- Builders for cleaning compositions
- Builders for cleaning compositions. Ebara, Toshiro (Koei Chemical Co., Ltd., Japan). Japan. Kokai JP 52140507 24 Nov 1977 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C11D003-20. APPLICATION: JP 76-58321 19 May 1976. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Sodium formate (I) [141-53-7] was used as a builder for cleaning compns. contg. Na oleate (II) [143-19-1], Na laurylbenzenesulfonate [25155-30-0], or poly(oxyethylene) oleyl ether [9004-98-2]. Thus, a cleaning compn. comprised 0.2 g II and 0.6 g I.
- Removing hydrogen sulfide from gas streams
- Removing hydrogen sulfide from gas streams. (Rhone-Poulenc S. A., Fr.). Japan. Kokai JP 52018466 12 Feb 1977 Showa, 14 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D053-34. APPLICATION: JP 75-90309 25 Jul 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 48, 59 A gas stream is contacted with (1) an aq. soln. (which has pH 3-11 and can maintain metals in a sol. form in the soln.) contg. water-sol. polyvalent metal chelates including chelate-forming amino acids, i.e., R3-nN[(CH2)mCO2H]n (R = CH2CH2OH, CH2CH(OH)CH3, or C1-4 alkyl; m = 2-3; n = 1-3) or R12NZNR12 [R1 = CH2CH2CO2H, (CH2)3CO2H, CH2CH2OH, CH2CH(OH)CH3, or CH2CH2NR12; Z = ethylene, propylene, trimethylene, 1,2-cyclohexylene, or o-phenylene], and with (2) alkali metal, alk. earth metal, NH4, or amine salts of acids having pKa values 1.2-6 at 25°. The aq. polyvalent metal chelate soln. is contacted with a gas contg. mol. O, and the chelate is then regenerated. S and/or dialkyl disulfide are removed from the aq. metal chelate soln. H2S and/or alkyl mercaptans are converted to elemental S and/or dialkyl disulfides, resp. The amts. of H2S and/or alkyl mercaptan in the gas are reduced. Thus, by using HEDTA-Fe chelate at pH 9.3-7.1 and adding Na formate [141-53-7], air contg. 13,000 ppm H2S was completely desulfurized. The process is also applicable to the purifn. of fuel gases and petroleum refinery gases.
