Transformer oil mixtures

Transformer oil mixtures. (Westinghouse Electric Corp., USA). Jpn. Kokai Tokkyo Koho JP 59138005 A2 8 Aug 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01B003-24; C09K015-08. APPLICATION: JP 84-3719 13 Jan 1984. PRIORITY: US 83-457791 13 Jan 1983. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 76 The synergistic increase in the dielec. power factor of transformer oil mixts. of mineral oil and C2Cl4 [127-18-4] upon aging was suppressed by addn. of 20-500 ppm tautomeric phenols and 10-100 ppm antioxidants. Thus, after aging 7 days at 125°, the dielec. power factor of a mixt. contg. 25 wt.% mineral oil, 75 wt.% C2Cl4, 50 ppm 80 wt.% N-methylpyrrole [96-54-8], and 200 ppm p-tert-amylphenol [80-46-6] was reduced from 4.8 to 0.3% by addn. of hydroquinone [123-31-9] (0.5 wt.% to the total mixt.).

Chemical disinfectant and sterilant composition comprising acidic glutaraldehyde

Chemical disinfectant and sterilant composition comprising acidic glutaraldehyde. Martin, Howard (USA ). U.S. US 4469614 A 4 Sep 1984,4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A61L013-00; C11D003-48. NCL: 252106000. APPLICATION: US 83-468044 22 Feb 1983. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) A chem. disinfectant and sterilant, esp. for hard surfaces, comprises glutaraldehyde [111-30-8] in acidic form. The compns. also contain phenols, benzotriazole [95-14-7], sulfonates, and NaH2PO4. The pH of the compn. is 2.5-7.0. The compns. require no activation, have an indefinite shelf-life of ~1 yr, and leave no skin irritating deposit on instruments. A compn. contains glutaraldehyde (acidic) 15.46, o-phenylphenol [90-43-7] 1.98, p-tert-amylphenol [80-46-6] 0.07, benzotriazole 0.24, Na aryl alkyl sulfonate 0.24, citric acid [77-92-9] 0.24, NaH2PO4 8.07, and H2O 73.6 % by wt. This is used as a base stock soln. Benzotriazole and the sulfonate act as surfactants and corrosion inhibitors.
