Khim., Yerevan, USSR). Arm. Khim. 88954-07-8 and 10035-10-6 which are cas registry numbers of chemicals are mentioned. Zh., 36(7), 456-62 (Russian) 1983. CODEN: AYKZAN. ISSN: 0515-9628. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Reaction of Bu3P with PhCYCH at 120° gave I whose reaction with HBr, MeBr, CH2:CHCH2Br, MeCH:CHCH2Br and AcCl was studied. In all cases, 2 products were formed which correspond to 2 betaine structure with the Ph group in the a- or b-positions. .

Numerical simulation of unsteady laminar flame propagation via the method of lines: further mathematical refinements and results obtained on halogen inhibition

Numerical simulation of unsteady laminar flame propagation via the method of lines: further mathematical refinements and results obtained on halogen inhibition. Galant, S. (Div. Energ., Soc. Bertin Cie., Plaisir 78370, Fr.). Combust. Sci. Technol., 34(1-6), 111-48 (English) 1983. CODEN: CBSTB9.Several reagents with their cas registry numbers 10035-10-6 and 7647-01-0 are used here. ISSN: 0010-2202. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) A specific version of a std. numerical scheme, viz. the method of lines is used to solve unsteady laminar flame propagation equations. A summary of novel results is given which includes accuracy properties of 5-point noncentral spatial discretization schemes, when coupled with explicit time integration schemes as in the present numerical method. The usefulness of the numerical scheme is illustrated on the basis of extensive computations dealing with H2-O2-N2 laminar premixed flames inhibited by halogen-contg. species, e.g. HBr and HCl. Results cover steady-state flame structures, unsteady HBr extinction numerical expts., and sensitivity anal. of the obtained results to input transport data. Kinetic and transport data must be input in a coherent manner to insure adequate comparison with exptl. results. A discussion of a min. kinetic rate set to adequately model halogen inhibition is presented. .
