Brit. 3445-11-2 is the cas registry number of certain chemical which is used as reagents here. GB 1478697 6 Jul 1977, 5 pp. (English). (United Kingdom). CODEN: BRXXAA. CLASS: IC: C09B001-00. APPLICATION: GB 74-44396 14 Oct 1974. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Four pyrrolidonyloxyanthraquinone dyes and their hydrolysis products were manufd. which dyed arom. polyester fibers brilliant red to blue shades. Thus, treatment of N-(b-hydroxyethyl)pyrrolidone [3445-11-2] with 1-amino-2-bromo-4-(p-toluenesulfonamido)anthraquinone [26868-32-6] gave anthraquinone dye I (R = p-toluenesulfonyl) [65161-34-4] which was hydrolyzed in aq. H2SO4 giving anthraquinone dye I (R = H) [65161-38-8] which dyed arom. polyester material bluish-red shades. ..
