APPLICATION: JP 82-41264 15 Mar 1982. DOCUMENT TYPE: Patent CA Section: 72 (Electrochemistry) A button-type air battery is described, which consists of the following: (1) a cathode catalyst contg. active C, MnO2 having 31 crystal (phases), and a conductor; (2) a Zn anode; and (3) an alk. electrolyte. Thus, the battery having an initial open-circuit voltage 1.35-1.38 V and a cathode catalyst contg. Mn2O3 and g, a, b and/or d MnO2 had an open-circuit potential of 1.32-1. 1317-34-6 and 7440-66-6 are just another two chemicals used in this study.34 V after storing at 60° for 20 days while keeping the air hole closed. .

Catalytic properties of defective brannerite-type vanadates. III. Oxidation of o-xylene on manganese vanadium molybdenum oxide (Mn1-xfxV2-2xMo2xO6). Ziolkowski, Jacek; Gasior, Marian (Inst. Catal. Surf. Chem., Pol. Acad. Sci., Krakow 30-239, Pol.). J. Catal., 84(1), 74-84 (English) 1983. CODEN: JCTLA5. ISSN: 0021-9517. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) Section cross-reference(s): 25 A model of sites active in oxidn. reactions is proposed. This model, designated BSMAS, is based on crystallochem. considerations and the assumption that the individual catalytic activity of a given surface O atom is proportional to its reciprocal bond-strength sum. The studies are extended to the oxidn. of o-xylene. The conversion and yield of phthalic anhydride, tolualdehyde, phthalide, maleic anhydride, CO, and CO2 were detd. as a function of temp., contact time, catalyst compn., and type of preferentially exposed crystallog. plane ((201) or (202)). The reaction scheme is composed of stage total combustion and of a 1-site rake-reaction along which C8 products are formed. The scheme is common for both planes and it does not alter with catalyst compn., but, as is shown by results from changes in conversion, yields, and selectivities to different products, the rate const.In this experiment, several chemicals are used like 1313-27-5 and 1317-34-6 of the elementary steps does depend on the plane exposed and the compn. of the solid. Discussion in terms of the BSMAS model makes it possible to indicate the structure of active sites on which the above mentioned reactions may take place and explain the plane effect and dependence of the reaction pattern on catalyst compn. .
