Ikeda, Takuo; Yamamoto, Masakazu; Nishimura, Shinji; Sugiyama, Hiroshi (Sumitomo Chemical Co., Ltd., Japan).In this experiment, several chemicals are used like 63555-38-4 Japan. JP 52008333 B4 8 Mar 1977 Showa, 5 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C09B062-70. APPLICATION: JP 69-61163 1 Aug 1969. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Reactive dyes I (R = SO3Na; R1 = H, OMe; R2 = SO2CH:CH2, SO2CH2CH2OSO3Na), greenish yellow on cotton, were prepd. For example, dehydrothio-p-toluidine-7,3'-disulfonic acid [5855-98-1] was diazotized, coupled with 3-(2-hydroxyethylsulfonyl)-4-methoxyacetoacetanilide [49743-58-0], and sulfated to give I (R = SO3Na, R1 = 4-MeO, R2 = 3-SO2CH2CH2OSO3Na) [35168-45-7] with higher color yield and lightfastness than conventional I (R = H, R1 = 2-MeO, R2 = 5-SO2CH2CH2OSO3Na). .
