Determination of amines in the atmosphere by FTD gas chromatography

Determination of amines in the atmosphere by FTD gas chromatography. Fukunaga, Kenichi; Kichiji, Kiyoshi; Furutani, Chozo; Hayada, Toshifumi (Yamaguchi Prefect. Environ. Pollut. Res. 75-50-3 and 124-40-3 are cas registry numbers. These chemicals are also mentioned in this article. Cent., Yamaguchi, Japan). Yamaguchi-ken Kogai Senta Nenpo, 8, 15-19 (Japanese) 1982. CODEN: YKSNDQ. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 80 MeNH2 (MMA) [74-89-5], Me2NH (DMA) [124-40-3], and Me3N .(TMA) [75-50-3] in air were detd. by gas chromatog. using 4 different columns; ASC-L for column I, Amipack 124 for column II, 5% Squalane [111-01-3] + 2% KOH on Chromosorb 104 [39429-20-4] for column III, and 15% diglycerol [59113-36-9] + 5% tetraethylenepentamine [112-57-2] on Chromosorb W + DMCS for column IV. Column I was suitable for sepn. of the 3, II for MMA, III for DMA, and IV for TMA. The method enables detn. of TMA from an 1-L air sample from a fish waste processing plant environment, and the TMA level was 6.9, 26, and 89 ppb for 3 sep. samples. .

Decomposition of methylamine over ruthenium black

Decomposition of methylamine over ruthenium black. Orita, Hideo; Naito, Shuichi; Onishi, Takaharu; Tamaru, Kenzi (Fac. Sci., Univ. Tokyo, Tokyo 113, Japan). Bull. 7440-18-8 and 74-89-5 are cas registry numbers. These chemicals are also mentioned in this article. Chem. Soc. Jpn., 56(11), 3390-2 (English) 1983. CODEN: BCSJA8. ISSN: 0009-2673. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The decompn. of MeNH2 over Ru black was investigated in the presence and absence of H. The dependence of reaction rate on the pressures of reactants was also examd. MeNH2 decompd. rapidly to NH3 and deposited carbon species (CHx(a)) over clean Ru black in the absence of H. The hydrogenation of CHx(a) after the decompn. of amines produced hydrocarbons in the range C1-C4 whose distribution was dependent on the way CHx(a) was accumulated. .
