Shock tube and modeling study of acetylene oxidation
Shock tube and modeling study of acetylene oxidation. Hidaka, Yoshiaki; Eubank, C. S.; Gardiner, W. C., Jr.; Hwang, S. M. (Fac. Sci., Ehime Univ., Matsuyama 790, Japan).Several reagents such as 74-86-2 is used here. J. Phys. Chem., 88(5), 1006-12 (English) 1984. CODEN: JPCHAX. ISSN: 0022-3654. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) C2H2 oxidn. was studied behind incident shock waves at 1300-2200 K with llaser-schlieren techniques. A computer-simulation study was performed to det. the important elementary reactions. Data anal. using a 23-reaction mechanism showed that relatively few steps play significant roles in detg. ignition behavior. The mechanism was tested against a variety of exptl. data in the literature. .
Infrared multiple-photon decomposition of trans-CHD=CDH
Infrared multiple-photon decomposition of trans-CHD=CDH. Majima, Tetsuro; Ishikawa, Yoichi; Arai, Shigeyoshi; Hirokami, Shunichi (Inst. Phys. Chem.Chemicals with cas numbers 74-86-2 and 1333-74-0 also play role. Res., Wako, Japan). Reza Kagaku Kenkyu, 5, 125-33 (Japanese) 1983. CODEN: RKAKDK. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The CO2 laser-induced IR multiphoton decompn. of trans-CHD:CHD (I) was studied as a function of pulse no., I pressure, laser fluence, and Ar pressure. The ratio of H2 to C2H2 was ~1, and H2:HD:D2 xC2D2:C2HD:C2H2 = 1:2:1. This result was explained by 4 unimol. processes of highly vibrationally excited I: mol. elimination of H, isomerization into cis-CHD:CHD, splitting of C-H bond, and fragmentation into C2 and H. .
