Removal of nitrogen compounds from nitrogen oxide-adsorbent liquids

Removal of nitrogen compounds from nitrogen oxide-adsorbent liquids. Oshima, Hiroshi; Saiki, Koji; Sawada, Hiromichi (Kanebo, Ltd., Japan). Japan. Kokai JP 51133182 18 Nov 1976 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D053-34. APPLICATION: JP 75-58362 15 May 1975. DOCUMENT TYPE: Patent CA Section: 59 (Air Pollution and Industrial Hygiene) Spent absorbent contg. N compds., from waste gas denitration, is concd. and heated at a temp. higher than room temp. to decomp. NO3- in the absorbent by reacting with amidosulfonic acid, imidodisulfonic acid, and/or their salt. Thus, a solid mixt. contg. NaNO3 1.53, NH2SO3Na [13845-18-6] 2.85, and Na2SO4 10.62 g was mixed with a soln. contg. 20.65 g conc. H2SO4 and 12 g water and heated at 100.degree.. The NO3- decompn. was 70, 72, 77, and 81% after 15, 30, 45, and 60 min, resp.

Dyeing or printing of fabrics containing cellulosic fibers

Dyeing or printing of fabrics containing cellulosic fibers. Sakurai, Tatsuo; Nomura, Toyofusa; Abe, Kazukuni (Asahi Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 52070187 10 Jun 1977 Showa, 6 pp. (Japanese). (Japan).There are some reagents like 959-52-4 is used in this study. CODEN: JKXXAF. CLASS: IC: D06P003-66. APPLICATION: JP 75-143929 5 Dec 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Colored fabrics, with improved dye absorption and crocking fastness, were prepd. by impregnating or printing fabrics with a compn. (pH .ltoreq. 7) contg. a reactive dye, a hexahydrotriazine compd. e.g., 1,3,5-triacryloylhexahydro-s-triazine (I) [959-52-4], .ltoreq. 1.0 mol of a sulfonic acid or salt contg. active H per mol triazine compd., and a halogenated acetic acid salt. Thus, a rayon taffeta was immersed in a mixt. (pH 5.0) contg. Levafix Blue P-3 GL 25, I 30, Na sulfamate [13845-18-6] 7.5, Na trichloroacetate [650-51-1] 20, urea 50, and Na alginate 4.5 g and H2O to make 1 L to 70% pickup, dried, and steamed 20 min at 105.degree. to give a colored fabric with good dye absorption and wet crocking fastness, whereas wet crocking fastness was poor for a fabric dyed with a similar compn. without I. .
