Smoke-suppressant additives for polyphosphazenes: Smoke-suppressant additives for polyphosphazenes. Dieck, Ronald L.; Quinn, Edwin J. (Armstrong Cork Co., USA). U.S. US 4026838 31 May 1977, 9 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08J009-10. NCL: 260002500FP. APPLICATION: US 76-712149 6 Aug 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Addn. of solid carboxylic acids suppresses smoke evolution from phosphazene polymer phenoxy derivs. Thus, p-sec-butylphenoxy p-methoxyphenoxy polyphosphazene contg. 1% trimesic acid (I) [554-95-0] had corrected max. sp. optical d. 80, and smoke value/g 16, compared with 152 and 32, resp., for polymer not contg.

Gas chromatographic-mass spectrometric identification of phenols and aromatic acids in river waters: Gas chromatographic-mass spectrometric identification of phenols and aromatic acids in river waters. Matsumoto, Genki; Ishiwatari, Ryoshi; Hanya, Takahisa (Fac. Sci., Tokyo Metrop. Univ., Tokyo, Japan). Water Res., 11(8), 693-8 (English) 1977. CODEN: WATRAG. DOCUMENT TYPE: Journal CA Section: 61 (Water) EtOAc exts. of water samples from 2 urban rivers in Tokyo were analyzed for phenols and arom. acids by a combined gas chromatograph-mass spectrometer after sepg. by solvent extn. and silica gel column chromatog. The following phenols and arom. acids were identified: pentachlorophenol [87-86-5], bisphenol A [80-05-7], phthalic acid [88-99-3], trimesic acid [554-95-0], p-hydroxybenzoic acid [99-96-7], vanillic acid [121-34-6], syringic acid [530-57-4], p-coumaric acid [7400-08-0], and ferulic acid [1135-24-6]. The presence of o- [69-72-7] and m-hydroxybenzoic acid [99-06-9] were suggested by mass fragmentog. The sources of these compds. are discussed.
