Aqueous (3-chloro-2-hydroxypropyl)trimethylammonium chloride solutions. (Yokkaichi Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58174349 A2 13 Oct 1983 Showa, 3 pp. 106-89-8 and 593-81-7 are also occured in this study. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C091-26; C07C089-02. APPLICATION: JP 82-57286 8 Apr 1982. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Aq. solns. of Me3N.HCl (I) [593-81-7] are mixed continuously with epichlorohydrin (II) [106-89-8] at molar ratio 1 and temp. <70° to prep. aq. (3-chloro-2-hydroxypropyl)trimethylammonium chloride (III) [3327-22-8] solns. Thus, mixing of 0.98 kg/min 60% aq. I and 0.57 kg/min II at 30° with retention time 60 min gave a crude soln. contg. III 72.5, impurities 2.2, and water 25.3%, compared with 63.8, 10.9, and 25.3%, resp., for a crude soln. prepd. by adding 23.2 kg II to 40.0 kg 60% aq. I at 30° during 5 h. .

Dyeing polyester-cellulose fiber blends. Dvorsky, Drahomir; Cerovsky, Karel (Czech. ). Czech. CS 205608 B 1 Sep 1983,4 pp. (Czech). 100-97-0 and 88381-05-9 are cas registry numbers. These chemicals are also mentioned in this article. (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: D06P005-22. APPLICATION: CS 78-8095 7 Dec 1978. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Polyester-cellulose fiber blends are dyed levelly by disperse and anionic dyes in the presence of R3NCH2CH(OH)CH2Cl+ Cl- [I, R = C1-4 (hydroxy)alkyl] antimigration agent and 0.1-6% hexamethylenetetramine (II) [100-97-0] (based on cellulose fibers), dried at 90-120°, and fixed at 180-220° for 10-180 s. Thus, a polyester-cotton fabric was dyed in a bath contg. C.I. Disperse Blue-40 10, C.I. Direct Blue-106 5, I (R = Me) [3327-22-8] 20, II 20, urea 50, and Na alginate 5 g/L, dried at 90°, and fixed with hot air at 210° for 60 s to give a level blue dyeing. .
