Liquid oxidative desizing agent and its use

Liquid oxidative desizing agent and its use. Adrian, Klaus; Roesch, Guenter (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3211677 A1 6 Oct 1983, 8 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D06L001-06. APPLICATION: DE 82-3211677 30 Mar 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Liq. oxidative desizing compns. comprise Na or NH4 persulfate 5-20, 31 surfactant chosen from C8-20-sec-alkanesulfonate, C4-12 alkylphenol ethoxylate contg. 6-12 ethylene oxide units, or C10-18 fatty alc. ethoxylate with 3-8 units of ethylene oxide 20-25, and H2O to 100%. Thus, a starch-sized cotton textile was impregnated with a soln. comprising 6% NaOH and 1.5% of a mixt. contg. nonylphenol ethoxylate [7775-27-1] (8 mol ethylene oxide) 5, sec-C11-17-alkanesulfonate 30, and Na persulfate 7%, and the remainder H2O. The textile was squeezed to a residual moisture content of 100%, steamed, and washed to give a textile with degree of desizing 8-9, whiteness degree 66.7%, and av. d.p. 2550.

Simultaneous removal of sulfur oxides and nitrogen oxides from waste gases

Simultaneous removal of sulfur oxides and nitrogen oxides from waste gases. Hino, Koichi (Sumitomo Electric Industries, Ltd., Japan). Japan. Kokai JP 51076163 1 Jul 1976 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D053-34. APPLICATION: JP 74-148942 27 Dec 1974. DOCUMENT TYPE: Patent CA Section: 59 (Air Pollution and Industrial Hygiene) A waste gas contg. SOx and NOx is contacted with an aq. Na2S2O8 soln. to oxidize the SOx and NOx, then treated with an alk. soln. Thus, a gas mixt. contg. NOx 108 and SOx 89 mL was passed through a soln. contg. Na2S2O8 [7775-27-1] 20, NaOH 20 g, and H2O 400 mL. The SOx and NOx removal were .apprx.99.9 and .apprx.98.9%, resp.
