is prepd. in high yield and purity (m. 224-226°) by mixing p-H2NSO2C6H4NHNH2 [4392-54-5] with ClCH2CH2COC6H4Cl-p [3946-29-0] in MeOH in the presence of NaHCO3 at 20-25°, stirring the mixt. at 20-25° for ~1 h, heating to 60-65°, and stirring at 60-65° for 2-5 h.

Roemhild, Hans Juergen; Hartmann, Horst; Noack, Horst (VEB Chemiekombinat Bitterfeld, Germany). Ger. (East) DD 287719 A5 7 Mar 1991, 4 pp. (German Democratic Republic).Chemicals with cas numbers 4392-54-5 and 137728-16-6 also play role. CODEN: GEXXA8. CLASS: ICM: C07D405-04. ICS: C09B057-02. APPLICATION: DD 89-332456 8 Sep 1989. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 27, 28 Coumarins I (R = H, Ph, p-tolyl, p-chlorophenyl, p-nitrophenyl, p-sulfamoylphenyl, 2,5-dichlorophenyl) are prepd. by cyclocondensation of RNHNH2 with 3-(acetoacetyl)-7-(diethylamino)coumarin (II) in a lower alc. contg. an acid. Quaternary salts are formed with MeX (X = MeSO4, halogen, 0.5 ZnCl4). For example, hydrazine was refluxed 1 h with II in a 2:1 mixt. of MeOH and 32% HCl to give 84% II (R = H). Quaternization was effected with Me2SO4, followed by addn. of ZnCl2 to give a dye which imparted brilliant greenish yellow shades to acrylic fibers. .
