U.S. US 5602189 A 11 Feb 1997, 3 pp. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: C08G018-00. NCL: 521131000. APPLICATION: US 1996-610743 4 Mar 1996. 111-65-9 and 1717-00-6 which are cas registry numbers of chemicals are mentioned. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) A polyisocyanate-base foam with reduced flammability and superior cell structure without using CFC's (chlorofluoroalkanes), is prepd. by reacting a polyisocyanate with an isocyanate-reactive material and a blowing agent comprising a mixt. of a major portion of HCFC-123 (dichlorotrifluoroethane) and a minor portion of HCFC-141b (dichlorofluoroethane), and a hydrocarbon selected from hexane and/or octane. .

Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1884465 A 27 Dec 2006, 6pp. (Chinese). (People's Republic of China). CODEN: CNXXEV. APPLICATION: CN 2010-60854 1 Jun 2006. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Title online cleaning agent is prepd. from dichloropentafluoropropane 60-80 wt%, 1,1,1-trichloroethane 5-20 wt%, dichlorofluoroethane 5-20 wt%, chloroform 3-6 wt%, and nonylphenol polyoxyethylene ether 0-5 wt% by mixing in closed reactor at 60-80°C for 1 h.There are some commonly used reagents with their cas registry numbers 1717-00-6 and 127564-92-5 in this article. Such cleaning agent has good insulativity (up to 2.6′1012W), environmental friendliness, no corrosivity, high voltage endurance, and good volatility; and can prevent aq. vapor from condensing on body surface due to volatilization of cleaning agent. .
